12 Volt DC Electric Connector – SAE 2 Pin

by on Jul.03, 2017, under Configurations

Used to be that where one might 1st encompass an SAE 2 Pin connector would be in a 12 volt DC automotive circuit.

Clearly, the “SAE” (Society of Automotive Engineers) component of the designation is indicative of this initial application.

Widely available is the Hopkins 47965 product available in the trailer wiring department of discount automotive stores.

Later on down the road, it would probably be seeing it on battery charge maintenance equipment like a Deltran Battery Tender.

These days, one’s first exposure could very well be on Portable Solar Power equipment being used to charge hand held electronics.

Current fears regarding terrorism and political unrest has prompted a huge marketplace for the emergency preparedness industry.

The SAE 2 Pin connector configuration used in automotive applications filled the bill at the time, but today’s applications have driven further development.

More frequent coupling and uncoupling in current applications precipitated the the need for greater strain relief, and grip.

Current applications have also led to surface mount configurations, as well as shrouded configurations to minimize exposure to environmental elements.

SAE 2 Pin use by portable solar manufacturers in the development of products serving the US Military, as well as the Civilian marketplace, has prompted additional applications and significant DIY (do-it-yourself) use.

We have been serving this market with SAE 2 Pin assemblies employing enhanced configurations, as well as a wider range of AWG options.

Latest List of Applications for SAE 2 Pin Connector Assemblies

by on Jun.28, 2017, under Application

Thought after close to 10 years of developing a product line of SAE 2 Pin Connector Assemblies, I’d take an opportunity to share the growing list of applications we’ve discovered through contact with both DIY and commercial customers.

No doubt the largest number of inquiries and sales are related to portable solar power applications.  This makes sense, as many pieces of portable solar equipment come equipped with SAE 2 Pin Connections.

Government / Military applications have driven significant government contractor inquiries and sales.  Specifically, electronic target system target moving apparatus for tactical training has been an application we’ve encountered.  Meeting greater specification and documentation requirements has been key to this business.

The SHTF / Prepper emergency preparedness industry has certainly prompted many to consider portable backup power equipment, and SAE 2 Pin Connectors lend themselves to ready coupling with loads, often a 12 volt charger.

Battery Charge Maintenance continues to be a major source of inquiries and sales, as well.  These applications can range from motorcycle, ATV / 4-wheeler, snowmobile, street rod, and boat, to camper, travel trailer, and RV.

Be it, hiking, hunting, fishing, camping, backpacking, or cross-country travel – there’s a sun in the sky, and batteries to be charged.  Hand held electronics – cameras, radios, GPS, iPods, iPhones, and iPads, they all need charging via a charger.

Speaking of radios – Ham Radio enthusiasts have even driven development of an alternate assembly with a lighter gauge switch leg.  I was advised that certain models of Motorola Radio, specifically utilize this particular arrangement.

The Surveying industry has even brought inquiries and sales opportunities, as well.  Clearly, use of their electronics in the field drives a need to be able to charge on the go.

Garden, tree, and orchard spraying equipment connection has us corresponding with gardeners, farmers, and ranchers.

Portable food warming devices for use in door-to-door delivery, has emerged out of the international marketplace.

Computer simulation for scenario training is an industry we’ve served, as well.

Solar Capitalist DIY Solar Backup 12V Power Battery Bucket

by on Mar.07, 2017, under Application

Backup 12 Volt Power is a viable source to recharge handheld electronics, and even power communications equipment and low voltage backup lighting.

I am a cat lover (as well as a dog lover), and have 4 rescued cats. Seeing the value of the nifty buckets leftover from buying mass quantities of cat litter, I find all kinds of uses for them. That they are “stackable” makes them all the more attractive for storing all sorts of things, and economizing on space. Meanwhile, I dream up other uses, such as – I built my own portable electronic amplified coyote caller (see previous post).

A DIY (do-it-yourself) Solar Backup 12V Power Battery Bucket is another such use.

Certainly not that I invented the mental processes, but thoughts and the visualization that follows sometimes has me stumble upon realizing worthwhile combinations.

