Optical sensors are used in a variety of industries and applications, and photointerrupters are one example of the types of sensors that can be used to measure and detect changes in light. Specifically, the HOA1876-002 photointerrupter is a type of slot type sensor with transistor output that is designed to detect changes in light related to the presence, direction and speed of an object. This article explains the application field and working principle of the HOA1876-002 photointerrupter.

Application Field

The HOA1876-002 photointerrupter can be used in a variety of applications as a sensor to detect the presence, direction, and speed of objects. Typical applications include:

• Position sensing
• Counting
• Speed determination

The HOA1876-002 photointerrupter is especially suitable for applications which require large detection distances, high speeds and wide angles. It can be used in applications such as color marking systems, document processing, and label identification.

Working Principle

The HOA1876-002 photointerrupter consists of an infrared transmitting LED and an NPN silicon photo-transistor. The photointerrupter works by emitting a beam of infrared light from the LED. When the beam of light is interrupted by an object, the circuit is completed through the photo-transistor, providing an output signal. The output signal can then be used for various sensing applications.
