Baumer UNDK 30P3712/S14 Ultrasonic Sensor

The Baumer UNDK 30P3712/S14 (Part No: 10232774) is an advanced ultrasonic proximity sensor engineered to deliver accurate non-contact distance measurement within a range of 60 mm to 400 mm. This sensor features a PNP break function (Normally Closed) output with a current capacity of 200 mA, making it suitable for standard control circuits. Powered by a 12–30 VDC supply, it supports a response time of less than 25 ms, ensuring reliable detection in fast-moving applications. A potentiometer is integrated into the unit for easy on-site range adjustment.

With a repeat accuracy of 0.5 mm and a hysteresis of 4% Sde, the UNDK 30P3712/S14 offers consistent performance in environments with varying target positions. It operates at a sonic frequency of 400 kHz, balancing resolution and noise immunity. Housed in a rugged rectangular body made of polyester and die-cast zinc, the sensor has dimensions of 30 mm x 65 mm x 31 mm, allowing compact installation in constrained panels or machine frameworks. The M12 connector simplifies wiring and serviceability, while the green LED indicator provides instant visual feedback during setup and operation. Designed for use in harsh environments, it meets the IP67 protection standard and performs reliably between -25°C and +60°C. Trusted by automation professionals, the Baumer UNDK 30P3712/S14 combines durability, fast response, and flexible adjustment in one compact ultrasonic sensing solution.

The UNDK 30P3712/S14 is widely used in automation systems for non-contact detection where optical sensors fall short—such as transparent, glossy, or dusty target surfaces. It excels in level sensing of bulk solids, liquids, and irregular shapes, making it ideal for packaging machines, filling stations, and storage bins. Its 400 mm detection range supports mid-distance object monitoring in automated assembly and logistics workflows.

Engineers often integrate this model into conveyor systems to detect object presence regardless of color or material. It also supports robotic positioning tasks where mechanical contact must be avoided. The potentiometer adjustment allows fine-tuning on-site, reducing the need for external programming tools. The fast response time ensures that even small or fast-moving items are reliably detected without signal lag. Because of its robust housing, IP67 rating, and compact footprint, the UNDK 30P3712/S14 is also well-suited for machine tools and industrial washdown zones. For training institutes and engineering labs, this sensor provides an ideal example of industrial-grade ultrasonic technology in action.
