Switches with separate actuator

Owing to their robust housings and wide variety of installation options, the S20 and S200 series safety switches with separate actuator can be used universally. They have five different approach directions for the actuator. Thanks to the funnel-shaped insertion opening, the actuator is centered and the reliability in operation increased. Different contact configurations, connection via cable or connector and a broad range of actuators offer the right solution for your application.

Advantages for you

  • Low-cost solutions: for monitoring doors and flaps
  • Easy integration in safety circuit: All devices can easily be integrated in a safety circuit through positive-opening contacts
  • Easy adaptation to different installation situations: With 5 actuator approach directions
  • Avoidance of unwanted machine downtimes: Through generously dimensioned actuator play in the actuator head


A wide range of actuators ensures that appropriate installation options are always available for your machine or system. For all actuators, the switches have generously dimensioned play of up to 4.5 mm in the actuator head. As a result, slight movements of the protective device do not lead to unwanted machine downtimes.
