Anderson Powerpole

Some of Anderson's earlier patents have expired, thus other manufacturers have released plug-compatible connectors, such as "AMP Power Series" by Tyco / TE Connectivity, Sermos, Lightspeed.[2]

The Powerpole connector was designed and patented by "Albert & J M Anderson Mfg Comp", then more recently by "Anderson Power Products".

Different keying for each colour in the SB50 series. Note that black and grey are keyed the same making them interchangeable.

For the larger multipole design, which is available in up to 700 A sizes, each color is physically keyed so as to mate only with a like colored connector, and Anderson published a list of recommended voltage for each color:

• Model railroad uses all of the above colors for various purposes.[14]

Many companies in the amateur astronomy space have adopted Powerpole connectors, as a large number of astronomical devices use 12-volts, and Powerpole connectors offer a low cost and easy solution to make adaptors, extensions, and distribution panels. [19]

The Powerpole connector has been adopted by many segments of the Amateur Radio (Ham Radio) community as their standard 12-volt DC power connector for everything from radios to DC power sources to accessories.[12] Two notable groups are Amateur Radio Emergency Service (ARES) and Radio Amateur Civil Emergency Service (RACES).[11] Standardization allows equipment owned by different hams to be used together without needing adapters in emergencies, at public service events, at field day, during contests, when borrowing equipment, etc.

The Anderson Powerpole connector is more expensive than the older de facto standards of the two-wire trailer plug and the Molex connector, but provides a more reliable electrical connection (both mechanically and electrically), and is easier to adapt to a wider range of wire gauges.[20] Another advantage over the older trailer or Molex connectors is the Powerpole's superior ratings to withstand 100,000 no-load insertions and 250 hot-plugs at full load. The specific hermaphroditic nature of the powerpoles is a significant advantage since batteries can be both a power source or a power sink, a power supply can be connected to a radio and/or a battery, and multiple batteries, radios, and/or redundant power sources can be connected in parallel using the same power distribution panels. Connectors in which non-hermaphroditic contacts are arranged in a hermaphroditic arrangement (such as bullet connectors used in low end solar equipment) can be electrically incompatible (reverse polarity damages equipment) and non-hermaphroditic connectors can be mechanically incompatible with each other (won't mate).

Many pieces of amateur radio equipment run on 12-volt DC automotive voltage, which is also called 13.8-volt DC. The voltage delivered by a lead–acid battery with six-cells used as an automotive battery will vary depending on various electrical loads in a vehicle. Without loads the battery will float from 11.7 to 12.8 volts, and while charging from an alternator the voltage will increase to 13.8–14.4 volts DC.

For use in amateur radio, the community has adopted a standard color code, polarity, and specific physical arrangement for assembling pairs of Powerpole connectors. One red and one black powerpole housing can be physically arranged in 4 topologically different mechanical orientations (red left, red right, red top, red bottom - when viewed from contact side with tongue up), 2 of which are mechanically incompatible (connectors won't mate with ARES) and 1 is electrically incompatible (will mate but reverse polarity) with the ARES standard; there are also additional unusual configurations in which one housing is rotated 90 degrees. The standard is red positive and black negative. When viewed from the contact side, a mnemonic for remembering the arrangement is: "Red [on] Right — Tongue [on] Top" (note the first letter alliteration).

West Mountain Radio, a major amateur radio supplier, has had a few 24 V DC products in their catalog for over a decade. They incorporate a 24 volt standard that has the orange body as +24 volts. An orange and black pair would be +24 volts on the orange and ground on the black.

In model railways, the NTRAK Modular Railroading Society adopted the Powerpole PP30 connector as a recommend practice in 2005. and as a standard in 2011. The use of the older Cinch-Jones connector has been deprecated, but is still permitted on legacy modules. However, the owner of a module with Cinch-Jones plugs is now required to provide adapter cables to the newer standard.[13] North Raleigh Model Railroad Club (NRMRC) also uses Anderson Powerpole connectors.[14] The Free-mo modular standard adopted Powerpole as the new connector standard as of 1 July 2015, with a one-year transition period to convert existing Jones connectors.[21]

The connectors are used by some robot builders, including the FIRST Robotics Competition and R2-D2 Builders Club.[15][16]

The Powerpole connectors are used by radio control (R/C) model hobbyist clubs.[2] They may be known as "SB" connectors or "Sermos" connectors with the suppliers in that community.

Some buildings including data centers are increasingly designed for 380 V DC power distribution, as a way of improving electrical efficiency.[22] DC power distribution has resulted in the need to standardize a Low Voltage (LV) connector with an integral ground conductor, which is safe for use by untrained personnel. The tendency of DC connectors to spark when disconnected from an inductive load requires the connector's insulating housing to contain the plasma arc, in addition to normal requirements such as preventing accidental finger contact. Examples of such connectors are the Anderson Powerpole Pak connectors[23] and the SDG (Saf-D-Grid) connector,[24] designed with the form factor of an IEC C15 connector.
