Product Positioning

The 3SE5122-0KE01 is a metal-cased mechanical position switch from the Siemens SIRIUS 3SE5 series. It uses a roller rocker arm action head to detect the position signal of mechanical parts and is suitable for end-of-travel positioning and safety interlocking circuits in various automation equipment.

Core Product Advantages and Features

Roller rocker arm action head

A metal rocker arm with 22mm plastic rollers is suitable for rotary or sliding cam-triggered detection.

1NO/2NC slow motion contact

The slow-motion contact design synchronizes the contact movement with the actuator stroke, making it suitable for low-speed precision positioning applications.

56mm wide metal casing

The durable metal casing, combined with cathode electrocoating, enhances its corrosion resistance.

IP66/IP67 protection rating

Adaptable to dusty, humid, and washing environments, suitable for harsh industrial settings.
