Stainless steel latches GN 1150 are intended for use in hygienic areas and meet hygiene requirements on the operating side (front hygiene) and on the operating and latch arm side (full hygiene) due to the special mounting nuts as well as the optimized latch arm and hexagon head screw. The locking mechanism is protected by two seals (front hygiene) and multiple seals (full hygiene). 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 (front hygiene) and 22 to 44 mm (full hygiene).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. Stainless steel latches GN 1150 (front hygiene) are supplied with loosely enclosed latch arm.
