2005-02-10 1
Beschreibung
SFH 5110 ist ein Infrarot-Empfänger für die Erken-
nung von Signalen aus Infrarot-Fernbedienungs-
systemen und bestehen aus Fotodiode, Vorver-
stärker, automatischer Verstärkungsregelung,
Bandpaß-Filter und Demodulator. Das Gehäuse
ist zur Unterdrückung des Tageslichteinflusses
schwarz eingefärbt.
