Robotics are one industry which uses a ton of motors and encoders to accomplish the automation required.   Read More »

Encoders are critical elements in a motion system because they provide position and/or velocity feedback to the motion controller, enabling the controller to close the positional control loop. For this post, we will focus on how encoders are summarized based on the type of movement measured.   Read More »

We have been researching the answer to that question for some time and although we have been able to gather some great information both from encoder manufacturers and my own research, at this point we do not have a definitive answer.   Read More »

Encoders come in many physical shapes, sizes, and configurations. Join us as we explore the various choices available for your US Digital encoder.   Read More »

Our incremental encoder modules have an LED on one side and a photo sensor on the other. A metal HubDisk is attached to a shaft on a motor and aligned in such a way that the transparent mylar disk passes between the LED and photo sensor in the module. A series of printed lines on the disk block light from the LED from reaching the sensor. The spaces between the lines do not.   Read More »

While we can't definitively tell you who created the first encoder, we can walk you through the early history of the industry and its key players.   Read More »

In this post we discuss how encoders can be used in everyone's favorite multi-prop flying objects. The growth of drone applications is always expanding.   Read More »
