Product Positioning

The 3SE5112-0BD02 is a roller plunger type limit switch from the SIRIUS 3SE5 series. It uses a stainless steel roller plunger to sense linear travel and provides travel signals through slow-acting contacts.

Core Product Advantages and Features

Stainless steel roller plunger

The 13mm stainless steel roller plunger can withstand frequent mechanical impacts and maintain stable stroke sensing.

1NO-1NC slow motion contact

It adopts a slow-moving (creeping) contact design and has a positive disconnect mechanism, making it suitable for specific control logic.

High-protection metal casing

The 40mm metal casing is coated with cathodic electroplating, achieving an IP66/IP67 protection rating.

Low motion design

With a minimum actuation force of approximately 20N, it is suitable for pairing with lightweight triggering structures and precision positioning devices.
