Baumer Electric UNDK20P6914S35A Ultrasonic Proximity Sensor

The Baumer UNDK20P6914S35A Ultrasonic Proximity Sensor combines compact size with robust, industrial-grade sensing for short-range object detection. It uses a 380 kHz ultrasonic transceiver to detect targets from 20 to 200 mm away, with repeat accuracy of 0.5 mm and a resolution better than 0.3 mm. The rectangular polyester housing measures 20 mm wide by 42 mm high by 15 mm deep and is mounted with an M8 connector; it carries IP67 protection and operates from -10 to +60 C. Its supply range is 15–30 VDC, and it provides a voltage-output signal (0–10 V or 10–0 V) with up to 20 mA output, along with teach-in adjustment, target-indication flashing, and a yellow/red LED indicator for status. Short-circuit and reverse-polarity protection are included to help ensure reliable operation in harsh environments.
