Lanbao PSS-BC10-E2 - M18 Diffuse Reflection Sensor with M12 Connector The Lanbao PSS-BC10-E2 M18 Diffuse Reflection Sensor with M12 Connector is an M18 cylindrical photoelectric sensor for industrial automation applications where short-range object presence detection is needed together with detachable M12 wiring for faster machine service. The PSS-BC10-E2 series uses diffuse reflection sensing, 10 cm rated distance, Infrared light, 940 nm, NPN NO/NC or PNP NO/NC switching, and a 10-30 VDC supply, giving machine builders a compact sensor format for part presence, packaging, handling, and inspection stations. This listing focuses on detachable M12 4-pin connector wiring, max. 0.5 ms response time, max. 20 mA consumption current, max. 200 mA load current, reverse-polarity protection, short-circuit protection, overload protection, IP67 protection, and CE certification. For neighboring options in the same Lanbao PSS family, compare Lanbao PSS-BC10 cable version, Lanbao PSS-BC40-E2 infrared sensor, and Lanbao PSS-PM-E2 polarized sensor before choosing a sensing mode or wiring style. The sensor output can be connected to PLC digital inputs, relay interfaces, Arduino test fixtures, or ESP32 data-collection nodes when the input circuit is wired for the correct NPN or PNP output type. During commissioning, set the single-turn potentiometer, confirm the green stability indicator and yellow output indicator, and validate detection on the real target material rather than only on a bench sample.

M18 threaded body - Mounts through brackets or panels with M18 nuts; avoid over-tightening the housing. Power indicator - Green LED indicates power and stable operating state during setup. Output indicator - Yellow LED indicates switching output, short-circuit, or overload reference state. Sensitivity adjuster - Single-turn potentiometer used to tune distance or switching margin on the real target. M12 connector - Quick-disconnect interface for field wiring; select a matching cable and pinout for NPN or PNP output. Brown lead - Connect to +10-30 VDC supply in typical industrial wiring. Blue lead - Connect to 0 VDC common and share reference with the input module. Black lead - Main switching output to PLC, relay interface, or protected digital input. White lead - NO/NC mode reference; Lanbao documentation specifies positive or floating for NO mode and negative for NC mode. Installation note - Use the same sensor-to-target geometry during commissioning and production to keep repeatability stable. Packing List 1 x Lanbao PSS-BC10-E2 photoelectric sensor 1 x M18 mounting nut set and instruction manual reference, depending on current store bundle FAQ Q: What is this Lanbao PSS-BC10-E2 sensor used for?A: It is used for industrial object detection in conveyors, packaging machines, fixtures, handling systems, and automated inspection stations. Q: What is the main difference between this model and other PSS sensors?A: The key difference is the sensing mode, rated distance, and wiring style. This model uses diffuse reflection, 10 cm rated distance, and M12 4-pin connector. Q: Can it connect to a PLC?A: Yes. Use a PLC digital input module that matches the selected NPN or PNP output and the 10-30 VDC supply system. Q: Can I test it with Arduino or ESP32?A: Yes for bench testing, but use proper level shifting, isolation, pull-up or pull-down wiring, and common ground rules before connecting industrial signals to a development board. Q: Is this sensor waterproof?A: The sensor is rated IP67, but the whole installation still depends on cable sealing, connector tightening, enclosure design, and splash direction. Q: How do I choose NO or NC mode?A: Lanbao documentation uses the white wire as the NO/NC mode reference. Follow the exact wiring diagram for the variant being installed. Q: Why does the sensor switch unreliably?A: Check supply voltage, target reflectivity, alignment, sensing distance, ambient light, cable wiring, and potentiometer setting. Q: Should I choose cable or M12 connector?A: Choose the M12 connector version when fast replacement and modular wiring are important.
