Two-pole power connectors

28 April 2021 Interconnection

Based on the design pioneered by Anderson Power Products 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 which enables greater electrical efficiency. The connectors are also genderless (flip one 180 degrees and they will mate with 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 the SB50 to the SB350. Each family size offers colour-coded, mechanically keyed housings designed to both visually and physically prevent cross-mating of devices with different voltages. All the connectors are UL rated to 600 V so the keys and colours are just identifiers to prevent accidents. Contacts are traditionally silver-plated to minimise electrical resistance while offering enhanced durability and reliability.

Highlights of the SB connector range include the following:

SB 50

• Low-resistance silver- or tin-plated copper contacts – allows UL rated currents up to 120 A.

• UL rated for hot plugging up to 50 A – great for battery or other applications where the ability to interrupt circuits is required.

• Chemical resistant housings available.

• Wire, PCB and busbar contacts – allows one connection system to meet multiple needs.

SB 120

• New extended range contacts expand wire size up to #1 AWG (42,4 mm2) – allows UL rated currents up to 240 A.

• Chemical resistant housing option – extends temperature range down to -40°C, while offering enhanced UV and chemical resistance.

• Panel mounting grooves – with the use of mounting clamps, can be easily mounted through panels.

SB 175

• Standard housing uses up to 1/0 (50 mm2) wire and allows currents up to 280 A.

• SB 2/0 housing allows use of 2/0&nbap;(70 mm2) wire and handles up to 340 A.

• Same external dimensions as standard SB 175 and completely inter-mateable.

• UL rated for hot plugging up to 100 A.

• Chemical resistant housing option – extends temperature range down to -40°C, while offering enhanced UV and chemical resistance.

• Wire and busbar contacts – allows one connection system to meet multiple application needs.

SB 350

• Up to 350 MCM (185 mm2) wires – allows UL rated currents up to 500 A.

• 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 colour coded, mechanically keyed wire-to-busbar connections.
