GN 1150 cam latches are intended for use in hygienic areas and meet hygiene requirements on the operating side. The locking mechanism is protected by two seals. At the same time, the high surface quality (Ra < 0.8 µm) and dead-space-free mounting prevent dirt from adhering and facilitate cleaning.
The latches create a secure closure by rotating a maximum of 90°, which positions the latch arm in the locked position behind the frame. Slanted surfaces on the latch arm ensure smooth positioning. Latch arms are available with different bend angles to cover a latch arm distance A from 6 to 28 mm.
The mounting holes in the housing must be at a right angle, free of burrs and without a chamfer. This ensures that the sealing rings will function properly. GN 1150 latches are supplied with loosely enclosed latch arm.

For installation, set a bore diameter in the door, cover or hatch as shown in the outline drawing below. The lock housing is inserted into the installation bore from the front and secured from the back with the mounting nut. Then the latch bar is secured with the hex head screw. In series production, the required installation bore in the door leaf is usually created by punching or laser cutting. The installation bore diameter can also be created by drilling or milling as shown in the outline drawings. The sheet metal punch GN 123 is also available for small series production and sheet steel with a thickness < 2 mm. |
