Typical Applications

This sensor is widely used for detecting the presence or position of metal parts in:

• Machine tooling and automation

• Conveyor systems

• Material handling equipment

• Packaging machinery

Important Note

This is an NPN (sinking) output, normally open (NO)​ sensor. In the NO configuration, the output switches to 0V (ground) when a target is detected. Ensure this output type is compatible with your PLC or controller input module. For a PNP (sourcing) or normally closed (NC) version, a different part number is required.
