QVE00832C is an example of a specific type of slot type photointerrupters that features a built-in circuit for switching with transistor output. It is a two-headed IR LED optical sensor with a 7mm [ 0.275 inch ] slot width.

Application Field of QVE00832C

QVE00832C is designed for small and miniature electronic devices, and its size helps to provide the highest degree of reliability and control. It is widely used in automobile charging equipment, medical and health products, 3C consumer electronics, centralized control systems, measuring instruments, and alarm systems. In addition, due to its small size, it is also ideal for use in high speed applications.

Working Principle of QVE00832C

The QVE00832C is a type of photointerrupter that uses two LEDs in the form of an emitter and detector. The emitter is installed at the end of the slot, and the IR light will be blocked when an object enters in the slot. When the light path is blocked, the transistor will be triggered and the output signal changes. The two LEDs are connected in series with a transistor connected to the collector of the LED, which acts as a control signal for the output. When there is no interruption, the two LEDs are connected in parallel with the collector of the transistor, and the transistor is open. When the LED is blocked, the transistor is driven on, causing a change in the output signal.

Advantages of QVE00832C

The QVE00832C use an effective shutdown circuit that prevents false triggering from excessive light intensity. Besides, it features a fast response time, which is only 4.5 microseconds, making it ideal for high speed applications. In addition, its built-in output protection circuit allows the transistor to be driven directly without extra protection components.

Conclusion

QVE00832C two-headed transistor output slot type photointerrupter is suitable for precision positioning and movement detection applications. It is capable of providing reliable and noiseless operation with fast response time, and its small size make it appealing for many types of electronic devices. The built-in protection circuit helps to reduce the number of external components needed, making it an ideal choice for reliable operation.
