Product Positioning

The 3SE5122-0KC02 is a metal-cased mechanical position switch from the Siemens SIRIUS 3SE5 series. It uses a stainless steel round-headed plunger actuating head (including overtravel) to detect axial push-in signals and is suitable for linear positioning applications requiring buffer protection.

Core Product Advantages and Features

Stainless steel round-head plunger

The round-head plunger incorporates an overstroke design to absorb excessive travel and prevent mechanical damage.

1NO/2NC slow motion contact

The contact action is synchronized with the plunger stroke, making it suitable for precision axial positioning control.

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.
