Optical Sensors - Photointerrupters - Slot Type - Transistor Output

HOA0860-N55 is the model number of a linear opto-isolator developed by Sharp Corporation. It is integrated with an IR emitter and phototransistor pair, each housed in a discreet package. HOA0860-N55 is a specific type of optical sensor that belongs to a larger class called photointerrupters. Photointerrupters are optical sensors that use an alternating light source and an integrated photodetector in order to detect the positioning of an object.HOA0860-N55 is among photointerrupters called slot type, which make use of a very small gap between a pair of contacts. When an object passes through the gap, the LED emits light that is on one side of the contacts and then detected by the phototransistor on the other side. This results in a change in voltage. Slot type photointerrupters also operate with a resistor in series with the LED. When the object interrupts the light, the voltage is increased, causing the transistor to turn off.When it comes to HOA0860-N55 specifically, it is featured with a very low voltage drop across the LED, which allows for a high signal processing speed. Additionally, it is configured with a high collector-emitter voltage of 50V which allows it to drive a relay or solenoid. This improves its suitability for use in applications that require quick response, such as the automated counting systems that are prevalent in industries.HOA0860-N55 also features an output type of transistor output. This type of output is the greatest asset of HOA0860-N55, as it allows the user to detect a single pass of light and to switch various circuits. Furthermore, it offers maximum controllability as the initial logic voltage is determined by the drive current of the transistor.The working principle of HOA0860-N55 is relatively straightforward. When the integrated LED is powered on, it emits light to the phototransistor placed on the other side of the gap. When an object interrupts the light, the phototransistor turns off, changing the voltage and triggering the output.HOA0860-N55 can be used in an array of applications, including factory automation, electronic office equipment, and many more. It is ideal for applications that require extensive measurements of a complex phenomenon. Other applications of this opto-isolator include the regulation of motors, automated counting systems, and positioning machines.With its low power consumption and reliable performance, HOA0860-N55 is widely used and is known to be a reliable optical switch that can be used in industrial settings. Furthermore, it is also relatively easy to repair and maintain. With its superior features, HOA0860-N55 is becoming an increasingly popular option to choose for a variety of applications.
