Q45U Ultrasonic Sensor Datasheet

This datasheet describes the Q45U series of piezoelectric proximity mode sensors with push-button programming of sensing window limits, featuring bipolar discrete outputs (NPN/PNP) and ultrasonic detection from 250 mm to 3.0 m. It covers models, specifications, temperature compensation, DIP switch settings for ON/OFF or HIGH/LOW modes, and step-by-step instructions for programming near and far sensing limits.
