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.
Applications
D Generally used for industrial processing and
controlling, end of tape detector
Features
D Miniature case with lens D Detector with optical filter, protected against
ambient light
96 12316
D Detector case black for easy identification of the
emitter and detector
D Emitter-angle of half-intensity ± ϕ = 35° D Detector-angle of half sensitivity ± ϕ = 35° D Emitter and detector in sideview case D High CTR ≥ 5%
