GN 516 compression latches 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 the protective cap.
A 10 mm adjustment within the latch distances A1...A4 can be achieved by the M6 set screw. This covers a clamping range from 1 to 41 mm inclusive.
