Based off the design pioneered by Anderson in 1953, the two pole SB® connectors set the standard for DC power distribution and battery connections.  SB connectors feature a rugged one piece plastic housing using stainless steel springs to retain the contacts and create the “contact force” that provides extremely low resistance enabling greater electrical efficiency. The SB connectors are also genderless (flip one 180 degrees and they will mate to each other) reducing the customer’s bill of materials and providing greater economies of scale when purchasing. The SB series of connectors range in size from SB50 to the SB350. Each family size offers color-coded, mechanically keyed housings designed to prevent both visually and physically cross-mating devices with different voltages. All the connectors are UL rated to 600 volts so the keys and colors are just identifiers to prevent accidents. Contacts are traditionally Silver plated to minimize electrical resistance while offering supreme durability and reliability.

SB 350

  • Up to 350 mcm (185mm2) Wires
    Allows UL rated currents up to 500 amps
  • Chemical resistant housing option
    Extends temperature range down to -40°C, while offering enhanced UV and chemical resistance
  • Same housings used for wire and busbar contacts
    Enables color-coded mechanically keyed wire to busbar connections


Chemical Resistant

The Chemical Resistant (CR) line of connectors were developed for customers whose applications require robust connector solutions that offer durability against environmental factors that commonly degrade standard products. The housing material offers improved resistance to hydrocarbons and solvents, as well as an extended temperature range. The CR connectors are ideal for a variety of industries that include Automotive, Industrial, and Personal Mobility.  In addition, these housings offer all the benefits of the industry standard Powerpole® products including color and mechanical coding, hot plug capability, and genderless design.  These products are fully intermateable and interchangeable with the standard lines of connectors and accept the same range of contacts.
