Baumer URDK 20N6914/S35A Ultrasonic Sensor

The Baumer URDK 20N6914/S35A (Part No: 10160230) is a compact rectangular ultrasonic sensor that offers non-contact object detection across a sensing range of 0 to 200 mm. Equipped with an NPN make function (Normally Open) output, it supports up to 200 mA output current, allowing direct integration with most control circuits and PLCs. The device operates on a 12–30 VDC power supply and responds rapidly with a response time of less than 10 ms, ensuring reliable detection in fast-paced automation environments.

This model offers a repeat accuracy of 1.5 mm and operates at a sonic frequency of 380 kHz to ensure stable performance even in acoustically noisy conditions. The sensor features a Teach-in function for easy configuration without external programming tools, and a green LED indicator provides instant feedback during alignment and operation. Built with a durable polyester rectangular housing measuring just 20 mm x 42 mm x 15 mm, the URDK 20N6914/S35A is optimized for tight machine layouts. The M8 connector enables quick and secure wiring, while the IP67 protection rating ensures operation in wet, dusty, or industrial conditions. Capable of withstanding temperatures from -10°C to +60°C, this sensor is trusted by automation engineers for detecting small, transparent, or non-reflective targets where optical sensors often fail. Backed by Baumer’s precision engineering, this model is a smart and reliable choice for demanding sensing environments.

The URDK 20N6914/S35A is widely used in industrial automation setups where non-contact detection of challenging surfaces—such as transparent films, shiny metals, or liquids—is required. It is commonly integrated into bottle filling lines, container detection systems, and level monitoring units where optical sensors might misread or fail due to reflectivity or environmental conditions.

Engineers prefer this sensor for its Teach-in adjustability, allowing fast on-site calibration without external software. The short-range and compact design make it ideal for use in compact machinery, small part inspection, and robotic grippers that require precise detection within confined spaces. Maintenance teams benefit from the LED status indicator for real-time feedback during servicing. Educational institutions also use this model to teach principles of ultrasonic sensing, sensor calibration, and edge detection. For precision sensing in limited space, the Baumer URDK 20N6914/S35A proves to be a reliable and versatile performer.
