The Balluff BOS 26K-PA-1QE-S4-C is a cubic retroreflective photoelectric sensor from the 26K BOS family, measuring 17 x 50 x 50 mm. It operates on 10–30 V DC and provides PNP normally open (NO) or normally closed (NC) outputs via a 4-pin M12 connector. This red‑light sensor uses coaxial optics for a detection range of 0–5.5 m, with an ABS housing and a PMMA sensing surface. It carries CE, UKCA, cULus, and WEEE approvals; safety note: not suited for safety‑related applications.
