• Marking: screen printed + serial no. for traceability.

Example of application

1. Key free = sensor disabled. AUX2 output sends voltage (e.g. Unlock command). The operator takes the key and enters the zone.
2. Key trapped = sensor activated. AUX2 output cuts the voltage (e.g. Lock command). The operator cannot enter; otherwise the sensor will be triggered, cutting off power to the machine.

Integrated auto-control

This product range integrates an auto-control device and dry contacts for use without an external control box (Pl d/SIL 2). Shock resistance: 10G.
