Additional Details:

The CNY64(B)-V consists of an infrared emitting diode (IRED) and a phototransistor in a single package. When current flows through the IRED, it emits infrared light, which activates the phototransistor, allowing current to flow in the output circuit. The isolation voltage is typically several kilovolts, providing a high level of safety. The CTR is a measure of the efficiency of the optocoupler and can vary depending on the operating conditions. Its packaging is typically DIP (Dual In-Line Package) or SMD (Surface Mount Device) and is chosen depending on the application requirements. Forward voltage is typically 1.25V. Collector-emitter voltage is around 70V.
