Product Details

Baumer UNDK 30P3712/S14 is a high-performance ultrasonic proximity sensor and reliable distance detection transducer manufactured by Baumer, a renowned Swiss sensor brand. This baumer ultrasonic sensor uses ultrasonic echo principle for non-contact object detection and distance measurement, capable of detecting solid, liquid and granular targets regardless of color or surface reflectivity. It is equipped with an integrated potentiometer for easy sensing range adjustment and adopts PNP normally closed output, directly sending switching signals to PLC or industrial controllers. Fitted with a standard M12 circular connector for fast plug-and-play wiring, the compact rectangular housing supports flexible mounting on machinery frames and conveyor brackets. With IP67 ingress protection and reinforced shock resistance, this ultrasonic proximity sensor can run stably in dusty, humid and vibration-prone workshop environments. As a popular industrial spare part, this distance detection transducer serves as a drop-in replacement to restore reliable object presence and distance monitoring for automated production lines.

Supported Functions

This ultrasonic proximity sensor transmits ultrasonic pulses and receives reflected echoes to calculate target distance and confirm object presence. The distance detection transducer provides stable switching output once the target enters the preset detection zone. This baumer ultrasonic sensor suppresses false triggers caused by background clutter and minor air turbulence, and supports continuous signal feedback to the host control system. It can detect transparent objects, plastic containers and bulk materials that photoelectric sensors struggle with. If the target is out of range or signal is lost, it changes output state to notify the PLC for alarm or process interlock. It works seamlessly with Modicon and other brand PLC, conveyor control systems and packaging machinery controllers.

Core Functions

As a non-contact ultrasonic transducer, this ultrasonic proximity sensor delivers reliable presence and distance detection without touching the measured object. Its adjustable sensing window and robust PNP output make it versatile for different process requirements, while the IP67 sealed housing reduces downtime in harsh factory conditions. This distance detection transducer works as a direct spare to rebuild object detection function for legacy automated equipment.
