An optical sensor is a device that converts light into electronic signals. The OPB880T11Z is an example of such a device, as a photointerrupter, more specifically of the slot type, with a transistor output. Photointerrupters work by detecting the presence or absence of an object using a light source and a light detector. They are used for a variety of applications, including counting, positioning and detecting the end of travel.

Working Principle

The OPB880T11Z works by using an infrared (IR) LED emitter mounted on one side of a slot and an IR transistor mounted on the opposite side. When there is no object crossing the slot, the IR light emitted from the LED will be detected by the IR transistor. This will cause a high voltage signal to be sent to the output. When an object blocks the slot, the IR light from the LED is blocked and the transistor will no longer detect it. This will cause the output voltage to drop to a low signal.

Applications

The OPB880T11Z can be used for a variety of applications, such as:

• Detecting the presence or absence of an object such as paper or cardboard.
• Counting objects that pass through a predetermined area.
• Positioning and detecting the end of travel for applications such as electronic motors, conveyors, and other automated mechanisms.
• Detecting and measuring changes in air pressure in process control systems.

It can also be used for object identification, such as for security purposes or for differentiating between similar objects.

Advantages

The OPB880T11Z offers several advantages over other types of optical sensors. Its use of an IR LED and IR transistor gives it faster response times and wider dynamic range. These features make it ideal for use in applications such as position sensors, motor controls, and process control systems. The device is also easy to set up and install, as well as easy to maintain.

Conclusion

The OPB880T11Z is an essential device in any optical sensing application. Its fast response time, wide dynamic range, and easy setup and maintenance make it the ideal choice for a variety of applications. It can accurately detect and count objects, as well as detect and measure changes in air pressure. These features make it perfect for use in process control systems, security and identification, and motor control.
