Advantages HLM-SS safety hinge limit switches stainless steel 316

Hinge design with stainless steel provides:

• seamless integration into standard hinges without extra mounts;

• hygiene (FDA/EHEDG, smooth surface for CIP/SIP washdown);

• high safety level (PL e / SIL 3, tamper-proof);

• extreme condition resistance (IK10 impact, vibration). Compact construction minimizes space and simplifies installation.

Applications HLM-SS safety hinge limit switches

• Food industry: Door interlocks on conveyors, packaging lines.

• Pharmaceuticals: Lid protection in sterile zones.

• Chemical industry: Equipment hinges in aggressive environments (ATEX option).

• Machine building: Machine guards and robots.

Installation and connection HLM-SS stainless steel 316

1. Insert into door/lid hinge, secure with M4 screws.

2. Connect cable (standard 2 m, M12 option) to terminals.

3. Verify actuation angle (±1°) and fixation. Maintenance — visual inspection, annual testing.
