Inside the E4T Miniature Optical Kit Encoder, shown above, is a very small disk. During production, operators had great difficulty transferring the disks by hand.

When US Digital released the E4T Miniature Optical Kit Encoder it needed to update manufacturing procedures to better handle the miniaturized encoder disks. The company decided to use automation and built the delta robot system above. It speeds up manufacturing and frees staff to spend time on higher-level tasks. New Miniature Encoder Disks Caused Production Difficulties for...   Read More »

Disk Resolutions

With some optical encoders you can literally see the resolution right on the encoder disk. Look at the disks above and notice how closely the lines are spaced. Encoder resolution is defined as the smallest distance that can be measured or observed. However, it can be used in three different ways within the same motion control system—this can lead to confusion. In this post,...   Read More »

Figure 1

So far in this blog we've written about encoders that are moved by something else. They're attached to a motor shaft, or a linear actuator, or conveyor belt. Their job is to report their position as they're moved by an external force; other than that, they're just along for the ride. Well, sometimes - the encoder is the ride! Sometimes the encoder moves first, and everything else reacts to...   Read More »

DWG 001: Analog Voltage Output

In an earlier post to this blog, we introduced Absolute Encoders. We illustrated the differences between absolute and incremental encoders, and showed that an absolute encoder can give a unique report for each different position on the encoder disk. But we didn't talk about what that report looks like. Looking back to incremental encoders for a moment, each part of their output waveform looks...   Read More »
