QT50ULB Series Ultrasonic Sensor Datasheet

This datasheet describes the QT50ULB series of long-range ultrasonic sensors with TEACH-mode programming, featuring scalable analog output (0-10 V dc or 4-20 mA) and an 8-pin DIP switch bank for configuration. It covers principles of operation, temperature compensation, output slope settings, and detailed DIP switch functions for response speed, loss of echo behavior, and remote teach/enable control.
