Balluff BES01KA 516-371-EO-C-PU-02 Inductive Proximity Sensor

The BALLUFF BES01KA 516-371-EO-C-PU-02 inductive proximity sensor is a stainless steel, Ø6.5 x 45 mm cylindrical device designed for non-contact metal detection in industrial automation. It detects metallic objects via an electromagnetic field with a flush-mount sensing distance of 1.5 mm, making it suitable for tight spaces on conveyors, packaging lines, CNC equipment, and robotics. The device provides a PNP, Normally Open output and operates from 10–30 V DC with a switching frequency up to 5000 Hz, enabling reliable, fast part detection and machine sequencing in continuous-duty environments. Its rugged housing and IP68 protection ensure resilience against dust, water immersion, and washdown; the PUR-jacket cable typically runs 2 m for flexible installation. Operating temperatures span -40°C to +85°C, covering harsh factory floors, and common replacements include Pepperl+Fuchs NJ series inductive proximity sensor (M6/M8 flush mount equivalent), IFM IE series inductive proximity sensor (similar sensing range class), and Turck BI series miniature inductive proximity switches, making it a solid choice for position sensing, machine automation control, and end-of-travel or part-detection tasks in OEM machinery and production equipment.
