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.

When COTS Isn’t Enough: Why You Need a NIST 800.171 Compliant Supplier Like Everight Position

The COTS Conundrum: In today’s digital landscape, Commercial Off-the-Shelf (COTS) sensors seem like an easy button for compliances purposes. They’re readily available, cost-effective, and offer familiar functionality. But when it comes to identifying strategic suppliers, COTS alone isn’t enough.

NASA- Robonaut 2

Robonaut 2 (R2) is a state-of-the-art, highly dexterous anthropomorphic robot. The robot is designed to work with humans and has the ability to use the same workspace and tools.

The robot joints incorporate dual encoders for position and torque feedback while performing in a dynamic application, vibration, shocks, and wide temperature range.

Why Holistic Encoders are More Accurate

All absolute rotary encoders have a rotor which is attached to the rotating shaft and a stator which is attached to the housing holding the shaft. The interaction of these two components produces a measure of the shafts rotational angle. The most important parameters of absolute rotary sensors are resolution, accuracy and tolerance to misalignment of the rotational axes.
