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.

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, SAE 2 Pole, SAE 2 Prong, SAE 2 Conductor, Flat 2 Wire Trailer Plug, 12 Volt DC Connector

by on Mar.07, 2015, under Availability, Terminology

An interesting aspect of this connector is that although there are many descriptive terms (2 pin, 2 pole, 2 prong, 2 conductor, 2 wire, flat trailer plug, etc.) used to describe it, there is often much uncertainty with respect to its actual identification.  The “SAE” identifies it as a product of the automotive industry (SAE = Society of Automotive Engineers), but not everyone realizes that.  Some may find their way to one manufacturer’s marketing of this connector at an auto supply store.  Hopkins Manufacturing, widely known for trailer hitch related wiring components, markets this connector with the description “2 pole flat connector” assembly and the product number 47965.  The assembly is a 12″ long extension with red and white insulated 16 AWG conductors.  This product is mass produced outside the U.S., and the quality reflects that in terms of simplicity as well as the occurrence of quality issues.

Clearly, Hopkins avoids the “SAE” designation, as the uncertainty with respect to identification serves their purposes.  Knowing the proper designation (and/or alternate descriptions) enables the searcher to cast a wider net in pursuit of not only sources but assembly variations.

Similarly, the well known producer of Battery Tenders – Deltran Corporation, also avoids using the “SAE” designation.  Deltran’s Battery Tenders include cable assemblies using SAE 2 Pin connectors.

It doesn’t end there – SAE 2 Pin connectors are also widely used for coupling to Portable Solar Chargers.  Here too, the “SAE” designation is left out of the description.  Thus, limiting the users choices in finding alternate sources (or the fabrication) of cable assemblies.

Wikipedia includes information pertinent to this connector in its description of DC connectors:

As stated, the purpose of this Blog is to provide a forum to facilitate discussion of topics pertinent to SAE 2 Pin Connectors.  We welcome our reader’s active participation in these discussions.  Please Comment your observations, questions, and experiences !!!

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.

SAE 2 Pin Defined

by on Feb.08, 2012, under Terminology

As indicated by the “SAE” aspect of this connector’s designation, the specifications for this connector were developed by the Society of Automotive Engineers.  Learning that, we are quick to realize this connector was (at least initially) intended for use in automotive industry applications.   Therefore, the SAE 2 Pin Connector was developed for use in DC (Direct Current) circuits – most often 12 Volt DC.  So in the world of electrical connectors, the SAE 2 Pin Connector would be loosely defined as a type of “DC Connector”.

Further defintion of an SAE 2 Pin might include the description “hermaphrodite” two conductor DC connector.  The term “hermaphrodite” is applicable because each connector includes both “male” and “female” components – an exposed “male” pin, and a protected “female” socket.

An SAE 2 Pin Connector is often seen on the output of battery maintenance equipment, such as the industry leader – Deltran Battery Tenders.

Therefore, the associated accessory assemblies are outfitted with an SAE 2 Pin connector of the polarity necessary to carry out the intended function.  For example, a Deltran Battery Tender “Quick Connect” assembly, to which a Battery Tender output can be coupled to maintain a motorcycle 12V battery’s charge during periods of little or no use.

Thus far in this post, we have focused on the term “SAE 2 Pin”, but this connector is often given other names – SAE 2 Prong, SAE 2 Pole, SAE 2 Conductor, 2 Pole Flat Trailer Connector, etc.  It’s pretty clear that “SAE 2 Pin’ is indeed the appropriate terminology, based on the connector’s specification developer (SAE – Society of Automotive Engineers) and this term’s consistant use.

 

The SAE 2 Pin connector has surfaced as the predominant choice in the portable solar charger industry, as well.  For example, Global Solar’s SUNLINQ 6.5 and 12 Watt portable solar chargers have an SAE 2 Pin connector on their output cable.  The associated accessory kit consists of 5 cable assemblies with SAE 2 Pin connectors.  The polarity of these assemblies is specific to their use coupled to the output of the 6.5W or 12W portable solar charger.

Deltran’s 5W, 10W & 15W Solar Panel powered Battery Tenders feature and SAE 2 Pin output, as well.

The predominance of the SAE 2 Pin connector in 12 Volt DC applications is prompting a growing assortment of cable assemblies and adapters.  For example, SAE 2 Pin x COAX adapters.

SAE 2 Pin connectors are being made available in a wider range of wire gauge, as well.  Heavier AWG leads are facilitating greater current carrying capacities, and thereby use in higher current flow applications.
