The SICK T4000 Direct Series Safety Switch is a monitoring system designed for use with applications where high level protections against tampering is required. The integrated evaluation unit can be directly connected to a safety controller, with the safety switch only released if a valid actuator is sensed within the 19mm response range. With the multicoded switch variant, any valid actuator can be located within the sensing range. With the unique coded variant, only individually coded actuators with the matching code will be located within that range, which also increases tampering protections. The T4000 Direct Series features a high level of machine availability due to tolerance for door misalignment, shocks and vibrations. Units can be cascaded with up to 20 other switches, all with LED status indicators. This makes installation and servicing simple and convenient.

Applications

  • Monitoring of safety doors and removable guards
  • Applications requiring a high standard of hygiene
  • Applications where precise guidance of the safety door is not possible
  • Machinery and systems where vibrations occur
