Siemens SIRIUS 3SE5122-0CE01 Roller-type rocker arm metal housing positioning switch/limit switch

Product Positioning

The 3SE5122-0CE01 is a heavy-duty metal-cased positioning switch from the Siemens SIRIUS 3SE5 series. It features a metal rocker arm and a 22mm plastic roller actuating head, making it suitable for mechanical travel end detection and interlocking control applications.

Core Product Advantages and Features

Roller rocker arm action head

The metal rocker arm, combined with 22mm plastic rollers, can withstand lateral impact forces and is suitable for triggering the stroke of rotation or translation mechanisms.

1NO+1NC quick action contact

It has one normally open and one normally closed fast-acting contact built in, which provides rapid switching response and stable and reliable action signal.

IP66/IP67 metal enclosure protection

The 56mm wide metal casing is cathodic electrocoated and has an IP66/IP67 dustproof and waterproof rating, making it suitable for harsh industrial environments.

High mechanical life

The mechanical life reaches 15 million operating cycles, and the electrical life (AC-15, 230V) reaches 100,000 cycles, reducing the replacement frequency.
