The Binder bayonet connectors of protection type IP40 have a cable opening that comes in two sizes. The bayonet locking protects the plug during mechanical stress and ensures the contact connection. It works with a rotation lock, whereby both connector parts are inserted into each other and the bayonet ring is subsequently turned into the locked position. The cable gland with integrated strain relief ensures that tensile forces applied to the cable do not disconnect the connection plug. The compact bayonet connectors with a diameter of 12mm are available as a cable connector or panel mount connector.
