Safety locking devices

Your Benefits

  • Benefit from the high level of manipulation protection through the use of RFID technology when monitoring the actuator
  • Take advantage of discreet integration into the machine design thanks to the innovative mounting concept
  • Increase the availability of your machine thanks to the high door offset tolerance
  • Save time and money thanks to very simple series connection and the low-wear and low-maintenance design


The MLP1 safety switch featuring a magnetic locking function is the efficient solution for applications that require process protection in addition to the safety function. The transponder safety switch monitors its semiconductor outputs itself, thus offering maximum safety for door monitoring. What’s more, a strong electromagnet ensures that the protective door stays closed and the production process is not interrupted. The combination of these two low-wear technologies provides high door offset tolerance and increases the availability of the machine. The innovative mounting concept and flat actuators of the MLP1 enable optimum integration into machine designs.
