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.

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.
