SIEMENS Mechanical Safety Limit Switches Overview

Siemens offers a wide range of mechanical safety limit switches designed to monitor the position of moving parts on machines and equipment to ensure the safety of personnel and equipment. These switches

 provide reliable signals when hazardous movements or positions are detected.

Product Detailed Description

• Function:

• Monitors the position of moving parts on machines and equipment.

• Triggers switch contacts through mechanical action when moving parts reach preset safety limit positions.

• Provides normally open (NO) and/or normally closed (NC) safety contacts for safety circuits.

• Forced guided contacts ensure reliable opening of the safety circuit even in case of a fault.

• Features:

• Robust industrial housings to withstand harsh environments.

• Variety of actuators (e.g., roller lever, hinge lever, plunger, etc.) to suit different application requirements.

• Forced guided contacts compliant with safety standards (e.g., IEC 60947-5-1).

• High mechanical and electrical life.

• Various connection methods (e.g., screw terminals, cable entries).
