Moonroof Clear Glass Detection

As an unfinished automobile moves along an assembly line, it is essential not to overlook the process and missing parts.

This application requires a solution that reliably detects the presence of clear glass to ensure that the moonroof has been installed.

The detection of clear glass is a common challenge in the automobile industry. The optical beam of traditional photoelectric sensors will burn through clear material, making sensing results unreliable. The solution must be capable of detecting the clear glass of the moonroof.


  • Reliable detection of clear glass.
  • Remote TEACH function for easy installation setup.
  • Superb EMI/RFI noise immunity and easy visual status monitoring.

  • Moonroof Clear Glass Detection with Banner's U-GAGE T30UX Ultrasonic Sensor

Banner Engineering's U-GAGE T30UX Series Ultrasonic Sensor uses pulses of ultrasonic energy, which reflect off the target and back to the sensor, to reliably detect clear materials. The extended range and remote line TEACH functionality of the T30UX makes it possible to mount the sensor above the assembly line, looking down at passing automobiles.

In this application, the sensing limits could be quickly and easily taught using the Auto-Window feature, in which the operator teaches the same limit twice (in this case, teaching the limit with the moonroof present), automatically centering a window on the taught position. 

Among other features, Banner's T30UX offers superb EMI/RFI noise immunity and easy visual status monitoring with highly visible indicator lights. It is rated IP67/NEMA 6P.
