UA18CAD22NPM1TI is an M18 cylindrical ultrasonic diffuse sensor with two digital NPN switching outputs and M12 plug connection, designed for level control and distance measurement applications. The sensor features a rated operating distance of 200–2200 mm with a blind zone of =200 mm, a beam angle of ±7°, and repeatability of 0.5%. It operates on 15–30 VDC with a no-load supply current of =50 mA, a carrier frequency of 200 kHz, and response times of =500 ms for both ON-OFF and OFF-ON transitions. The housing is constructed from PBT with an epoxy-glass resin front and provides IP67 protection against dust and water ingress, with temperature compensation active across the operating range of -20°C to +60°C. This sensor is ideal for industrial level monitoring, tank filling/emptying control, and distance measurement in harsh environments where robust, microprocessor-controlled ultrasonic detection is required.
