Inductive safety switch for position monitoring

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.

At a glance
  • One clocked safety output for direct connection of sensors to a safety controller
  • IP67 or IP69K enclosure rating
  • Response range up to 15 mm
  • LED status indicator
  • Up to performance level PL e (EN ISO 13849)
  • Safe series connection of sensors possible
