GN 516

Rotary clamping latches

The rotary clamping latches GN 516 have a closing mechanism which transfers the rotary movement of the operating element (key) into a 90° turn and then into a 6 mm linear stroke.

This mechanism is designed for common applications such as making a tight and vibration-proof interlock in the end position (retaining position) in connection with an elastic element (door / casing seal).

22 latches with different cranks will cover latch distances (retaining zones) of between 17 and 63 mm. If the measured retaining position lies between two latch distances A, the next smaller value must be selected.

The rotary clamping latches GN 516 are supplied with loosely enclosed latch.

1. Latch in starting position.

2. The first 90° turn of the actuator / key moves the latch into the usual locking position.

3. Turning the actuator further by another 90° will lift the latch in linear direction by 6 mm, pulling the door leaf against the frame or the seal and generating a vibration-proof lock.
