Balluff BOS 18KF-PA-1FR-C-02 Cylindrical Diffuse Sensor

The Balluff BOS 18KF-PA-1FR-C-02 is an M18 cylindrical fiber‑based sensing base from Balluff’s 18KF family, designed for fiber‑optic sensing with easy integration into compact automation layouts. It provides a PNP output that can be configured as normally open or normally closed and operates from a 10–30 VDC supply. The unit measures Ø18 x 82.5 mm and uses a rugged PBT housing, with a 2.00 m PVC‑jacketed cable for flexible mounting. The sensing principle is a fiber optic device, compatible with Balluff plastic and glass fibers, enabling sensing through fiber tips in tight spaces. A red status LED indicates when the output is active, and the Sn sensitivity setting allows adjustment to suit the target and mounting conditions. This model carries the BOS00JH ordering code and complies with CE, UKCA, cULus, and WEEE requirements. The BOS 18KF family is commonly used in automation for localized sensing tasks where an M18 cylindrical form factor and fiber‑coupled heads are advantageous, such as conveyor lines, machine guarding, or robotic pickup and placement stations where ambient conditions or geometry restrict direct sensing.
