Balluff BES02KR Inductive Proximity Switch

The BALLUFF BES02KR inductive proximity switch provides non-contact metal detection for reliable position sensing in industrial automation. The device uses an electromagnetic field to detect metallic objects and is built in a nickel-plated brass housing with an M12 cylindrical form factor (variant-dependent). Its sensing distance is approximately 8 mm, suitable for compact OEM machinery. The BES02KR offers either PNP or NPN output (variant dependent) and operates on 10–30 V DC, with switching frequencies up to about 1000 Hz (variant dependent). It’s designed for harsh environments, with IP67/IP68 protection depending on variant, and connection options include an M12 connector or a cable version (variant dependent). Operating temperature range is -25°C to +70°C, enabling use across typical industrial settings. Common applications include position sensing, end-of-travel detection, part verification, and machine interlocking in conveyor systems, packaging machinery, CNC equipment, robotics, and general factory automation.