An example would be realizing that a hole drilled with a 7/8″ hole saw to facilitate installing one of our Panel / Bulkhead / Surface Mount 2 Pin Connector configurations, allows passage of Our Enhanced Grip & Extended Strain Relief 2 Pin configurations, as well. About $5 for (8) sets of 8-32 fastener hardware, makes for a professional job of connector flange installation.

So, I set out to combine this assembly with these handy cat litter buckets to build a DIY Solar Backup 12V Power Battery Bucket.

These buckets are of a size that easily handles the weight and dimensions of one of many available sealed AGM batteries used in portable solar powered lights, the bucket walls provide the means of mounting connector assemblies, and the bucket also nicely houses the wiring.

At this point I am making up these 2 Pin connector assemblies via solder joints protected with a couple layers of heat shrink tubing. Pending orders, We will move into manufacturing finished product vs assembly by adjoining 2 pigtails resulting in the proper polarity for this application.

A feature I figure will lend to this combination being even more attractive is providing 2 connections for the possibility of both solar battery charging and power use, simultaneously. This is certainly not the optimum use, as it undermines the charge controller’s ability to accurately ascertain and respond to the battery’s condition. But, at times, it may be necessary in meeting immediate needs.

Solar Capitalist LLC is an Authorized Dealer for Deltran www.batterytender.com and We carry their Solar Power Battery Tender line. These units feature a Deltran charge controller – critical to maintaining optimum battery condition.

We have been using an inexpensive means of supporting Deltran’s 5 Watt, 10 Watt, and 15 Watt Solar Battery Tenders, such that they can be oriented for maximum Sun exposure. Supported on light, inexpensive, plastic saw horses (with the aid of some lengths of 1×2 wood), the setup can be easily carried to a sunny spot, and/or reoriented to be in direct sunlight.

It should be kept in mind that this equipment is “portable”. Thus, it is not meant to be left out in the elements for extended periods of time. Nevertheless, the portability lends to the backup use in emergency situations, such as power outages (also potentially handy for camping, etc.). Clearly, the quick connection to “works in a bucket” aspect lends nicely to portability, as well.

Needless to say, setting up some low voltage lighting, and assemblies for connection to handheld electronics and/or other communication equipment, ahead of time would be another step in the direction of preparedness.

We will be adding these 2 pin connector assemblies to our product line on www.solarcapitalist.com in the near future.

SAE 2 Pin – 10 AWG w/ Red & Black Polarity

by on Mar.03, 2017, under HD Variations

We’ve added 10 AWG 2 pin 12″, 24″, and 60″ assemblies with red & black leads to our product line.

10 AWG facilitates the desired higher current carrying capacity necessary for some applications.

Clearly, customers/installers prefer color coded polarity for certain applications.

Assemblies are available in both polarities to facilitate junctions with combinations of these 3 assembly lengths.

Based on input gained through surveying customers, these lengths are the most desirable starting point for this line of 2 pin connector assemblies.

As established with our existing product line, we refer to red leading to the protected “female” socket side as a “power side” connector, and red leading to the exposed “male” pin as a “load side” connector, with respect to junctions.

We’ve discussed the logic behind these designations at greater length in previous posts, but in a nutshell – you’d want to install a “power side” connector (with red leading to the protected “female” socket side) on the end of a set of leads connected to a power source such as a battery.

Therefore, if you’re making up an assembly for connection to it, for example coming from a solar charge controller, you’d use a “load side” connector with red leading to the exaposed “male” pin.

These assemblies have an enhanced elongated connector body configuration for greater strain relief and ease in manipulation (coupling & uncoupling).

The features of these enhanced connectors are an improvement over shorter configurations used mostly in past automotive applications.  An example would be the SAE 2 Pole Flat connectors for 12 volt trailer hitch applications manufactured by Hopkins ( Part No. 47965 ).

Our Improved Design Connectors are great for Portable Solar Applications, especially PV on Campers, Motor Homes, Travel Trailers, and Boats, for Camping, Hiking, Hunting, Fishing, as well as, Emergency Preparedness.

Shroud design provides greater water resistance, especially installed with shroud edge down, such that it provides a “drip edge”.

