Installation position

Permissible installation position

Industry 4.0 ready

The switch can communicate in combination with an EUCHNER BR IO-Link Gateway, and sends process and device data to higher-level control systems. Comprehensive diagnostic messages enable rapid and targeted troubleshooting.

Highly coded evaluation

The actuators of a packaging unit must be assigned to the safety switch by a teach-in operation so that they are detected by the system. This unambiguous assignment ensures a particularly high level of protection against tampering. The system thus possesses a high coding level.

The coding is identical for all the actuators in a packaging unit. Actuators from different packaging units are coded differently. Only one actuator from a packaging unit has to be taught-in. All other actuators from the same package can be used without an additional teach-in operation.

The switch detects only taught-in actuators. When an actuator from a new packaging unit is taught-in, the code for actuators from the previous packaging unit is disabled.

Category according to EN 13849-1

Due to two redundantly designed semiconductor outputs (safety outputs) with internal monitoring suitable for:

  • Category 4/PL e according to EN 13849-1

Important: To achieve the stated category according to EN ISO 13849-1, both safety outputs (FO1A and FO1B) must be evaluated.
