Optical sensors are widely used in a variety of applications such as sensing presence, speed, and distance. A photointerrupter is a type of optical sensor that uses light to detect the interruption of the LED beam. The HOA0872-N55 is a slot type photointerrupter that has a transistor output and is capable of sensing a variety of objects and objects sizes. This article will discuss the application field and working principle of the HOA0872-N55.

Application Field

The HOA0872-N55 can be used in a variety of applications including object detection, signal transmission, and counter applications. It is designed for use in industrial automation, automatic door systems, packaging machines, user input detection, and rotary encoder applications. The HOA0872-N55 is capable of accurately detecting objects such as paper, plastic, metal, and wood. It is also capable of detecting objects of various sizes from 0.15mm - 3mm and provides detection resolution up to 0.25mm.

Working Principle

The HOA0872-N55 consists of an LED, a photo transistor, and a slot-shaped optical element. The optical element is designed to block out the light from the LED until an object interrupts the slot. When the object passes through the slot, the LED light is able to pass through the slot and activate the photo transistor. The photo transistor is then able to detect the presence of the object and output a signal to the application. The output from the HOA0872-N55 is a transistorized output.

Conclusion

The HOA0872-N55 is a slot type photointerrupter that has a transistor output and is capable of detecting a variety of objects and objects sizes. It is ideal for use in industrial automation, automatic door systems, packaging machines, user input detection, and rotary encoder applications. The HOA0872-N55 works by using an LED, a photo transistor, and a slot-shaped optical element. The photo transistor is then able to detect the presence of the object and output a signal to the application. This makes the HOA0872-N55 an ideal choice for a wide range of applications.
