Würth Elektronik WR-WTB Connectors is a wire-to-board connector system that offers an ideal choice to electrically and mechanically link wires to a PCB. Crimp technology is ideal when users need a secure and easily reparable connection. In crimping, a metal sleeve is secured to a conductor by mechanically crimping the sleeve. The conductor is crimped in two places – on the wire and on the insulator to provide additional resistance to mechanical stress.
