FAQ

Question?
What is the typical sensing range for the HRTR 3B.66 sensor?
Answer:

The sensing range for this series is adjustable via a potentiometer on the housing. It is designed for short-range detection, typically up to 150mm on a standard white target (90% remission), depending on the target object’s color, size, and reflectivity.

Question?
Is the attached grey connector a standard sensor connector?
Answer:

No, the large grey rectangular connector is a heavy-duty industrial type, not a standard M8 or M12 sensor connector. This suggests the sensor was part of a specific machine’s wiring harness, offering a more robust connection than standard types.

Question?
How can I adjust the sensitivity of this sensor?
Answer:

The sensitivity and detection range can be adjusted using the small screw-head potentiometer located on the top surface of the red sensor housing. This allows for fine-tuning the sensor’s performance to match the specific application requirements.
