Optical Sensors are devices used to detect changes in light intensity. One type of optical sensor, known as a photointerrupter or slot type sensor, can be used to detect the presence or absence of an object. The HOA6972-N55 is an example of such a device. It is an infrared light emitting diode (IRED) and NPN transistor logic output photointerrupter, which can be used in a broad range of applications.

The HOA6972-N55 provides a cost-effective solution for detecting objects that interrupt a light beam or that pass through a gap. It consists of an IRED and a NPN transistor logic output that can be used to switch a device in response to an object interrupting the light path. The device can be used in a variety of applications, ranging from industrial automation and detection systems to consumer electronics technology.

The working principle of the HOA6972-N55 is based on the interruption of the light path. When an object passes between the IRED and the phototransistor, the light that reaches the phototransistor is blocked and the output is switched to its low state. When the object is removed, the phototransisor again recieves light and the output returns to its high state. The device operates with a 3.3V to 5V supply in the range of -30°C to +90°C.

The HOA6972-N55 is ideal for applications where a small, low-cost optoelectronic device is required to detect the passage of an object such as a photograph or document. It can also be used as an industrial automation device, for sensing or counting objects such as parts or products. It can be used in serial port bi-directional communications circuitry, as well as for security applications such as rolling code remote control systems.

The HOA6972-N55 is a reliable and cost-effective solution for a wide range of applications and environments. Its small size and low power requirements make it an ideal choice for embedded applications. It is suitable for both automotive and industrial applications, as well as for consumer electronics. With its wide operating temperature range and long life expectancy, the HOA6972-N55 is a great choice for any application where reliable detection of objects is required.
