Function: UBR250-F77-E2-V31

The ultrasonic sensor works like a retroreflective sensor. It transmits ultrasonic packages in quick succession and responds to their reflection off a reference object at a defined distance.

The distance T to the reference object can be taught in. The sensor has a switching output. The output switches when the sensor either no longer receives the echo from its reflector or no longer receives it as the first echo.
