Emergency Safety Limit Switches

Emergency safety limit switches (HLM series, cast aluminum IP67) — robust mechanical safety devices for detecting positions of moving equipment parts like protective doors, conveyors, machine beds, and elevators. Made of cast aluminum with high IP67 dust/water protection, they offer reliable actuation with various actuator types. Compliant with EN ISO 14119, IEC 60947-5-1, PL d / SIL 2 safety level. Ideal for machine building, logistics and industrial automation with moderate hygiene needs.

Advantages HLM emergency safety limit switches IP67

Cast aluminum with various actuators provides:

• high strength and longevity in industrial conditions;

• customization flexibility (adjustable levers for different uses);

• moisture/dust protection (IP67, for wet areas);

• fast actuation with slow/instant contact options for safety. Mechanical design ensures reliability in cyclic operations without wear.

Applications HLM emergency safety limit switches

• Machine building: Position control on machines, presses, robots.

• Logistics: Protective doors on conveyors and elevators.

• Food industry: Positioning on packaging lines.

• Chemical industry: Mechanisms in aggressive environments.

Installation and connection HLM emergency safety limit switches

1. Secure housing with M4/M5 screws on moving/fixed part.

2. Adjust actuator (lever/roller) for end-position actuation.

3. Connect cable (standard 2 m, M12 option). Maintenance — annual contact and actuator inspection.
