The Baumer UNDK 20N7914/S35A 10150076 is an 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% and repeat accuracy of 0.5 mm. The sensor operates with a temperature drift of less than 0.18% per Kelvin and has quick response and release times of less than 10 ms. It emits at a sonic frequency of 380 kHz and includes a teach-in adjustment for easy setup. The sensor is equipped with a target indication flashing for alignment aid, a green LED output indicator, and operates on a 12 to 30 VDC supply with a maximum current consumption of 35 mA. It supports an NPN break function (NC) output circuit with a maximum output current of 200 mA and includes short circuit and reverse polarity protection. The rectangular housing is made of polyester, measuring 20 mm in width, 42 mm in height, 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.
