Baumer Electric UNDK 20P6914 S35A Inductive Proximity Sensor

Baumer Electric UNDK 20P6914/S35A is a compact ultrasonic proximity sensor with a PNP normally open output that detects objects at a distance from 10 to 200 mm without contact. It is powered from 12–30 V DC and uses an M8 connector for a robust, space‑saving industrial interface, making it well suited for tight spaces on automation lines. The sensor is built in a polyester housing and carries an IP67 rating for reliable operation in dusty or wet environments, with an operating temperature range from -10 to +60 °C. Setup is streamlined via Teach‑In to teach the target, and the output current is rated up to 200 mA, allowing direct interfacing with PLC inputs or small actuators. Typical applications include non‑contact presence and distance sensing on conveyors, part detection in packaging and material handling, and integration into robotic pick‑and‑place or automation cells where precise short‑range sensing is required. The UNDK 20P6914/S35A represents Baumer’s ultrasonic sensing family designed for rugged factory environments, combining a slim form factor, simple wiring, and reliable digital output for straightforward integration into control systems.
