Optical sensors are a type of transducer which convertelectromagnetic signals into an electrical signal. There are many different varieties of optical sensors, and Photointerrupters – Slot Type – Transistor Outputs are among the most widely used. One such device is the QVB21313, which is a standard-type photo interrupter with two slots and a transistor output.

The QVB21313 is a passive opto-electronic device, meaning that it does not require any external power. This makes it an efficient choice for a variety of applications, such as detecting the presence of an object in an automated environment. It can also be used in linear positioning applications, where it is able to measure movement with accuracy and precision.

The primary components of the QVB21313 are the two slots, the emitter, and the receiver. The light signal is emitted from the emitter into one of the slots, where it is then interrupted or blocked. This interruption is detected by the receiver, which then sends an electrical signal to the transistor output. This electrical signal can then be used to activate or deactivate various components in the system.

The working principle of the QVB21313 is based on the principle of photo interrupters. When the light signal emitted from the emitter is blocked by an object placed in the slot, the collector-emitter current of the transistor is interrupted. This interruption is detected by the receiver, which then triggers the transistor output. This output can then be used to activate other components in the system.

The QVB21313 is a versatile device that offers a range of applications. It can be used in industrial automation systems to detect the presence of objects, or in linear positioning systems to measure movement with accuracy. It can also be used in consumer electronic devices, such as clocks and digital watches. The QVB21313 is a reliable and cost-effective way to achieve precision detection and actuation.
