Our compact safety relays meet the demands made of machine building applications all over the world. They are used primarily in food, packaging, and assembly handling machines.
Safety relays starting from an overall width of 6 mm
PSRmini relays are the narrowest safety relays available on the market. PSRmini safety relays need up to 70% less space in the control cabinet, without compromising on performance.
Safety relays with a market-standard design
The PSRclassic conventional safety relay range features a large selection of functions and versions. The housing width corresponds to the market standard.
Multifunctional safety relay with up to two adjustable safety functions
With the PSRuni multifunctional safety relay up to two safety functions can be monitored with just one device. The comprehensive coverage of common safety functions enables flexible configuration and adaptation to individual requirements.
As a machine builder, you are familiar with the dynamics and requirements of your market. Functional safety is playing an increasingly significant role. Standards and directives make an important contribution here. With our PSR safety relays, you are able to create new safety concepts that provide many advantages:
