Balluff BOS 18M-PS-1XB-E5-C-S4 Photoelectric Sensor

Balluff BOS 18M-PS-1XB-E5-C-S4 is a cylindrical M18 diffuse photoelectric sensor that detects objects by reflecting infrared light off the target, using an 880 nm beam with a sensing distance up to 200 mm. It employs a PNP normally‑open output rated for up to 200 mA, powered from 10 to 30 V DC, with a typical no‑load current below 20 mA and a voltage drop under 2.5 V; it also features short‑circuit and polarity reversal protection for rugged industrial use. The device’s housing is nickel‑plated brass with a PMMA sensing face, rated to IP67, and it connects via an M12 4‑pin S4 connector, with an approximate body length of 70 mm and a weight around 40 g. On the electrical side, it offers a fast response—on‑delay and off‑delay under 5 ms—and tolerates ambient light up to about 5,000 lux while operating in temperatures from –5 °C to 55 °C; a yellow power/actuation LED provides status indication. The diffuse sensing arrangement is suitable for detecting flat or lightly textured parts, labels, or small components on conveyors or in packaging lines where a compact, metal‑bodied sensor is advantageous. This Balluff model is part of the 18M series and is designed for reliable, straightforward object detection in rugged environments, combining robust mechanical housing with straightforward electrical wiring and clear optical sensing performance.
