What is the Lanbao PR30-BC Series Diffuse Reflection Photoelectric Sensors? The Lanbao PR30-BC Series Diffuse Reflection Photoelectric Sensors family is Lanbao's official cylindrical diffuse-reflection photoelectric sensor platform for opaque object detection in automation cells, logistics, packaging lines, and robotics integration. The family combines 50cm adjustable and 100cm adjustable sensing options, industrial DC output choices, and cable or M12 connector installation options so engineers can select the right part number for range, wiring, and controller logic. If you are building around Arduino development boards, pairing with ESPRESSIF wireless MCU platforms, or integrating with robotics hardware from Elephant Robotics, this Lanbao family gives engineers an official, structured path to choose the right sensor variant. Features M30 cylindrical body format makes the family easy to deploy in packaging, logistics, and general automation stations where cylindrical bodies and standard brackets are preferred. Diffuse-reflection sensing is practical when you need object presence detection without a separate reflector. Multiple sensing distance choices let you balance tighter mechanical installations against longer stand-off range. NPN and PNP logic options reduce integration friction with PLCs, industrial I/O, and embedded interface modules. Cable and M12 connector versions support either simpler fixed wiring or faster field replacement and modular harnessing.
