SICK Safety switches IN4000 Standard

The IN4000 Standard inductive safety switches are used for determining position and work on a non-contact basis. These safety switches are actuated through metal (e.g., ST37 steel) so that no separate actuator is required. It has a single-channel operating principle: a pulsed input signal is converted to a pulsed output signal and evaluated by the connected safety controller. The response time of the sensors is monitored spatially and chronologically, enabling better prevention against tampering and a high level of safety protection. Their non-contact operating principle enables simple adjustment and mounting as well as providing increased shock and vibration resistance.
