The SICK MLP1 Series Safety Switch features a magnetic locking function, ideal for applications that require process protection in addition to the safety function. This RFID safety switch monitors its semiconductor outputs itself, enabling a high level of safety for door monitoring. In combination with the strong electromagnet, these two low-wear technologies ensures high door offset tolerance. Variants meet Pl e and SIL 3 performance levels. The integrated mounting styles along with the flat actuators of the MLP1 Series offer easy assembly into machine systems. Safe series connection configurable.

Applications

  • Protection of people in applications which do not involve overrun movements
  • Process protection for automated production systems
  • Applications where precise guidance of the protective door is not permitted
