CNY65Exi
Vishay Telefunken
Optocoupler with Phototransistor Output
Description
The CNY65Exi consists of a phototransistor optically coupled to a gallium arsenide infrared-emitting diode in a 4-lead plastic package. The single components are mounted in opposite oneanother, providing a distance between input and output for highest safety requirements of > 3 mm.
Applications
