New All-in-one Safety Gate Switch & Interlock

Supplier: Pilz Safe Automation

Pilz is introducing an innovative interlock with a non-contact transponder for the switching function and an electromagnet to hold the gate closed.


Pilz Australia is launching the new PSENslock device that combines the functions of a safety gate monitoring switch and interlock in one compact, robust unit.

Suitable for mounting directly on 45mm extruded aluminium profiles, the PSENslock is designed for applications up to SIL3 (safety integrity level 3) in accordance with EN/IEC 62061, and Category 4 in accordance with EN 954-1. Sealed to IP67, it can be used on a wide variety of machinery across a diverse range of industries.

The PSENslock holds the gate closed by means of a long-life, maintenance-free electromagnet that achieves a holding force of 500N while drawing only 4.8W from a 24V DC supply. Thanks to the non-mechanical locking technology, the switch/lock and actuator can tolerate a maximum horizontal and vertical misalignment of 5mm.

Proven non-contact, coded transponder technology ensures that the safety switch function is virtually impossible to manipulate, while also ensuring a long life when used on guards that are opened frequently during normal operation of the machinery.

Double-sided, high-brightness LEDs aid troubleshooting and enable the PSENslock to be mounted on left- or right-hinged guards. An M12 connector helps to make the unit quick and easy to install on the machine or to replace in the event of damage occurring.

Dimensions are 122 x 45 x 44mm for the switch/locking component and 138 x 52 x 24mm for the actuator. The PSENslock can be readily mounted on aluminium profiles for hinged guards, or Pilz can supply optional brackets for use on folding or sliding gates.
