Baumer Electric GmbH UNDK 20P7914 S35A Sensor

Baumer UNDK 20P7914/S35A is a rectangular ultrasonic proximity sensor that detects objects non‑contact in industrial automation, housed in a polyester enclosure with an M8 connector. It offers a nominal sensing range of 10 to 200 mm (Sd) and a maximum sensing limit of 30 to 200 mm (Sde), with a typical hysteresis of 4% Sde, repeatability of 0.5 mm, and a 380 kHz sonic frequency. Powered from 12 to 30 V DC, it draws up to 35 mA with no load and provides a PNP normally closed output rated up to 200 mA, with residual voltage under 2 V and protection against short circuits and reverse polarity. Measuring 20 mm wide, 42 mm high, and 15 mm deep, the device is IP67 rated, operates from -10 to +60 C, and features teach‑in adjustment with a blinking indicator and a green output LED, making it suitable for conveyor, packaging, and other automation tasks requiring reliable non‑contact presence/distance sensing.
