Product Positioning

The 3SE5122-0KD02 is a metal-cased mechanical position switch from the Siemens SIRIUS 3SE5 series. It uses a roller plunger actuating head (stainless steel roller) to detect axial push-in stroke and is suitable for position confirmation and safety interlocking of linear motion mechanisms.

Core Product Advantages and Features

Roller plunger moving head

The 13mm stainless steel roller plunger design can withstand axial linear pressing triggering.

1NO/2NC slow motion contact

The contact action is synchronized with the plunger stroke, making it suitable for linear motion control requiring precise positioning.

56mm wide metal casing

The metal casing structure combined with cathode electrocoating makes it durable and corrosion resistant.

IP66/IP67 protection rating

Industrial site requirements that adapt to dusty, humid, and washing environments.
