GN 120.4 Electromechanical Locking Systems Plastic, for Cam Latches

If the latch arm is moved to the closed position via the rotation limited to 90°, the spring-loaded locking catch snaps forward to prevent reopening of the cam latch.

In the closed position, the presence of the latch arm is detected by the latch arm check, and a high signal is output at the latch arm check output (pin 4) if a connection is also present between the additional contact pins 5 and 6. For example, this can take the form of a simple wire bridge or a door position check.

To release the latch again, a high signal is applied to control input pin 4, causing the locking catch to be withdrawn electromechanically. In the event of a power failure or system fault, the locking catch can be pushed back via the manual emergency release. The emergency release is designed to allow the fastening of a Bowden cable.

When the high signal at control input pin 4 falls away, the locking catch is released by the electromechanical mechanism, allowing the spring to push it forward again into the initial position.
