The Baumer UNAR 18P7912/S14G 10162129 is a chemically robust ultrasonic sensor designed for precise distance measurement within a scanning range of 60 to 400 mm. It features a repeat accuracy of 0.5 mm and a temperature drift of less than 0.18% Sde/K, ensuring reliable performance under varying conditions. The sensor has a quick response and release time of less than 25 ms, operates at a sonic frequency of 400 kHz, and includes a teach-in adjustment for easy setup. It is equipped with a target indication flashing for alignment aid, a green LED output indicator, and is Ecolab certified. The sensor supports a voltage supply range of 12 to 30 VDC, has a maximum current consumption of 35 mA, and includes safety features such as short circuit and reverse polarity protection. The cylindrical stainless steel housing, coated with Parylene and equipped with an FFKM O-ring, ensures durability and resistance to harsh chemicals, withstanding up to 6 bar pressure for 20,000 cycles. It offers a connection via an M12 connector, operates within a temperature range of 0 to +60 °C, and is rated IP 67 for protection against dust and water ingress.
