Balluff BOS 26K-PA-1HC-S4-C Diffuse Sensor

The Balluff BOS0089 (BOS 26K-PA-1HC-S4-C) is a compact cube‑shaped diffuse photoelectric sensor that reliably detects objects within a 30 to 300 mm sensing range. It uses diffuse triangulation with background suppression and emits a red LED beam (660 nm) with a 8 mm spot size at 200 mm, enabling consistent detection across varied surfaces and colors. Measuring 17 x 50 x 50 mm, the sensor features an ABS housing and a PMMA sensing surface, with a 4-pin M12 connector for easy wiring. It provides configurable PNP outputs (NO or NC) powered from Ub = 10–30 V DC, suitable for common industrial PLC inputs. Balluff lists approvals including cULus, CE, and UKCA, reflecting compliance with major global standards. This BOS 26K device is part of Balluff’s diffuse sensor family designed to detect parts or features on conveyors and in automation cells even against reflective backgrounds, offering background suppression to minimize false triggers. Common applications include part-detection on assembly lines, presence sensing in packaging workflows, and machine-vision‑adjacent tasks where a small, robust sensing solution is required.
