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. Stainless steel latches GN 1150 are suppliedwith loosely enclosed latch arm. see also... • Technical and Assembly Instructions Page 26 • Latches GN 1150 (Stainless Steel, Full Hygiene, Hygienic Design ) Page 25 Information • Lock housing Stainless steel AISI 316L • Latch arm Stainless steel - AISI 304 for d 1 = 22 - AISI 316 L for d 1 = 30 • Sealing ring / O-ring EPDM E - Blue, FDA compliant - Temperature resistant -40 °C to +120 °C - Hardness 85 ±5 Shore A (Sealing ring) - Hardness 70 ±5 Shore A (O-ring) • Other parts stainless steel AISI 316L • All moving parts lubricated with FDA compliant special grease • Protection class IP 66 • IP Protection Classes Main Catalogue Page 2153 • Elastomer Characteristics Page 38 • Stainless Steel Characteristics Page 39 • RoHS Specification 5 2 Type SW With two spanner flats 4 Coding FH Operating side in Hygienic Design (front hygiene) • Sealing Rings GN 7600 Page 36 • Socket Keys GN 1151 Page 27 Accessory
