While conventional sensors have trouble detecting the presence of threads, the LV-NH32 can easily detect the difference between a tapped and untapped hole. With an unthreaded hole, the sensor's light is trapped and is not returned, but with a threaded hole, much of the light is reflected back to the sensor.
The LV-NH32 has an adjustable beam spot diameter, it can be changed according to the size of the hole and threads, producing extremely stable detection.
