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.

Seeing Is Believing: POSITAL 3D drawings now available for millions of encoders

POSITAL’s product finder has generated full specification custom datasheets for years. Rather than having to guess on specifications from a confusing product configurator, POSITAL provides part specific datasheets in real time for the given part number of interest.

NEW PRODUCT – VLH-35 ELECTRIC ENCODER FOR DC SERVO MOTORS

Netzer Precision Position Sensors is introducing the VLH-35, a new product designed to meet the needs of the servo motor industry and its requirements for the next generation of industrial rotary motion control.

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.
