Tamper-proof, wear-free access security
Non-contact transponder-coded safety sensors are an excellent option for monitoring protective doors, gates and guards. One of their outstanding features is that they are able to uniquely identify passive RFID transponders, which ensures high coding levels and therefore high protection against manipulation.
The BID R03K safety sensor is an ideal solution in particularly dirty and dusty environments. It has a large response range and is also insensitive to vibrations, a good solution when doors sag or are mis-aligned. For particularly strong vibrations, a variant with an optional holding magnet is available.
The integrated safe evaluation electronics as well as the OSSD output stage mean that the devices can be used in in applications up to PLe or SIL 3 (ISO EN 13849 and EN IEC 62061). Since the passive RFID transponder is uniquely identified by the sensor, high coding levels and high bypass protection can be implemented (EN ISO 14119).
