Abstract
A non-contact sensor system controls movement of a door moving in a first direction by actuation of a device. The system includes a transmitter extending a predetermined 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 door by a first moveable member which is capable of engaging a surface when the door closes and moving to a retracted position. The sensor system further includes a receiver extending a predetermined 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 when the signal is blocked. The receiver is attached to the door by a second moveable member which is capable of engaging the surface when the door closes and moving to the retracted position.
