Balluff BOS 23K-PA-RH10-S4 Diffuse Photoelectric Sensor

Balluff BOS01FL (BOS 23K-PA-RH10-S4) is a diffuse photoelectric sensor with background suppression that detects objects against challenging backgrounds without being misled by color or surface. It operates from a 10–30 V DC supply and provides a PNP output capable of NO/NC wiring, making it compatible with common automation controllers. In diffuse mode, the sensing range is specified from approximately 3 to 800 mm, using a red-light emitter for reliable detection of small parts on conveyors or in assembly setups. The BOS01FL variant consolidates the sensing element and electronics in Balluff’s compact BOS housing, delivering consistent, color-insensitive detection in tight installations where background clutter must be ignored. This model is listed as a diffuse sensor with background suppression and is widely used for straightforward presence/absence checks and simple part-detection tasks in industrial environments.
