How to clean encoder disks and linear strips

What is the best way to clean rotary encoder disks or linear encoder strips of small dust and particles? When it comes to our optical and transmissive encoders, the best option is probably to actually just leave things alone. Why is that? Our encoder modules use an LED and...

PCN 6644 - 2" Hub/Disk Assembly Screw Change

Resolution, Accuracy, and Precision of Encoders (1)

When you’re choosing an encoder for a motion control system, you’ll be faced with numerous technical terms. The amount of data available can be overwhelming. Which critical terms should you focus on first, and which can be deferred? This paper looks at three important...

How to pick the right encoder for your next project

You’re building a new machine, an electromechanical system, and you need to precisely control its motion. It’s critical that you get continuous positional feedback from the parts that move. You think you may need an encoder. A quick search shows a huge range of encoder choices....

Encoder Basics for Motion Control Engineers

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 control loop. The number of applications that require encoders is extensive and the types and sizes of...
