Optical sensors have been widely used in many fields. In this article, we will talk about the OPB901L55, a photointerrupter slot type logic output.

Photointerrupters are a type of optical sensor that use light emitted from an LED to detect the presence of an object passing between the LED and a photosensor. The OPB901L55 is a type of slot-type photointerrupter, which means that it has a slot slit between the emitter and receiver of light. The OPB901L55 is designed to detect objects which are placed in an area from 1.5mm to 3.5mm away from the slot.

Photointerrupters such as the OPB901L55 are often used in industrial applications to detect the presence of objects or materials. It can detect small changes in the light emitted from the LED and is precise enough to detect the presence of objects even if they are moving.

The working principle of the OPB901L55 is fairly simple. The device emits a beam of infrared light through the slot, and when an object passes through the slot, some of the infrared light is blocked. This reduces the amount of light received by the photointerrupter\'s sensors, and the device detects this change as an object is placed in the slot. The device then sends a signal to the controller, which then does something based on that signal.

The OPB901L55\'s logic output makes it easy to use with a wide range of controllers, as it can be connected to a digital logic input. It is compatible with a wide range of microcontrollers, including PICs, AVRs, timer chips, and other microprocessors. The device is also equipped with a driver LED, which allows it to be used in a circuit with a larger LED or other light sources.

The OPB901L55 is typically used in industrial or robotics applications where speed and accuracy are paramount. Some common applications include the detection of materials in a conveyor belt, the detection and counting of objects on a production line, or the detection of a person in an area where they should not be. It can also be used in robotics applications such as collision avoidance, or for the detection of objects on a robotic arm.

The OPB901L55 is a low-cost and reliable solution for optical sensing needs. It is easy to use and has a wide range of applications in industrial settings. Its logic output makes it simple to integrate with a variety of controllers and other systems, making it a great choice for a wide range of applications.
