Balluff BES 516-209-BO-E Proximity Sensor Switch

Balluff BES 516-209-BO-E is a compact inductive proximity sensor switch housed in a 12 mm diameter M12 package designed for non-flush installation. The sensor measures Ø12 x 60 mm with a stainless steel housing and PA 12 sensing face, delivering a 4 mm sensing range for metal targets. It is wired with a 5 m connection and provides a normally open output, with a supply window of 20 to 250 V DC or AC. The non-polarized NO output supports both DC and AC control circuits. The device operates from −25 to 70 °C and carries an IP67 rating for dust and water resistance. A switching frequency up to 600 Hz enables reliable detection in fast-moving production environments. This model is part of Balluff’s BES 516 family and is suitable for applications such as conveyor line sensing and machine-automation tasks where a compact, rugged metal-detection switch is needed. The 516-209-BO-E variant emphasizes robust construction with a PA12 sensing surface and stainless steel housing, ensuring durability in industrial settings while offering straightforward integration with standard control systems across a wide input voltage range.
