October's sensor of the month: Coded safety switch PSENcode

By: Pilz  06-Dec-2011

Our Sensor of the month series introduces a product highlight from our portfolio every month. In October we are presenting the unique, fully coded version of the coded safety switch PSENcode.

Highest level of manipulation protection, despite the compact design

The unique, fully coded version of the safety sensor PSENcode accepts only a single actuator (key lock principle). As a result, it is impossible to manipulate the switch: The highest level of protection can be achieved in the smallest space for applications up to PL e of EN ISO 3849-1 or SIL 3 of EN/IEC 62061, as well as providing high availability for your plant.

Economical solution

Thanks to non-contact operation, the coded safety switch guarantees a long service life. Integrated evaluation also enables the PSENcode to be connected in series to other sensors, without compromising the safety classification; it also saves on safe inputs on the evaluation device.

Additional benefits of the coded safety switch PSENcode:

  • Flexible installation, as both sensor and actuator support all mounting and approach directions
  • User-friendly diagnostics via double-sided LED display
  • Open to interfaces and products from third-party manufacturers

Recommended product: PSEN cs4.2a/PSEN cs4.1

Order number*: 541201 (cable connection type, 5m)

* The sensor is also available for other connection types.

Just Three Months before

Proactively beginning with risk assessmentMachine builders and users, who until now, relied on EN 954-1 will be forced to reevaluate their existing safety systems and policies. Doing so proactively beginning with risk assessment, they will yield benefits relating to risk reduction and more intelligent solutions for machinery safety.

Safe control solution for stage technology

The total solution (PSSuniversal PLC, standard rotary encoder PSENenco and PAS4000 software blocks) is standard-compliant in accordance with SIL CL 3 and PL e. The control system PSSuniversal PLC and the new dual-channel standard rotary encoder PSENenco are used for this purpose. Stage hoist applications can be safely monitored in the automation system PSS 4000. It's essential to monitor stage elements that are constantly in motion.
