Special Features:

Gallum arsenide infrared emitting diode optically coupled to a monolithic silicon emitting phototransistor detector; closely matched current transfer ratios; plastic soic-8 surface mount package; b (ceo) of 70 volts; 0.05 inch lead spacing; compatible with dual wave; vapor phase and ir reflow soldering; isolation of 2500 vac (ms) ; -40 to 100 degrees c operating temperature

Properties:

A device containing one or more light sources (either incandescent, glow, or solid state, lamps) opticallycoupled to one or more semiconductor type photo-sensitive elements, all of which are contained in an opaque enclosure. Light generated within the device by the application of an appropriate electrical input to the light source(s) acts upon the light sensor(s) to produce a corresponding output or change in some electrical quantity or variation in some electrical property. For items in which the light in directed at another item and the reflected light is interpreted (read) see scanner, optical.
