TMR: A New Revolution in Magnetic Rotary Encoders

Abstract: Tunnel magnetoresistance (TMR) sensing is an exciting new chapter for magnetic-based rotary encoders. Requiring less current, while offering higher signal strength, many of the inherent short comings of Hall Effect based sensors can be addressed.

Position Sensors for Hazardous Locations

When choosing components for a hazardous environment it is important to have a trusted partner. For over a decade engineers have relied on Everight Position for rotary, linear and tilt sensors for these challenging applications.

Tiny Tech, Big Impact: Rotary Encoders Are a Critical Link the Agrobot Revolution

A recent GlobalData report highlights the impressive growth of the robotics industry in agriculture (reaching $218 billion by 2030), a key component behind this revolution often goes unnoticed: the rotary encoder. These unsung heroes convert rotational motion into precise electrical signals, playing a vital role in ensuring the smooth, accurate movements of agricultural robots.

Accuracy, Resolution and Repeatability

There are several key terms that are critical to specifying the optimal position sensor for a given application. This application note defines these key terms and how they relate to the sensor’s role in the overall system performance. It is important to consider that precision is very much a system issue and can be dominated by mechanical errors such as eccentricity. This paper discusses the most significant mechanical error for rotary applications (eccentricity) and presents eccentricity tolerant position sensor solutions.