Overmold 2 Pin Connector Specification

by on Jan.19, 2017, under Compliance

Extended Shroud 2 Pin Solar Connector

Extended Shroud 2 Pin Solar Connector

We are moving further along in Our efforts to address the emerging business needs of our Customers..  Specifically, we have developed a specification for some of our products gaining significant commercial attention.  This specification is yet another component piece of documentation that addresses commercial customer needs, especially the needs of those commercial enterprises doing business with government agencies or in the international marketplace.

Maintaining the paper trail documenting specified requirements having been met is often critical to qualifying as an approved vendor in today’s marketplace.

We are leveraging on years of previous experience in this business, and having developed the necessary detail oriented approach and follow through.

RoHS, REACH, and Conflict Minerals requirements create even greater need for this detail oriented approach.  Maintaining impeccable files providing a document paper trail with continuity is critical.

Upon researching, we found that there is no specification addressing the SAE 2 Pin overmold connector.  SAE (Society of Automotive Engineers) Specification J928 addresses “Electrical Terminals – Pin and Receptacle Type” and SAE J1239 addresses 4, 5, and 8 pin trailer connectors, but there doesn’t seem to be an SAE specification for the 2 pin overmold configuration.

Seems the 2 pin overmold configuration was sort of a spin off developed in the early ’80’s using the spacing from the SAE 4 pin connector addressed by SAE J1239.  So, technically speaking, the 2 pin configuration is not governed by any SAE standard, but they were developed to be compliant with SAE J928 and J1239.

Certainly, the SAE perspective was toward automotive applications, including: trailer hitch/lighting wiring, onboard mechanisms (such as power windows), and battery maintenance.

The use of this connector in portable solar applications has presented some new circumstances, ranging from higher current carrying capacities to harsher environments (resistance to ultraviolet light becoming desirable).  In application to Portable PV, added strain relief is clearly a benefit, both in terms of durability and ease of manipulation.

In fact, it may be appropriate for a designation more accurate to the configuration be applied to this connector, such as “2 pin solar connector”.

American Made SAE 2 Pin Connector Quality

by on Aug.18, 2015, under USA #1

Imported SAE 2 Pin Extension

We have a customer that has used Our Products in His Application for several years now, and He has undergone some pertinent learning.

Initially, in the interest of economy, He had been purchasing the cheaper SAE 2 Pin assemblies coming from offshore.

As might have been anticipated, the lower quality imported product wasn’t holding up to the constant coupling & uncoupling.

These short SAE 2 Pin connectors lacking the enhanced reinforcement of Our American Made line, often succumb to conductor breakage within the insulation at the back of the connector body.

This occurs because with manipulation, the conductors get bent back and forth and work harden – making them brittle and subject to breakage.

Our American Made SAE 2 Pin Connectors have an Extended Body which adds Reinforcement, and therefore “Strain Relief” which avoids the type failure described above.

The Extended Body of Our American Made SAE 2 Pin Connectors also provides for Enhanced Grip and Ease in Manipulation.

These Features are Especially Appreciated in not only High Use Applications, but Harsh Environments as well.

Consider coupling and uncoupling in Frigid Weather when the materials are not only hard & brittle, but the wearing of gloves may make the Extended Body Much Appreciated.

Beyond the Basic Extended Body SAE 2 Pin Connector We offer with 18 & 16 AWG, We offer an Enhanced Grip Model with 12 AWG.

We also make this Enhanced Grip Model available in a Shrouded Version, which provides Protection over the Junction.

As can be seen, producing and offering SAE 2 Pin Connectors in an Expanded array of Configurations as well as Wire Gauge & Lengths is what We are all about.

It is Our Mission to Provide Ease in Obtaining the SAE 2 Pin Assemblies that Best Meet Our Customer’s Needs & Desires, be it an existing configuration, a variation, or an assembly Engineered to Meet Unique Specifications.

Our Engineering Experience aids Us in understanding and communicating in a Professional Manner, yet with Intention – We Seek Out and Enjoy interaction with Customers Appreciating Our Willingness to Assist in the Development of an Assembly that would meet Specific Needs.

