Balluff BES 516-326-BO-C Inductive Proximity Switch

Balluff BES 516-326-BO-C is an M18x1, cylindrical inductive proximity switch that detects metal targets with a 5 mm nominal sensing range. It operates on 10–30 V DC and provides a PNP normally-open output in a three-wire configuration, with a maximum load current of 200 mA. The rugged housing is nickel-plated brass with a PA12 sensing face and measures Ø18 x 76.5 mm, designed for flush mounting in industrial environments. It is IP68 protected against dust and immersion, and includes polarity reversal and short-circuit protection for reliable operation in harsh settings. The unit ships with a PVC-jacketed cable assembly (3 conductors) at a 2.0 m length, suitable for straightforward wiring in automation lines. Key electrical and performance data include Sn = 5 mm, Sa = 0–4 mm, a switching frequency up to about 900 Hz, and a static voltage drop near 1.5 V, making it capable of rapid position sensing on conveyors, machines, and fixtures. The BES 516-326-BO-C is designed for DC operation in industrial control schemes (DC 13 utilization) and complies with relevant standards, including a rated insulation voltage of 250 V AC and an operating temperature range of -25 to +70°C, ensuring dependable sensing across typical manufacturing environments.
