🔹 Typical Applications
Transparent material inspection on packaging lines, glass bottle detection, transparent film break monitoring, workpiece counting on conveyor lines, position confirmation in material handling & logistics systems.
🔹 Accessories & 交換オプション

Interchangeable variants within the BOS 18KF series (different cable types, NPN output or IO-Link versions).
国内代替品: M18 retroreflective photoelectric sensors with transparent detection function; verify 4.5 m range, PNP output and transparent sensing performance before replacement.
🔹 Pin Assignment (M12 4-pin Connector)

BOS00K3 (BOS 18KF-PA-1QD-S4-C) 試運転 & トラブルシューティングガイド
動作原理: Retroreflective photoelectric sensor optimized for transparent object detection. A reflector is mandatory; it does not work as a diffuse sensor.
- オンサイトでの試運転手順 (follow step by step)
- Wiring Check
M12 4-pin pinout:
1 茶色: DC+ 10~30V
3 青: DC 0V
2 黒: PNP出力
4 白: NO/NC switching
White wire floating: いいえ; white wire shorted to GND: ノースカロライナ州
Never short positive and negative terminals; supply voltage must not exceed 30 VDC.
- 取り付け & Reflector Selection
推奨 original balluff reflectors: BOS-R10, BOS-R20. Generic reflectors work but reduce stability for transparent targets.
Keep the sensor face parallel to the reflector; deflection angle < 5°.
Keep operating distance between 0.3~4 m; avoid the full 4.5 m maximum range, leave 10% safety margin for stable operation.
Transparent workpieces must pass directly through the light beam between sensor and reflector; avoid oblique beam occlusion.
- Beam Alignment
Power on and slowly adjust the sensor angle until the green LED stays steadily lit (receiving reflected light from the reflector).
Insert the transparent workpiece into the beam: green LED turns off (signal triggered). Remove the workpiece, green LED lights up again.
Center the red light spot on the reflector for best anti-interference performance.
- Environmental Notes (critical for transparent detection)
Detection stability varies with material thickness and refractive index: thick glass bottles are easier to detect than thin PET films.
Condensation, oil stains or scratches on transparent surfaces will easily cause missed detections.
Avoid direct strong sunlight or high-bay lighting shining onto the optical window.
- 一般的な障害, 原因 & ソリューション
| 故障現象 | 根本的な原因 | 救済策 |
| Green LED never lights up after power-on (no return light) | ① Power polarity reversed; ② Reflector dirty/missing; ③ Misaligned angle; ④ Supply voltage below 10 VDC; ⑤ Dirty optical lens | Check positive/negative wiring; clean or replace reflector; re-align beam; measure supply voltage; wipe the sensor window |
| LED keeps on even when transparent workpiece blocks the beam | ① The beam is not fully blocked by the transparent part; ② The film is ultra-thin with very low light attenuation; ③ The reflector is too close; ④ Ambient stray light interference | Adjust beam position to ensure full occlusion; shorten sensing distance; add anti-glare shielding; switch to polarized reflector |
| Random signal flicker / 誤ったトリガー | ① Lens or reflector contaminated with dust/oil; ② Vibration causing angle drift; ③ Shiny surrounding surfaces reflecting light back; ④ Voltage fluctuation | Regularly clean optical surfaces; lock the sensor mounting nut; install polarizing filter; stabilize the power supply |
