Abstract
A non-contact sensor system controls movement of a door moving in a first direction. The system includes a rigid mounting bracket attached to a leading edge of the door, a transmitter extending a distance beyond a leading edge of the door at a first door end for transmitting a signal toward a second door end. The transmitter is attached to the rigid mounting bracket by a first moveable member configured to engage a surface when the door closes and moving to a retracted position. The sensor system further includes a receiver extending a distance beyond the leading edge of the door at the second door end in alignment with the transmitter for detecting the signal and for generating an output signal. The receiver is attached to the rigid mounting bracket by a second moveable member configured to engage the surface when the door closes and moving to the retracted position.
