Balluff BES516-300-S262-S4-D Inductive Sensor

Balluff BES516-300-S262-S4-D is a pressure-rated, cylindrical inductive proximity sensor designed for metal-detection tasks in demanding industrial environments. The device uses a 4-pin M12x1 threaded housing (Ø12 x 50 mm) and offers a short-range sensing distance of 1.5 mm, ideal for compact installations where precise metal detection is required. It operates from a 10–30 V DC supply and draws up to 200 mA, delivering a PNP normally open (NO) switching output that can interface with common PLC inputs. When mounted flush in tight machine or conveyor configurations, the sensor provides reliable, repeatable detection without physical contact, reducing wear and offering long-term durability in high-precision applications. As part of Balluff’s BES 516 family, the BES516-300-S262-S4-D is suited for end-of-travel sensing, component positioning, and metal-detection tasks on automation lines, packaging equipment, and tooling where space is at a premium and environmental demands call for robust proximity sensing.
