Balluff BES M18D1-PSC 12B-SO4G Proximity Sensor

Balluff BES M18D1-PSC 12B-SO4G proximity sensor is a compact inductive sensor in an M18 threaded housing (Ø18 x 63.5 mm) designed to detect metal targets at up to 12 mm. It provides a PNP normally open output from a 10–30 V DC supply and uses a 4-pin M12x1 connector for straightforward wiring. The sensor features a brass, chrome-plated housing, a PBT sensing face, and a quasi-flush installation option for tight spaces. With an IP67 enclosure and an operating temperature range of -25 to +70 °C, it withstands dust, water ingress, and washdowns in demanding industrial environments. This model is part of Balluff’s BES line of inductive sensors, ideal for end-of-travel sensing, position detection, and proximity sensing on conveyors, tooling, and machine frames where compact metal sensing is required. The 12 mm sensing distance offers reliable switching with a compact footprint, and the M12 4-pin connection integrates with standard control circuitry. Built around Balluff’s reputation for robust industrial sensors, the BES M18D1-PSC 12B-SO4G is a durable choice for space-constrained metal-detection tasks in automated systems.
