2001-12-10 1
Beschreibung
SFH 5110 und SFH 5111 sind Infrarot-Empfänger
für die Erkennung von Signalen aus Infraro t-Fern-
bedienungssystemen und bestehen aus Foto-
diode, Vorverstärker, automatischer Verstär-
kungsregelung, Bandpaß-Filter und Demodulator.
Das Gehäuse ist zur Unterdrückung des Tages-
lichteinflusses schwarz eingefärb t.
