High precision UB800-18GM40A mini type ultrasonic proximity switch sensor

The UB800-18GM40A is a compact ultrasonic proximity switch with a detection range of 50–800mm and a blind zone of 0–50mm, compatible with 10–30VDC power supply. It uses a 255kHz ultrasonic time-of-flight principle for non-contact distance measurement, unaffected by color, dust, or mist. It supports 0–10V analog or PNP/NPN switch output, with TEACH programming and three-color LED status indication. The nickel-plated brass housing has IP67 protection and an M12 connector, with a response time of about 100ms and repeatability of ±0.5% FS. It is suitable for liquid level, material level, transparent object detection, and automation positioning, compatible with PLC 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.
