Koşul
The task here is to monitor high speed doors with a safety switch. To avoid unnecessary loss of time, the safety switch should enable the next step before the door reaches the end stop.

Geri dönüşüm
Instead of a mechanical safety switch, an electronic fail-safe sensor type GM701S is used here. Advantage: it does not need a special coded target for a reliable switching. Using a longer target the safe state is detected well before reaching the end position. The subsequent clamping processes are already started when shutting the gate.

By means of a simple design feature the process cycle time was reduced by three seconds - while maintaining the degree of safety. This means a greater productivity in terms of quantities as compared to the old detection system that uses mechanical safety switches.
