Customers have reported that the sensor fails to detect wooden strips crossing the conveyor belt. Even with the distance adjustment knob set to maximum sensitivity, the sensor indicator failed to trigger. Only 1 in 4 of the wooden strips were sensed by the infrared strip of light emitted by the photoelectric development.

After remote diagnosis, our technician found that the wooden strip was only covered by a quarter of the IR strip. To ensure a stable signal, the object must be covered by at least one third of the area of the IR strip to have a stable signal output. We realigned the sensor mounting position to extend the coverage area.
