R60D – DC Operated Rotary Variable Inductance Transducer  Lower cost than RVDTs  Bipolar DC operation  ±60 degree sensing range  High level VDC output  Light-weight  Non contact design  Size 11 servo mount  Anodized aluminum housing DESCRIPTION The R60D RVIT (Rotary Variable Inductance Transducer) is a DC operated non-contact angular position sensor. Operating on a ±15VDC supply, the R60D provides a smooth ±7.5VDC output proportional to angular position over a ±60 degree sensing range. The RVIT proprietary design utilizes a set of four printed circuit coils and a light-weight conductive spoiler to achieve superior performance with a low moment of inertia. During operation, the light weight spoiler rotates with the transducer shaft, differentially altering the inductance of the printed circuit planar coils. The resulting unbalance is precisely measured using a patented autoplex circuit. This signal is then converted to a linear DC output voltage, proportional to the angle of the rotor shaft. The digital circuit is extremely resistant to environmental disturbances such as EMI and RFI, and is compatible for use with most analog position feedback systems. Calibrated for use over the full ±60 degree sensing range, the R60D offers exceptional performance at a cost effective price. It also features a wide operating temperature range, infinite resolution, and an extremely long rotational cycle life.
