Optical sensors are used in a range of engineering applications, including medical, vehicle, and industrial automation applications. Photointerrupters like HOA1873-013 are well suited for applications that require precise timing and high accuracy in controlling movements. The HOA1873-013 is a slot type optical photointerrupter, which has a transistor output. This article will provide an overview of the HOA1873-013 photointerrupter, its applications, and the working principles that make it an effective tool for industrial automation.

Applications of HOA1873-013

The HOA1873-013 is suitable for applications where precise timing and high accuracy is desired in controlling the movements of objects. Some of the more common applications include the control of conveyor belts, shutters, or doors in industrial automation, or any application that requires the detection of an object or a moving object. This photointerrupter can also be used as a door/window sensor for intrusion detection. It can detect the presence or absence of an object within the sensing region, or even detect the speed of the object.

Working Principle of HOA1873-013

The HOA1873-013 slot type photointerrupter uses the principle of light interruption to sense and differentiate between objects and moving objects. An infrared light emitting diode (LED) is used as the light source and an integrated phototransistor is used as the detector. The phototransistor works to detect the presence or absence of an object within the sensing region, while the LED transmits infrared light to the phototransistor when the object is within the sensing region. When an IR LED is illuminated and the phototransistor is exposed, the current flow is measured from the phototransistor, which increases when the IR LED is occluded.

The HOA1873-013 photointerrupter is also capable of providing a digital output, which can be used to control external circuits or provide a digital signal. This is enabled by a logic circuit which is connected to the phototransistor and IR LED, and the circuit works by detecting a change in current when the IR LED is occluded. When an object is detected, it sends an output signal to the logic circuit which then triggers an output signal to activate the external circuit.

Advantages of HOA1873-013

The HOA1873-013 photointerrupter offers several advantages for applications in industrial automation. It is capable of providing high accuracy and precise timing control when detecting objects, as well as a digital output signal. The photointerrupter also offers a wide operating voltage range, making it suitable for use in a range of applications. In addition, the HOA1873-013 is extremely reliable and offers a long service life.

Conclusion

The HOA1873-013 slot type optical photointerrupter is an effective tool for industrial automation applications. It offers accurate, timely detection of objects and is capable of controlling external circuits with its digital output. The photointerrupter also offers a wide operating voltage range and is extremely reliable. If you\'re looking for an optical photointerrupter that can effectively control movement in industrial automation applications, the HOA1873-013 is an ideal choice.
