Balluff BOS 12M-PS-1PD-S4-C Photoelectric Sensor

The Balluff BOS 12M-PS-1PD-S4-C is a cylindrical 12 mm diffuse photoelectric sensor (Ø12 x 70 mm) from Balluff’s 12M family, featuring a brass, nickel-plated housing and a PMMA sensing surface that withstands routine industrial use in tight spaces. It provides a PNP normally open output, operates from Ub 10 to 30 V DC, and connects via a four-pin M12x1 connector, with an infrared light source and a diffuse optical arrangement emitting a divergent beam across a 0–400 mm sensing range. The compact form factor—Ø12 by 70 mm—combined with the durable housing and PMMA sensing window supports reliable mounting in crowded panel layouts or inline installations, while the robust construction helps resist routine handling in manufacturing environments. Balluff notes CE, cULus, and EAC approvals and WEEE compliance for this model, underscoring its suitability for international automation configurations; this sensor thus pairs readily with common industrial controllers that supply 10–30 V DC and provide M12-style sensor inputs.
