Pilz Australia are introducing an innovative interlock with a non-contact transponder for the switching function, and an electromagnet to hold the gate closed.
Pilz Australia are launching the new PSENslock device that combines the functions of a safety gate monitoring switch and interlock in one compact 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, the PSENslock can be used on a variety of machinery across a 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. Due to the non-mechanical locking technology, the switch/lock and actuator can tolerate a maximum horizontal and vertical misalignment of 5mm.
The non-contact, coded transponder technology of the PSENslock ensures that the safety switch function is 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 any damage.
Dimensions of the PSENslock 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. Pilz Australia also supply optional brackets for use on folding or sliding gates.