We will Never Forget Those that have extended Patience & Understanding to Us in the Development of Our Niche, and with Intention – We Attend to Passing that Spirit Forward.

Our Expertise developed out of being Educated as an “Hands On” Agricultural Engineer, spending most of career as an Engineer in the Nuclear Power Industry and other heavy Industrial Environments, and then going “small business” in the Battery Maintenance and Portable Solar Industries.

One of Our Delights is coming to Know New Applications We hadn’t even considered – Examples: Fishing Lights, Electronic Game Calls, Tractor Mounted Spray Units…

Note: SAE 2 Pin Connectors are also referred to as 2-prong, 2-pole, 2-way, and flat trailer plugs.  They are often found in the battery maintenance industry (for example: on the output of a battery tender) and in the portable solar charger industry.  A basic version is commonly available from Hopkins Manufacturing as P/N 47965 as they are used in the trailer industry.

We endeavor to bring High Quality Made in the USA SAE 2 Pin Connector Assembly Configurations to the Marketplace.

SAE 2 Pin Connector Pigtails

by on Mar.26, 2015, under Availability

What is an SAE 2 Pin  “connector pigtail”, and how can it be used?

A “connector pigtail” is a connector with a “pigtail” of cord, or leads…

A “connector pigtail” facilitates the replacement of a worn or otherwise faulty connector…

By cutting the existing cord or leads appropriately, the new connector assembly can be connected to the loose ends left by the cut.

Best Practice warrants soldering the conductor connections and the application of heat shrink tubing to re-establish insulation and protection.

Care must be taken to identify the Polarity prior to cutting, as well as making the circuit safe by parting connectors or pulling a fuse.

The Polarity of the Connector is specific: Hot (+) Positive leading to either the Protected “Female” Socket side of the connector or the Exposed Male” Pin side (either being the case with an SAE 2 Pin connector).  Specific insulation color may be indicative – for example, red indicating “Hot (+) Positive”.

Another important aspect is matching the wire gauge.  Existing fuse protection is based on protecting the existing wire gauge.  Slightly heavier would be OK, but smaller would not.

Beyond repairing an existing circuit, Connector Pigtails can also be used to establish a “disconnect point”, when building a circuit.

What is sometimes called a “Connector Whip”, might also prove useful.  This is a Connector assembly with a longer cord or leads – say 5′ (vs the 6″ or 12″ known as “Pigtails”).

Changing Connector assemblies provides the opportunity for upgrading.  We make available more durable configurations employing greater reinforcement for strain relief.  This adds the benefit of being easier to manipulate (connect & disconnect), as well.

As a result of frequent connection & disconnection, the conductors often become brittle and break within their insulation – thus interrupting electrical continuity.  Configurations with added strain relief (reinforcement at the back end of the connector) tend to last longer when frequently coupled & uncoupled.

Connectors “mass produced” offshore and sold at discount automotive stores, generally lack such attributes.  High Quality is immediately evident upon inspection of Connectors manufactured here in the United States to meet real world conditions and service.

We are committed to making an assortment of SAE 2 Pin Connector configurations available with wide range of conductor gauges – manufactured here in the USA, and at reasonable prices.

We do carry a mass produced SAE 2 Pin connector assembly (manufactured offshore) for appropriate application.  Our Customers are therefore able to quickly see by visual comparison, the clear differences in Quality.

DC Connector Terminology

by on Mar.09, 2012, under Terminology

Whenever one choses to delve into a technical topic, it’s worthwhile to begin with a study of pertinent terminology.  Generally speaking, it won’t be long before you start bumping into terms that are key to gaining an understanding.

The handy SAE 2 Pin connector is a great example.  We all had some exposure to basic electrical concepts in our early years, but not everyone has experienced continued exposure throughout their life.

If you were to begin looking for some information on the SAE 2 Pin connector, you’d probable come by it being described as a type of “DC connector”.   Now many are reminded of the terms AC and DC by the name of one of my favorite bands.  Some people might understand that what they access at a household electrical outlet is AC, and maybe even that AC stands for “alternating current”.  I hesitate to think that very many people actually have a firm grasp on just what “alternating current” means, let alone – “DC”, and “direct current”.

