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.
