Optical Sensors are used in an array of applications, and one such device is a QVA11334 photointerrupter that falls under the slot type category, which features a transistor output. This type of photointerrupter performs a variety of tasks, as the light it detects is rapidly interrupted by an extended aperture.The QVA11334 photointerrupter is used for detection in motors controlling drives and motors, as well as in various types of industrial labeling machines and for color copy machines. It also acts as an integral component for a variety of airborne applications.

Inside the QVA11334 photointerrupter, two components are used to facilitate the signal detection. The first is a light emitting diode (LED), which is used to produce a light signal that will be detected by the second component, the phototransistor. The phototransistor will convert the light signal into an electrical signal that can be further processed by other electronics.

The QVA11334 photointerrupter is also equipped with an integrated optical lens, which helps to spread the light signal evenly throughout the entire sensing area. Additionally, its features make the component eye-safe, making it suitable for use in medical applications.

The QVA11334 photointerrupter also features a dark on output configuration, which is an ideal choice for applications like industrial motors, conveyors, and labeling machines. This means that, when the light emitted by the LED is blocked by the extended aperture, it signals the transistor to turn off, which in turn signals the device to turn off. On the other hand, when the light emitted by the LED is not blocked, it signals the transistor to turn on, which in turn signals the device to turn on.

For proper operation, the QVA11334 photointerrupter requires an ambient illumination of 10,000 lux or less, which is considered a low-light condition. The QVA11334 photointerrupter can also operate at temperatures ranging from -40 to +85 Celsius, making it suitable for many different types of applications. Furthermore, the rated current of the QVA11334 photointerrupter is 150mA, meaning that it can handle high current demand applications as well.

In summary, the QVA11334 photointerrupter is used to detect signals in motors controlling drives and motors, as well as in various types of industrial labeling machines and color copy machines. It features a dark on output configuration, a low ambient illumination requirement, and an operational temperature range of -40 to +85 Celsius. Additionally, it features a rated current of 150mA, making it suitable for high current demand applications.
