The TD5207 from Micronor, a non-metallic fiber optic rotary encoder, has been designed especially for use in motion control systems operating in extreme electromagnetic fields. Medical diagnostic and research applications include MRI (magnetic research imaging) or NMR (nuclear magnetic resonance) tomography imaging systems. The encoder also serves as the control feedback for pneumatic or hydraulic drive systems operating in these same extreme environments and applications. Based on proprietary, patented ZapFREE™ fiber optic rotary encoder technology, the all-optical, passive TD5207 encoder/ sensor is identical in design to Micronor’s MR3XX series fiber optic encoders except for its construction of non-metallic materials. The ZapFREE™ system utilizes telecom-proven WDM (wavelength division multiplexing) technology by assigning each internal optical path (A or B) to a wavelength so that all wavelengths/paths can be combined onto a single fiber. The single-fiber interface makes the installation and connection of the encoder both exceedingly simple and elegant in contrast to the bulky, multi-conductor shielded cabling that conventional optical rotary encoders or even resolvers require. These fiber optic sensors overcome the limitations of conventional optical rotary encoders that can be affected by EMI/RFI, ground loops, lightning, and ESD.
