The Baumer UNAR 12P1914/S14H 11182659 is a chemically robust ultrasonic sensor designed for precise distance measurement within a scanning range of 10 to 200 mm. It features a far limit scanning range of 30 to 200 mm with a typical hysteresis of 4% Sde and repeat accuracy of 0.5 mm. The sensor operates with a temperature drift of less than 0.18% Sde/K and has quick response and release times of less than 10 ms. Operating at a sonic frequency of 380 kHz, it can be externally taught and does not include an LED alignment aid. Certified by Ecolab, it is suitable for demanding environments, supporting a voltage supply range of 12 to 30 VDC and a maximum output current of 200 mA. The sensor is equipped with short circuit and reverse polarity protection, housed in a stainless steel 1.4404 cylindrical body with a Parylene-coated active face and an EPDM O-ring. It can withstand front pressure up to 6 bar for 20,000 cycles, measures 12 mm in width and 70 mm in length, and connects via an M12 connector. Operating temperatures range from 0 to +60 °C, and it is rated IP 67 for water and dust resistance.
