Optoisolators are electronic devices designed to provide electrical isolation between two circuits, while still allowing for signal transfer. This isolation is achieved via an opto-coupler, which consists of a transmitter and a receiver. The transmitter is usually an LED, while the receiver may be either an efficient photodiode or a phototransistor.

The CNW85 is an optoisolator, which utilizes a phototransistor as the receiver. It is used mainly for maintaining isolation between high-power and low-power circuits, while still allowing for signal transfer between the two. The CNW85 is relatively small in size, making it suitable for use in compact electronic systems.

Applications

The CNW85 has several applications, including isolating signals from a noisy environment by providing electrical isolation between the noise and the equipment being protected. It can also be used in automotive applications, such as in speed sensors and gear shift controls. Additionally, the CNW85 can be used in medical equipment applications, such as x-ray machines and EKG monitors, for providing isolation between different parts of the equipment, while still allowing signals to be transferred between them. Finally, the CNW85 is commonly used in industrial applications, such as in motor controllers.

Working Principle

The CNW85 works by using an opto-coupler. This consists of a light-emitting diode (LED) installed as the transmitter, and a phototransistor as the receiver. When a signal is applied to the LED, it emits light, which is detected by the phototransistor. This, in turn, activates the phototransistor, which activates a circuit. This allows signals to be transferred between two circuits, while providing electrical isolation between them. This is important, as it helps ensure that current from one circuit does not reach the other.

Conclusion

In conclusion, the CNW85 optoisolator is a device that is used to provide electrical isolation between two circuits, while still allowing for signal transfer. It is commonly used in various applications, such as in automotive and medical equipment, as well as in industrial applications. Its working principle relies on an opto-coupler, which consists of an LED and a phototransistor. When a signal is applied to the LED, it activates the phototransistor, which activates a circuit. This allows for signal transfer between two circuits, while maintaining electrical isolation between them.
