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.

2 Way Connector as an Alternate Designation for SAE 2 Pin

by on May.07, 2016, under Terminology

Clearly, there are a large number of people who don’t even know these particular designations.

We have been banking on the “SAE 2 Pin” designation, as we feel this automotive designation is most appropriate.

In the interest of capturing the attention of a greater number of seekers, we are keenly attentive to what words others might use in a search.

Somehow “2 way” doesn’t seem all that descriptive, but nevertheless it seems to have caught on with at least a few manufacturers, suppliers, and seekers.

Furthermore, it seems ironic (at least to US – focused on “Made in USA”) that a product manufactured outside the US should become the most prevalent found via an internet search. The Hopkins Manufacturing product 47965 labeled a “2 Pole Flat” connector assembly is found in the towing or trailer equipment area of many discount automotive stores.

Hopkins 2 Pole Flat 47965

Hopkins Product 47965

In our experience (as discussed in previous posts), we have come upon such phrases as “2 prong”, “2 pole”, “2 conductor”, “flat trailer connector”, “12 volt dc connector” being used, as well.

It’s somewhat puzzling to US that the manufacturers of a product marketed and sold in “automotive” stores would chose designations other than that of SAE (Society of Automotive Engineers). Maybe the SAE has rights to that specific designation, and that precludes use of the designation? It wouldn’t seem so, considering the connector design itself is used and simply labeled with an alternate designation.

Without a doubt, what matters is what gets the seeker to that which he or she seeks.

SAE 2 Pin Connector Commercial Application

by on Jan.23, 2015, under Availability

Solar Capitalist LLC www.solarcapitalist.com and Bohemian Biker LLC www.bohemianbiker.com are Patriotic American Citizen Owned & Operated Family Business ventures, established in 2008.  We continue to grow Our Product Line in response to Customer desires, and strive to create positive Customer experiences with Our business processes.  This SAE 2 Pin blog is one of the means by which We attempt to capture the attention of those seeking knowledge with respect to, or a Customer oriented source for Top Quality SAE 2 Pin Connectors.

Over the past 7 years, We have grown from a business addressing the needs of individual do-it-yourself Customers, to a business working hand-in-hand with other businesses – making SAE 2 Pin Connectors available in a range of wire gauge and assembly lengths has become Our forte.

We’ve leveraged the needs of businesses seeking large quantities of SAE 2 Pin assemblies, into an opportunity for individuals to obtain SAE 2 Pin assemblies to meet their needs.  Often, the order size of a commercial customer makes production feasible – and thereby precipitates the availability to those requiring even single assemblies.

Customer requirements have also driven Us to widen Our services to include custom assembly to meet application specific needs.  For example, making soldered/heat shrink protected connections.

We are ever vigilant for opportunities to expand Our Product Line, and provide Services that are desired & appreciated by Our Customers.  Often, a product is the culmination of a process involving interaction throughout the development & production processes.

Applications have been encountered that stretch the use of SAE 2 Pin Connectors beyond those of the past, and in some cases – features have been added to facilitate such application.

Engineering background developed during many years spent in a long list of field, residential, commercial and industrial environments have enabled Us to wade through the wide range of specifications that We have encountered.

We have ventured into fields & applications far beyond those We initially set out to address.  This 12 Volt DC Connector is often encountered as a Hopkins Trailer Connector P/N 47965 and sometimes called a 2 pole flat connector and used as a Quick Connect or Disconnect.  What started with motorcycle applications, battery tenders, and portable solar chargers, has transitioned to – what applications are yet to be found for the SAE 2 Pin Connector?

Even more important is an intention toward Customer Focus.  Specific Customer needs & desires are seen as an Opportunity.

Customer inquiries are Always Appreciated, and We remain Ready & Willing to address Yours – Call Us at 302-562-1706

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 Configurations

by on Feb.04, 2012, under Configurations

 

SAE 2 Pin configurations range from the basic…

 

 

to those with added strain relief…

 

 

Connectors with enhanced strain relief provide the added benefit of being a little easier to manipulate when coupling and uncoupling.

Raised bars on the flat sides of these connectors make them easier to grip when coupling and uncoupling.

Another configuration difference see above is separated leads (of different colors) vs. Black SPT-1 cord.
