The Baumer URAR 18N6912/S14G 11050151 is a chemically robust ultrasonic sensor designed for precise distance measurement within a range of 0 to 400 mm. It features a reflector position range of 120 to 400 mm and boasts a repeat accuracy of 1.5 mm. The sensor operates with a sonic frequency of 400 kHz and has a quick response and release time of less than 25 ms. It includes a teach-in adjustment, target indication flashing for alignment aid, and a green LED output indicator. Certified by Ecolab, it is equipped with a voltage supply range of 12 to 30 VDC and a maximum current consumption of 35 mA. The output circuit is an NPN make function with an output current of 200 mA. It offers short circuit and reverse polarity protection, and operates efficiently with less than 2 VDC voltage drop and less than 10% residual ripple. The cylindrical stainless steel housing measures 18 mm in diameter and 91.5 mm in length, with a connector M12 connection type and a Parylene-coated active face. The sensor can withstand pressures up to 6 bar and is durable for over 20,000 cycles. Suitable for operating temperatures from 0 to +60 °C, it is IP 67 rated, ensuring protection against dust and water ingress.
