The SB-50 Connector is a 2-pole, genderless high-current DC connector widely used for battery connections, UPS systems, forklifts, electric vehicles, solar energy systems, chargers, and industrial power distribution. Its genderless design means identical housings mate together, simplifying installation and reducing wiring errors. SB-50 connectors are designed for reliable, low-resistance DC power transfer and are available with silver- or tin-plated copper contacts.
