Pilz PSENcode non-contact access permission key

The coded safety switch PSENcode key only allows authorised persons to access machine functions and prevents the machine restarting. It is designed as an alternative to the more comprehensive solution with the pushbutton unit PITgatebox and integrated PITreader. A PSENcode key is the symbiosis of Pilz’s PITreader actuator and its non-contact safety switch PSENcode. It enables safe solutions up to PLe and SIL3.

Two applications are possible with the PSENcode key, thanks to its key lock principle. Firstly, if the employee has the key, he or she receives the machine enable that’s tailored to their individual task and can enable operating modes. Secondly, if the key is on the machine, the employee can remove the key, so preventing the machine from starting unintentionally.

The safety switch is used for position monitoring and monitoring the position of guards in accordance with EN 60947-5-3. It comes with integrated evaluation and standard interfaces and is thus open to products from other manufacturers. This makes the coded safety switch suitable for a user’s environment and an upgrade to a plant.

It can be combined with safety device diagnostics which are designed to avoid service callouts and reduce downtimes.

Features of the coded safety switch include: mode of operation: RFID transponder technology (non-magnetic action principle); diagnostic interface: 3 LEDs; designs: narrow, compact or large; outputs: 2 safety outputs; inputs: 2 safety inputs; protection type: IP67/IPK69K; coding of PSENcode for safety gate monitoring: coded, fully coded, uniquely fully coded; and coding of PSENcode for position monitoring: coded.
