Abstract

Releul fotoelectric prin transparenta în spectrul infrarosu este destinat sa sesizeze trecerea unui corp opac printr-un fascicul de radiatii infrarosii, stabilit între emitator si receptor. Este constituit dintr-un emitator ce contine o dioda electroluminiscenta în infrarosu alimenteaza în impulsuri si un receptor ce contine un fototranzistor, care primeste impulsurile de la dioda electroluminiscenta în infrarosu si prin intermediul unui amplificator activeaza o dioda electroluminiscenta de indicare a focalizarii si descarca un condensator astfel încît prezenta impulsurilor tensiunea la bornele lui nu depasesc pragul fixat printr-o dioda zenner, releul electromagnetic de iesire nefiind anclansat. în situatia întreruperii fascicului de radiatii infrarosii, fototranzistorul se blocheaza, condensatorul se încarca la o tensiune superioara pragul fixat prin dioda Zennen, releul electromagnetic de iesire anclanseaza.The photoelectric relay by infrared spectrum is intended to sense the passage of an opaque body through an infrared beam established between the transmitter and the receiver. It consists of an emitter containing an infrared electroluminescent infrared diode energizing in pulses and a receiver containing a phototransistor that receives the impulses from the infrared electroluminescent diode and by means of an amplifier activates an electroluminescent diode focusing diode and discharges a capacitor so that the presence of impulses the voltage at its terminals does not exceed the threshold fixed by a zenner diode, the electromagnetic output relay being not clutched. In the case of the infrared beam interruption, the phototransistor is blocked, the capacitor is charged at a higher voltage the threshold fixed by the Zennen diode, the electromagnetic output relay clangs.
