3SE5122-0LA00-1CA0 SIEMENS Central control module

SIEMENS 3SE5122-0LA00-1CA0 Overview

The SIEMENS 3SE5122-0LA00-1CA0 is a mechanical safety limit switch belonging to the SIEMENS SENTRON PAC series. It is used to monitor the position of safety doors or movable parts on machines and 

equipment to ensure the safety of operating personnel. When a safety door is opened or a part moves to a hazardous position, the switch triggers the safety circuit, stopping the machine operation.

Product Detailed Description

• Function:

• Monitors the position of safety doors, covers, or other movable safety guards.

• Interrupts the safety circuit when a safety guard is opened or moved to an unsafe position.

• Provides positively driven contacts for reliable disconnection of the circuit even in case of contact welding.

• Features:

• Metal enclosure, robust and durable for industrial environments.

• Equipped with a roller lever actuator.

• Available with multiple contact configurations, typically including normally closed (NC) safety contacts and normally open (NO) auxiliary contacts.

• High degree of protection, typically IP66/IP67.

• Various connection methods, typically screw terminals.
