Safety locking devices

Product selector

The door stays closed!

Safety locking devices keep protective doors securely locked and thereby prevent the inadmissible access of people until the guarded machine no longer poses a danger. Not until there is no longer a danger to the machine or to the workers is access released by an electric signal. With their robust design, all Leuze electronic Safety Switches and Locking Devices are designed for rough industrial applications.

Tamperproof through RFID technology

The robust L300 safety locking devices for safety applications up to SIL 3 / PL e are used to guard large safety doors or sliding gates as well as very large machines that have stopping times. The actuator is detected electronically by means of RFID technology. Through millions of different encodings, the actuators achieve a high encoding level acc. to EN ISO 14119 and thereby reliably prevent possible attempts at tampering. The L300 series is designed for use under rough environmental conditions.

  • RFID actuator for maximum protection against tampering
  • Robust design with 7,500 N locking force and degree of protection IP 67 / IP 69K for use under rough environmental conditions and under extreme stress
  • 5-LED display for simple status overview
  • Emergency unlock function (ergonomically optimized panic button) for manually opening the protective devices in the event of an emergency