I’m not poking fun at anybody.  Many of us are very knowledgeable about areas of technology without any reason to have this particular knowledge.  An engineer, and the son of an electrician (early in his career), I’ve had quite a bit of exposure to electrical concepts throughout my life.

Direct Current (DC) being that which pertains to the topic of SAE 2 Pin connectors, that will be our focus in this discussion.  Any discussion of DC vs. AC is going to involve explaining that the “direct” vs. “alternating” pertains to the direction of the flow of electric charge.  Direct Current (DC) is the flow of electric charge in one direction.  Alternating Current (AC) is the flow of electric charge in both directions, i.e., “alternating” one then the other.

Alternating Current (AC) is what we access at household electrical outlets, but it also describes that which is produced by an Alternator.  An alternator converts mechanical energy (the belt driven rotation) to electrical energy in the form of alternating current.  An electrical device called a rectifier converts alternating current (which periodically reverses direction), to direct current (which flows in only one direction).  A rectifier produces a type of DC characterized by pulsating voltages and currents.  This type of DC current may then be further modified into the type of relatively constant voltage DC characteristically produced by such sources as batteries and solar cells.  There’s a lot of room for further discussion along these lines.  For our purposes, let’s leave it at the above for now.

As stated above, it is Direct Current (DC) that is produced by a battery.  It is direct current that used to charge batteries, as well.  Most electronic systems employ a DC power supply.  It follows then that a “DC Connector” is an electrical connector used in supplying Direct Current (DC) power.  There are numerous standardized DC Connectors with specific dimensions and configuration to prevent accidental connection of incompatable sources and loads.

An important aspect of a connector is its “Pinout” – which describes the function of its contacts (or “pins”).  That function may be Power (“+” positive, or “-” negative/ground), or Signal related (as in the case of a USB connector with “+” Data and “-” Data contacts).

When it came time for battery maintenance industry leader, Deltran, to select a DC Connector for the output of their Battery Tender line – the SAE 2 Pin connector was no doubt the hands-down choice.  Common in the automotive industry, its selection by battery maintenance equipment manufacturers makes sense.

Most peoples’ likely exposure to the SAE 2 Pin connector probably has to do with its use in trailer light systems.  SAE 2 Pin assemblies can often be found in the trailer lighting section of automotive stores.  Hopkins Manufacturing (the name you’re likely to most often see associated with trailer light wiring products), calls these 2 Pole Flat connector assemblies – Product No. 47965.

It was then likely to follow that upon development of Portable Solar Chargers, the SAE 2 Pin connector was to be the choice.  Industry leader, Global Solar, chose the SAE 2 Pin connector for the output of the majority of their SUNLINQ line of portable solar chargers.  In fact, their 6.5W and 12W models feature a 5-piece SAE 2 Pin accessory cable kit.

These two applications give rise to the next topic – “polarity”.  Polarity being which side of a particular connector is “hot” (+) positive, and which side is (-) negative.

In the case of Battery Tenders, the connector polarity is driven by the necessity for it to be the “protected” female side of the SAE 2 Pole connector at the end of the assembly connected to a vehicle battery to be the “hot” (+) positive side.  Therefore, the exposed pin side of the SAE 2 Pin on the end of a Battery Tender output must be “hot” (+) positve.

Portable Solar Chargers are a different situation, since the solar cells are a power source.  Their output connection must therefore be of the polarity which will have the “protected”  female side of the SAE 2 Pin connection being the “hot” (+) positive.  Accessory assemblies must then be of a polarity in which the exposed male pin of the SAE 2 Pin meant to be plugged into the output connection of a portable solar charger must be the “hot” (+) positve.

Anyone connecting leads in circuits such as those discribed above must be carefully mindful of polarity.  There may even be times when it is necessary to use a multi-tester to confirm polarity.  The continuity test function of a multi-tester can be employed to determine which contact (or pin) on the connector at one end of a lead is mapped to (leads to) which contact on the connector at the other end.

Well, we’ve covered quite a few electrical terms and concepts – enough for now.
