Synchros are typically used to feedback angular position of rotating equipment and are considered a traditional form of inductive angle encoders. Zettlex inductive encoders are based on similar induction principles as synchros and offer reliable and highly accurate operation in harsh environments.
Zettlex encoders incorporate printed circuit boards as their main components, resulting in smaller, lighter and less costly devices. Unlike synchros, they do not require any electrical connection to their rotors.
