GXUS2000 series IP67 Distance Measuring Analogue Ultrasonic Sensor
Introduction
The Ultrasonic sensor uses sound waves to do non-contact and wear-free detection on target subjects. It can be used to detect either transparent or colored objects, metal objects or non-metallic objects, as well as solid, liquid or powdered substance. Ambient conditions such as environmental smoke, dust, environment or rain have very small affect on the detection performance of ultrasonic sensors.
Features
☆ Measuring window adjustable
☆ Program input
☆ Small unusable area

Description of Sensor Functions
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 m st 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:
- Analogue value increases with rising distance to object (rising ramp)
- 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
LED Displays
| Displays in dependence on operating mode | Red LED | Yellow LED |
| TEACH-IN evaluation limit Object det cted No object etected Object uncertain (TEACH-IN invalid) | off flashes on | | flashes | | |
| off off | |
| Normal mode (evaluation range) | off | on |
| Fault | on | previous state |
5. Installation conditions
If the sensor is installed at the environment with temperature below 0℃, it should be protected. When mounting the sensor in
a through hole by screw nuts, the sensor need to be fixed at the middle of the mounting thread.
