Anderson Power 6331G7
SB 50 Connectors
Product Overview
The SB 50 connectors, building on the design pioneered by Anderson in 1953, set the standard for DC power distribution and battery connections. These two-pole connectors feature a one-piece plastic housing with stainless steel springs to secure low-resistance contacts. They accommodate wire sizes from 16 to 6 AWG (1.5 to 16 mm) within the smallest SB series housings. Key benefits 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 ideal for interruptible circuits, and versatile connection options with wire, PCB, and busbar contacts.
