Fail-safe sensor

The GG851S fail-safe inductive sensor from ifm electronic simplifies safety-related applications simply by operating normally closed. The safestate, with the outputs high, is given when the target is not present, i.e.

outside the 10mm enable zone, in the area known as the safe switch-off zone. If a metal object is in the enable zone, the outputs are switched on. It also has a wider operating voltage than earlier versions, allowing operation down to 12V DC.

The GG851S sensor has two OSSD outputs for connection to a safety relay or PLC. The diagnosis of the different operating states is made via LEDs. No special target is required and the GG851S is fully flush mountable. The fail-safe sensor is certified to ISO 13849-1 PL d, IEC 61508 SIL 2 and IEC 62061 SIL cl2.
