The SRF (Safety RFID) is a non-contact safety sensor, that monitors moveable safety guards, such as doors, flaps and hoods.

With its innovative diagnostic system, the SRF makes safety circuits suitable for Industry 4.0.
The system provides a multitude of diagnostic data of each sensor, even in a series connection, to support smart production. Diagnostic data is fed into the machine control system via IO-Link or alternatively displayed on a smartphone by way of NFC technology. In this way, 20 different diagnostic information of each sensor can be retrieved and made available. This diagnostic data delivers cost-effective predictive maintenance in a simple way. Through its advanced fault recognition capability, costly machine shutdowns can be prevented.
This way, your machinery and plant will work even more efficiently!
