Leuze NG series RFID-enabled safety interlock switches

The NG series RFID-enabled safety interlock switches offer protection ratings of IP67 and IP69K with a locking force of 7500 N. The system can hold unlocked doors in position with a force of approximately 30 N and can prevent the door from being opened by vibrations or gusts of wind. They are best suited to washdown environments where particular attention is required for cleanliness and hygiene.

The series safety interlock switches have the choice of two different activation modes for the safety outputs: Mode 1 (active with guard closed and locked for machines with inertia) and Mode 2 (active with guard closed and unlocked for machines without inertia).

The digitally coded actuators are suitable for use in safety applications up to SIL3/PLe, with a single device for each protection. Versions are available with a lock device, an emergency release pushbutton or both.
