The Baumer UNDK 20U6903/S35A 10158275 is an ultrasonic sensor designed for precise distance measurement within a range of 100 to 1000 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 80 ms and has a sonic frequency of 240 kHz. It includes a teach-in adjustment, target indication flashing for alignment aid, and dual-color LED indicators for operational status. The sensor is powered by a 15 to 30 VDC supply, consumes a maximum of 35 mA, and supports voltage output signals of 0 to 10 V or 10 to 0 V. It offers robust protection features including short circuit and reverse polarity protection. The compact, rectangular housing is made from polyester, measuring 20 mm in width, 42 mm in length, and 15 mm in depth, and it connects via an M8 connector. Suitable for operating temperatures from -10 to +60 °C, the sensor is IP 67 rated, ensuring protection against dust and water ingress.
