Introduction
GXUS series ultrasonic sensors cover a variety of application scenarios in industrial automation. Whether it comes to material handling, mobile equipment, food and beverage, fill level measurement or detection tasks at gates and doorways: they offer solutions for the most different application requirements.
Sensors with digital switching outputs or an analog 4-20 mA interface are commonplace. Most sensors can be taught-in or parameterized via an interface and therefore adapted to the respective application.

Adjusting the evaluation limits
The ultrasonic sensor features an analogue output with two teachable evaluation limits. These are set by applying the supply voltage -UB or +UB to the TEACH-IN input. The supply voltage must be applied to the TEACH-IN input for at least 1 s. LEDs indicate whether the sensor has recognized the target during the TEACH-IN procedure. The lower evaluation limit A1 is taught with -UB, A2 with +UB.
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)
Evaluation limits may only be specified within the first 5 minutes after Power on.
To modify the evaluation limits later, the user may specify the desired values only after a new Power On.
TEACH-IN rising ramp (A2 > A1)
- Position object at lower evaluation limit
- TEACH-IN lower limit A1 with - UB
- Position object at upper evaluation limit
- TEACH-IN upper limit A2 with + UB
TEACH-IN falling ramp (A1 > A2):
- Position object at lower evaluation limit
- TEACH-IN lower limit A2 with + UB
- Position object at upper evaluation limit
- TEACH-IN upper limit A1 with - UB
Default setting
A1: unusable area
A2: nominal sensing range
Mode of operation: rising ramp
