Optical sensors are widely used in industrial and consumer applications because of their high accuracy and speed. Photointerrupters, in particular, are commonly used because of their use of light to detect the presence of an object in a given environment. The QVA21113 is a slot-type photointerrupter with a transistor output that is widely used in many different applications.

A basic photointerrupter consists of a light emitting diode (LED) and a phototransistor. The LED emits a light beam, which is detected by the phototransistor when an object passes through the gap between the LED and phototransistor. The output of the photointerrupter is typically either digital or analog. The QVA21113 is a digital photointerrupter, meaning that its output is either “on” or “off”.

The QVA21113 uses a slot-type design, which is characterized by a thin gap between the LED and phototransistor that allows the light beam to pass through. This type of design is often preferred for applications where a fast turn-on time is required, such as speed measurement or short-distance distance detection. The QVA21113 also has an internal reverse polarity protection feature, making it suitable for a wide range of applications.

The QVA21113 has a transistor output, which allows for control of a load such as a relay or motor. The output can be either NPN or PNP depending on the application. This type of output allows for greater flexibility as it can be used with a variety of external components. Additionally, the QVA21113 has a low power consumption rating and long operational life.

The QVA21113 is suitable for a variety of applications, including mechanical length measurement, object detection, automatic door openers, and counter mechanisms. It is also an ideal sensor for speed and proximity sensing. The QVA21113 can be installed in a wide range of environments, including indoor and outdoor settings as well as wet or dry conditions.

In summary, the QVA21113 is a slot-type photointerrupter with a transistor output that is suitable for a wide range of applications. It has a fast turn-on time, reverse polarity protection, low power consumption, and long operational life. It is an ideal sensor for speed and proximity sensing as well as for mechanical length measurement, object detection, automatic door openers, and counter mechanisms.
