1. Checking a workpiece in a fixture
An assembly fixture can position the sensor toward the expected face of an opaque workpiece, with clear optical separation from surfaces behind the detection point. Energetic sensing evaluates reflected target light, and the potentiometer sets reception for the installed geometry. The PNP output supplies the local presence state to the sequence controller.
Problem Solved
A contactless workpiece signal identifies an occupied fixture for the controller, supporting assembly sequencing without a mechanical feeler pressing against the part at the sensing position.

2. Counting separated components on a conveyor
A conveyor can aim the sensor at a position crossed by separated opaque parts so each target presents reflected light to the receiver. The 40 mm at 800 mm optical spot defines the monitored region, while the potentiometer adapts reception to the target and background geometry. The 250 Hz switching frequency supports repeated transitions within the documented timing limits.
Problem Solved
Discrete reflected-light transitions mark individual part passages without contact, giving the controller a count input when the installed geometry separates each target from the empty path.

3. Checking opaque strip continuity
A feeder can direct the sensor toward an opaque strip at a fixed monitoring position so reflected light indicates material present. A break or runout removes the target from that optical position and changes the PNP signal. IP67 protection supports exposed machine mounting, while the 2 m cable connects to local control wiring.
Problem Solved
A change in local material presence provides an electrical indication of interrupted strip feed, helping the controller coordinate a response before additional product enters the affected process section.
