Adjusting the evaluation limits
The ultrasonic sensor features an analogue output with two teachable evaluation limits. These are set by applying the supply
voltage -U
indicate whether the sensor has recognised the target during the TEACH-IN procedure. The lower evaluation limit A1 is taught
with -U
Two different output functions can be set:
1. Analogue value increases with rising distance to object (rising ramp)
2. Analogue value falls with rising distance to object (falling ramp)
TEACH-IN rising ramp (A2 > A1)
- Position object at lower evaluation limit
- TEACH-IN lower limit A1 with - U
- Position object at upper evaluation limit
- TEACH-IN upper limit A2 with + U
TEACH-IN falling ramp (A1 > A2):
- Position object at lower evaluation limit
- TEACH-IN lower limit A2 with + U
- Position object at upper evaluation limit
- TEACH-IN upper limit A1 with - U
Default setting

A2: nominal sensing range

Installation conditions
If the sensor is installed at places, where the environment temperature can fall below 0 °C, for the sensors fixation, one of the
mounting flanges BF 12, BF 12-F or BF 5-30 must be used. In case of direct mounting of the sensor in a through hole, it has to be
fixed at the middle of the housing thread.
