Balluff BFS-27K-PSR-L02-S115 Photoelectric Sensor

Balluff BFS-27K-PSR-L02-S115 is a compact color-sensing photoelectric sensor from Balluff’s BFS 27K family that uses white LED illumination (400–700 nm) to identify and differentiate colored targets within a 5–45 mm sensing range. The unit is housed in ABS with a glass optical surface, measuring 50 × 50 × 25 mm and weighing about 100 g, and it uses an 8‑pin M12 connector for wiring. It operates on 10–30 V DC with a no‑load current of up to ~60 mA and provides three transistor outputs (PNP or NPN) with up to 100 mA per channel. Setup is aided by teach‑in and status indicators, including an output function indicator and channel LEDs for quick alignment and diagnostics. The device is rated IP67 for rugged protection and covers an ambient temperature range of -10 to +55 °C, making it suitable for industrial environments such as packaging lines, sorting, and material handling where color or reflectivity matters. The BFS-27K-PSR-L02-S115 variant represents a color sensor option within the BFS 27K lineup, designed to reliably detect and differentiate colored parts with repeatable results in demanding applications.
