Based on the design pioneered by Anderson in 1953, the two-pole SB 50 connectors set the standard for DC power distribution and battery connections. They feature a one-piece plastic housing using stainless steel springs to hold low-resistance contacts in place. Wire sizes from 16 to 6 AWG (1.5 to 13.3 mm) are accommodated. Key advantages include low resistance silver or tin-plated copper contacts allowing UL-rated currents up to 120 amps, UL rating for hot plugging up to 50 amps (great for battery applications), and a versatile connection system with wire, PCB, and busbar contacts.
