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.

Facing the Inevitable: Sensor Obsolescence, Mitigation Strategies, and Alternatives

Obsolescence. If its only difficulty was remembering how it is spelled it wouldn’t be so bad. And whether you’re trying to replace a sensor that has failed with age or are a manufacturer who can no longer source an important sensor, obsolescence of an inexpensive sensor can create extremely expensive headache. At Everight Position we help customers to understand the causes of sensor obsolescence, explore mitigation strategies and find alternative solutions.

Availability and the Three-Legged Stool analogy at Everight

While they may be small, the role of rotary encoders in spacecraft is vital, demanding a balance between performance, reliability, and the unforgiving environment of space. From NASA’s Robonaut II to automated material handling systems on the International Space Station, Everight has worked with engineers to put rotary encoders into ‘the final frontier.’

POSITAL UCD…H200 Through-hole Encoder

Over the past 15 years Everight Position has worked with a lot of unique sensors. But one of our favorites is the POSITAL UCD…H200. When looking back there are two things that make this sensor so special.
