Non-contact safety switches
IN4000 Standard

Safe, non-contact position monitoring

Your Benefits

  • Fast diagnostics via LED status indicator
  • Cascadability of up to 9 sensors saves costs
  • Long service life due to durable and low-maintenance design
  • Just one safety switch in conjunction with a suitable safety module makes it possible to solve applications up to PL e and Cat. 4 (EN ISO 13849)
  • The devices are easy to clean, making them suitable for contaminated areas or environments with strict hygiene standards


Safe, non-contact 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.
