1. Counting separated opaque cartons across a conveyor
A conveyor can pass separated opaque cartons between the sensor and a correctly aligned reflector. Each carton interrupts the returned beam, and external counting logic evaluates the PNP switching transitions. Installation uses the range limits of the actual reflector, including minimum distance, while commissioning checks carton opacity, separation and speed against the response and switching-frequency conditions.
Problem Solved
A beam-interruption reference helps external counting logic register separated cartons across a conveyor, using the actual reflector arrangement and verified pulse spacing for the selected switching mode.

2. Confirming an opaque carrier at a transfer stop
A transfer station can position the reflector so an arriving opaque carrier blocks the returned beam when seated at the stop. The potentiometer adjusts the received-light condition and the selector matches light/dark behavior to external sequencing logic. Setup checks carrier geometry, final position and reflector alignment so the blocked condition corresponds to the monitored arrival point.
Problem Solved
A seated-carrier reference helps external transfer logic coordinate the next process step using an observed position condition, with beam placement checked against the actual carrier geometry.

3. Monitoring an occupied point in an opaque-part chute
A chute can place a returned reflector beam across a defined point where accumulated opaque parts interrupt it. External monitoring logic samples the PNP state to identify occupation of that point. Installation checks reflector range, alignment, part geometry and contamination effects; the detected condition represents the monitored beam position and requires application-specific logic to interpret sustained blockage.
Problem Solved
An occupied-point reference helps external monitoring logic identify persistent blockage at a chute location, supporting a process response when accumulated parts interrupt the checked reflector beam.
