1. Carton counting on a conveyor
A conveyor carries separated opaque cartons through the optical path between the sensor and an opposite reflector. Each carton blocks the returned red beam and produces a switching transition through the PNP output. The 1 ms maximum response supports pulse timing, while the E39-R1S reflector permits a working path between 100 mm and 4 m.
Problem Solved
Provides discrete carton-passage events from interruptions of the returned beam, allowing the control system to count packages without a contacting lever in their travel path.

2. Tray occupancy at an indexing station
An indexing station needs to identify whether an opaque tray is present across its loading position. The sensor and reflector form a fixed optical line that the tray interrupts when seated. Selectable Light-ON or Dark-ON operation sets the output logic, and the one-turn adjuster supports setup for the installed reflector path and target geometry.
Problem Solved
Distinguishes a loaded tray position from an empty station through beam interruption, giving the indexing sequence a noncontact occupancy condition before advancing the process.

3. Chute backup indication
A discharge chute needs to recognize when opaque packages accumulate above a selected level. A sensor faces a reflector across the chute, and accumulated packages interrupt the returning light. Its PNP switching state provides a backup indication to the feed controls, while local operation and stability indicators show the optical condition during observation.
Problem Solved
Identifies a blocked discharge line through loss of the reflector return, helping the feed sequence respond to accumulation before additional packages enter the waiting area.
