Pilz PSENslock safety gate switch and interlock

Tuesday, 09 June, 2009 | Supplied by: Pilz Australia Industrial Automation LP

Pilz has introduced a gate switch with an interlock with a non-contact transponder for the switching function and an electromagnet to hold the gate closed.

The PSENslock device combines the functions of a safety gate monitoring switch and interlock in one compact, robust unit. Suitable for mounting directly on 45 mm 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 EN954-1.

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 500 N while drawing only 4.8 W from a 24 VDC supply.

Due to the nonmechanical locking technology, the switch/lock and actuator can tolerate a maximum horizontal and vertical misalignment of 5 mm.

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.

Double-sided, high-brightness LEDs aid troubleshooting and enable the PSENslock to be mounted on left- or right-hinged guards.

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