The Baumer UNAR 12U9914/S14H 11141423 is a chemically robust ultrasonic sensor designed for precise distance measurement within a scanning range of 20 to 200 mm. It features high repeat accuracy of 0.5 mm and a resolution of less than 0.3 mm. The sensor operates with a response and release time of less than 30 ms and minimal temperature drift. Operating at a sonic frequency of 380 kHz, it includes external Teach-in adjustment and lacks an LED alignment aid. Certified by Ecolab, it supports a voltage supply range of 15 to 30 VDC and has a maximum current consumption of 35 mA. The output is a variable voltage signal (0 to 10 V or 10 to 0 V) with a maximum output current of 20 mA. It offers short circuit and reverse polarity protection. The sensor's cylindrical stainless steel housing (1.4404 V4A) with a Parylene coating and EPDM O-ring is durable against pressures up to 6 bar for 20,000 cycles. Dimensions are 12 mm in diameter and 70 mm in length, with an M12 connector for easy integration. It operates effectively in temperatures ranging from 0 to +60 °C and is rated IP 67 for water and dust resistance.
