SB 50 Connectors
Product Overview
Building on the pioneering design from 1953, Anderson SB 50 connectors are the industry standard for DC power distribution and battery connections. These two-pole connectors feature a robust one-piece plastic housing secured by stainless steel springs, ensuring low-resistance contact. Designed to accommodate wire sizes from 16 to 6 AWG (1.5 to 13.3 mm), the SB 50 series offers versatility for various applications. Key advantages include low resistance silver or tin-plated copper contacts enabling UL-rated currents up to 120 amps, and UL rating for hot-plugging up to 50 amps, ideal for circuits requiring interruption. The availability of wire, PCB, and busbar contacts allows for a unified connection system across multiple needs.
