From pan-tilt-zoom cameras to the most highly sophisticated mini robots on the market, a wide array of today’s technologies incorporate some form of motion control system.
At the heart of these devices and machines is a relatively unknown technology referred to as the reflective encoder.
Basically, the reflective encoder is tasked with providing feedback of motion information vis-à-vis a servo mechanism for the purpose of ensuring utmost accuracy in terms of motion control. These components are small in terms of size and use relatively little power compared to transmissive encoders.
As a result of these favorable specs, reflective encoders are considered ideal for use in many forms of miniaturized motion control systems, and are often embedded in stepper motors, electrical actuators, and piezoelectric drives.
Avago Technologies provides the industry with an array of motion encoder solutions. The San Jose-based company takes pride in providing the industry with the smallest form factor and most comprehensive offering of miniature reflective encoders to not only meet today’s needs, but prepare engineers and designers for tomorrow’s demands.
