Corona Virus: Avoid Encoder Supply Chain Disruption – Find Replacements Quickly

March 16, 2020

The rapid spread of Coronavirus in China has been a cause of major supply chain disruption for many US manufacturers. For OEMs whose equipment uses incremental optical encoders to manage AC/DC motor speed, acceleration, and related equipment position, it has become a significant issue for overseas encoder manufacturers such as...

Miniature Rotary Encoders with Built-In Commutation

February 13, 2020

Automated equipment designers in many medical, industrial and military sectors are constantly working to reduce the working envelope of the equipment they produce. Whether it is for robotic or cartesian systems, motors and motion control systems are shrinking, while motor torque and accuracy requirements are increasing. Compact and miniature rotary...

Incremental Rotary Encoders for Automated Guided Vehicle (AGV) Control

January 15, 2020

Warehouse automation systems have progressed dramatically over the last decade thanks to improvements in software, actuation, sensing, communication and control technology. AGVs have benefited greatly from these advances, and as a result are being applied to a broadening range of applications. AGVs have defined paths or areas within which they...

What is a Transmissive Rotary Encoder?

July 1, 2019

A transmissive rotary encoder, also known as a shaft encoder, is an optical, electromechanical device that is used to measure and control rotational motion in a very broad range of industries and applications. Internal sensors detect interruptions in a light source and send corresponding analog or digital signals to system...

Expanded Bore Options for HR12 Optical Encoder

January 3, 2019

As outlined in a previous post, our HR12 optical encoder is a popular choice for HEDS replacement. We also have found that the HR12 serves as a great HEDM replacement. Our HR12 rotary encoder boasts a wide range of line count options from 24 to 20,000 PPR as well as many...
