Low price UB300-18GM40 ultrasonic proximity switch sensor with pnp / npn output

UB300-18GM40A is a compact ultrasonic proximity switch with M18 threaded mounting, offering a detection range of 50–300mm, a blind zone of 0–50mm, and an operating voltage of 10–30VDC. It operates on the 390kHz ultrasonic time-of-flight principle for non-contact distance measurement, unaffected by object color, transparency, dust, or light, and features temperature compensation for stable measurements. It supports switch output / 0-10V analog output, and the detection window can be set via TEACH programming. Repeatability is ≤1%, with a response time of approximately 50ms. The housing is made of nickel-plated brass with IP67 protection and an M12 connector, suitable for harsh industrial environments. It is widely used for liquid level and material level measurement, transparent object detection, automation positioning, and AGV obstacle avoidance, and can be directly connected to PLC control systems.

    Working Principle

    The ultrasonic proximity switch's transmitter emits high-frequency ultrasonic waves. When these waves encounter an object, they are reflected back. The receiver captures the reflected echoes, and by measuring the time it takes for the ultrasonic waves to travel from transmission to reception, and combining this with the propagation speed of ultrasound in air, the distance between the sensor and the object can be calculated. When the distance reaches a preset threshold, the switch outputs the corresponding signal.
