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 sens ing r ange.
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
unbalanc e is precise ly measured us ing a patented autoplex circuit. This signal is then converte d to a linear DC
output voltage, proportional to the angle of the rotor shaft. The digital circuit is extremely resistant to
environm ental disturbances suc h as EMI and R FI, and is c ompatib le for us e with m ost analog pos itio n feedb ack
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.

voltage or current output), R120LC (+5VDC operation, low cost) and R30D (bipolar DC operated RVDT).
