Inductosyn: End of an Era, New Opportunities or Both?

Recently, obtaining the Inductosyn and components for maintenance has become more difficult. For decades the Inductosyn from Farrand Controls / Ruhle Companies sat near the top of the rotary sensor hierarchy. Providing sub 2 arcsec (0.5 mdeg) accuracies, it combined the robustness of a resolver with the performance of the best optical encoders. Despite its shortcomings, it found plenty of customers, from airborne infrared and radar systems, to telescopes, satellite communication antennae (SATCOM), machine tooling and low-pressure vacuum chambers.

Encoder Technology Overview

Rotary encoders are used in a variety of applications to provide feedback on position, speed, direction, or angle. There are several different encoder types…

Redundant Encoder Options

In the world of rotary encoders, modern non-contact sensing technologies and high MTBF (Mean Time Between Failures) specifications are standard. However, in critical applications, redundant sensors are still a necessity. When selecting a solution, several criteria need to be considered, and fortunately, various options are available to simplify the task. Understanding Redundancy in Encoders The […]
