Electronic Interface and Signal Definition
Sensor Function Description
The ultrasonic sensor features a switch output with two teachable switching points. These are set by applying the supply voltage - UB or + UB to the TEACH-IN input for at least 1 second. LEDs indicate whether the sensor has recognized the target during the TEACH-IN procedure.
TEACH-IN Modes
- Window mode (normally-open/normally-closed)
- Switching point mode
- Large hysteresis interval mode
- Object detection presence mode
Installation Conditions
If installed in environments below 0℃, proper protective measures must be taken. When mounting in a through hole using steel nuts, fix at the middle of the housing thread.
