Matchable Pairs – Emitter and Detector
Description
Pairs of infrared-emitting diode and phototransistor,
matched in their optical and electrical features. These
pairs enable a lot of applications. They can be used
both for transmissive or reflective sensor functions.
The peak wavelength of the emitter is l = 950 nm.
