American Bright IR Series
American Bright offers a full line of infrared devices for analog and digital controllers.
This line includes:
- discrete photo emitters and phototransistors with various lens colors;
- infrared receiver modules, which integrate a phototransistor and IC that can independently receive infrared light and output TTL-compatible signals
- photo interrupters, which integrate an emitter and one or more phototransistors facing each other in a single package and function as an optical switch when an object comes between them;
- and photocouplers or photo-isolators, which also include an emitter and phototransistor that convert electrical signals to light pulses to transfer information between two isolated circuits.
American Bright’s line includes options for through-hole and surface mount packages as well as a wide range of peak wavelengths. These infrared devices are commonly used in remote controls, object detection, motion sensing, and many other applications.
For example, photo interrupters are commonly used in robotics applications. An encoder disk is mounted on a motor shaft, with the channel of the photo interrupter surrounding the edge of the encoder disk. As the motor rotates, slots in the disk allow light to pass from the emitter to the receiver, toggling the output of the photo interrupter. The controller can count these changes to accurately control the robot’s position and speed. For more information, visit American Bright.
