SAE 2 Pin Max Strain Relief

SAE 2 Pin Max Strain Relief & Grip

Researching the use of SAE 2 Pin connector cable assemblies to power and charge surveying equipment indicates there are a limited number of choices.

Specifically, the Topcon Model RE-S1 only lists 2 associated assemblies P/N 14-008022-01 and 14-008025-01

Limited choices, and that this specialized field is driving some high prices, spells opportunity.

We can see where a greater number of cable assembly choices, as well as, reasonable pricing, are values we can bring to this application.

Frequent use makes higher quality SAE 2 Pin connector configurations with enhanced strain relief and grip the certain choice in the field.

Durability is no doubt required in this application, and heavier gauge (although maybe not required for current carrying) often contributes higher durability.

Topcon P/N 14-008022-01 seems to be an SAE 2 Pin 6 foot extension (unknown AWG).

Topcon P/N 14-008025-01 seems to be an SAE 2 Pin “Quick Connect” type assembly with Alligator Clips (about 18″ long, unfused, and unknown AWG)

Found another supplier offering 2 different Fused 6 foot “Quick Connect” type assemblies with (unknown diameter) ring terminals (unknown AWG), one with an enhanced configuration SAE 2 Pin, and the other with a shrouded enhanced configuration. Both carried more reasonable pricing, but still priced higher than we see necessary.

We assemble a wide assortment of High Quality Configurations meeting specific Customer needs at a reasonable price.

We’ll take the time to discuss and understand the specifics of your application and how You would like to address them.

A combination of a couple assemblies is sometimes the answer, and we can even supply You with a zipper bag to keep them protected and neatly stored.

We’ve been in business for 10 years, and we’ve developed a knack for ascertaining details and pleasing our customers.

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 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 in the near future.

SAE 2 Pin Today

by on Apr.26, 2016, under Application

We continue to learn of increasing application of our SAE 2 Pin connector assemblies. Providing SAE 2 Pin connectors with heavier gauge wire as well as enhanced connector bodies, has had them see new applications. The heavier gauge wire offerings facilitate applications involving greater current flow. The enhanced connector bodies provide strain relief as well as grip for ease in manipulation. Clearly, the Quality of Our Made in America products is far superior to the mass produced assemblies coming in from other countries.

Being found continues to be sort of a challenge, as not everyone is aware of the “SAE 2 Pin” designation. By virtue of an assortment of keywords, we are sometimes found via other related terms or phrases. In addition to our ecommerce web site at , we strive to raise the level of awareness with technical discussions on both of our blog sites: and

Although we initially targeted motorcyclists and portable solar powers enthusiasts, we have widened that focus to include many other realms. Some of those realms precipitate very little, but then others seem to produce appreciated attention.

Interaction on several forums has driven up some attention.

For example, on this Vanagon enthusiast forum…

Seeing the need for replacement SAE 2 Pin Caps, developing a mold, producing and marketing the “hard to find” caps, has gained us sought after attention.

Amateur (or Ham) Radio is one of the realms we attempted to pursue, but it seems to only have produced limited results. Here is one of the offerings targeting this application:

We’ve even developed an SAE 2 pin assembly to specially address Motorola radio application involving a power supply with “switch leg”.

Heavier Duty application prompted us to develop Shrouded SAE 2 Pin connection pigtails. Our Shrouded SAE 2 Pin Junction components both feature enhanced strain relief and grip and 12” Black Cord with 12 AWG conductors. When your application involves rough duty (dirt, dust, moisture, heavier current flow, and frequent or rough manipulation – wearing gloves, for example), these high Quality connector assemblies may very well be what you need!

Electronic Coyote Caller w/ SAE 2 Pin

by on May.19, 2015, under Application

Our 1st Electronic Coyote Caller – a Business Project, as well as a Hunting Project prompted by the skyrocketing Coyote population in Georgia which is impacting the survival rate of Young Deer & Turkeys – Big Time !!!

Research online quickly provided guidance on components as well as calling.  Within minutes We had a loudspeaker and amplifier ordered on (Radio Shack was recommended, but seems to be tapped out and headed for bankruptcy).

Being Cat Lovers with 3 Rescues, We go through buckets of Kitty Litter. We save the empty litter buckets because We find them very handy & efficient for storage (they’re rectangular, stackable, have lids and a carry handle, etc.).

I was immediately envisioning use of a kitty litter bucket in the assembly of a electronic coyote calling setup.

Coyote Caller Components

A sealed 12 Volt AGM Battery (We have these on hand for other projects – generally Solar) mounted in the bottom of the bucket would provide weight for stability as well as Power.

A Fused Battery Pigtail with SAE 2 Pin Connector (available from US) will not only provide for access to Power, but for connection to a Battery Tender for recharging as well.

An SAE 2 Pin pigtail with 18 AWG leads (available from US) was installed on the power leads of the amplifier.  The leads on the amplifier are lighter, but this combination lends itself well to ease in coupling & uncoupling, and therefore durability.

Same with the Speaker connection wiring – installed using an SAE 2 Pin Junction with 18 AWG leads.  This facilitates easy disconnection for disassembly.

Part of the Beauty of the Bucket is that it not only facilitates assembly and protects the components – out of sight, but keeps all the wiring & connections contained.

The amplifier was mounted on the underside of the “trap door” lid to facilitate easy access to volume control during operation.

(6) Fastener Assy’s for Speaker

(4) Fastener Assy’s for Amplifier

(1) Green, (1) Brown, (1) Gray, (1) Black spray paint (to facilitate camouflage painting using tree limbs, pine boughs, etc.)

*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.
