Headers, Plugs and Sockets

Plug or receptacle header terminal blocks are PCB, DIN rail, channel, free-hanging, solder or panel mount connection points for securing two or more wires to a circuit, cable or power bus. Mounting features may include board guides, flanges, latches, ejectors, levers, strain reliefs and locks. UL certified and IEC rated terminal blocks are selectable by current and voltage parameters as well as wire gauge, body color, and termination style.
