LTR-4206

The LTR-4206 series consist of a NPN silicon phototransistor mounted in a lensed, clear plastic, end looking package. The lensing effect of the package allows an acceptance half angle of 10° measured from the optical axis to the half power point. This series is mechanically and spectrally matched to the LTE-4206 series of infrared emitting diodes. The LTR-4206E is a special dark plastic package that cut the visible light and suitable for the detectors of infrared application.
