Redundant Encoder Options

While most modern rotary encoders rely on non-contact sensing technologies and have high MTBF specifications, in critical applications it is still common to have redundant sensors required. When selecting a solution, a number of different criteria need to be considered and fortunately different solutions exist, making the task less daunting. Redundancy One of the first […]

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.

SSI Hardware

SSI hardware is fairly simple. Just use any RS-422 transceiver to generate the differential signals from/to the microcontroller port pins. Keep reading to learn about the different implementations of SSI hardware.
