· Detection of paper or cloth seam
  (using indirect grounding).

· Detection of paper or cloth edge 
  (using indirect grounding).

· Thickness control of rolling plates.

· Displacement detection and control.

· Drill positioning. 
· Material positioning.

· Detection of workpiece edges.

· Detection of press completion position. 
· Detection of mistakes in workpiece
  setting or removal. 
· Detection of minute workpieces.

Object Actuates Switch and Turns 
Built-in Monitor Indicator ON

Instantaneous operation upon contact with extremely 

limited hysteresis for high-precision position detection.

Detects minute displacement or lightweight objects with 

minimal operating force.

Built-in LED indicator ensures easy operation monitoring.

DC models provide versatile functions in combination 

with the S3D2 Sensor Controller.
