Zettlex IncOders position sensors use noncontact inductive technology for precision angle measurement. Their printed circuits make for compact, accurate, lightweight and robust position sensors with no contacts, no delicate parts and no maintenance. Suitable for harsh environments, the sensors have two main parts—a stator and a rotor—each shaped like a flat ring. The large bore makes it easy to accommodate through-shafts, slip rings, optical fibers, pipes or cables. The stator contains the electronics to receive power and generate an output signal. This output signal shows the true absolute angular position of the rotor relative to the stator without the need for motion.
