| Infrared Devices telecontrolli IRD1 Infrared Pulse Detector General description The IRD1 is an hybrid circuit that allows to realize an infrared barrier when utilized with an infrared pulse transmitter (IRT1). IRD1 detect IR pulses and activate the output signal when the barrier is interrupted by an object. It shows stable electric characteristics thanks to the "Thick film hybrid" tecnhology.
