Balluff BES M18EI-PSC72B-S04G-S Inductive Sensor

Balluff's BES M18EI-PSC72B-S04G-S is a compact inductive proximity sensor designed for rugged industrial environments, housed in an M18 body with a metal front and a flush-front profile that allows tight mounting against metal surfaces along conveyors and machinery. Marketed as BES02NJ, this pressure-rated inductive sensor provides a PNP normally open output on a 10–30 VDC supply, with an M12 connector for straightforward integration into PLCs and control networks, and it lists a 7 mm sensing distance. The part number BES M18EI-PSC72B-S04G-S corresponds to the BES02NJ model, confirming its metal-front construction, 7 mm sensing range, and standard 10–30 VDC operation, making it a reliable non-contact metal-detection solution in automated lines, packaging equipment, and machine-building contexts.
