1. Counting transparent bottles at a guide
A guide can present separated transparent bottles across the sensor-to-reflector path. The 270° potentiometer sets sensitivity using representative bottles that produce more than 20% beam attenuation. External counting logic reads the selected PNP switching state, with setup checking bottle shape, labels, orientation, reflector spacing and transit timing against the optical range, response and switching-frequency limits.
Problem Solved
A bottle-passage reference helps external counting logic register separated transparent containers after their attenuation and presentation have been qualified for this adjustable retro-reflective sensor.

2. Checking a transparent tray at a transfer stop
A transfer stop can present a transparent tray at a repeatable position across the reflected beam. Sensitivity is adjusted for the actual tray and the installed reflector distance, verifying more than 20% attenuation in the sensing path. External sequencing logic samples the PNP state after the tray settles, with commissioning checking seams, molded features and position tolerance.
Problem Solved
A qualified tray-present reference helps external sequencing logic coordinate a transfer step, using sensitivity adjustment and a repeatable optical presentation checked against the required attenuation.

3. Monitoring transparent web presence at a feed point
A material feed can route a transparent web through a stable sensor-to-reflector path. Commissioning uses the actual web to verify attenuation above 20% and adjusts sensitivity while checking representative thickness, finish, wrinkles and angle. External process logic evaluates the selected PNP signal for material presence, with the reflector chosen and positioned within its documented sensing range.
Problem Solved
A qualified web-present signal helps external process logic recognize loss of transparent material at the checked feed point, using an attenuation level established with the actual web.
