Product Description

The R120LC RVIT (Rotary Variable Inductance Transducer) is a cost efficient, DC operated non-contact angular position sensor. It provides a smooth 0.5 to 4.5VDC output, ratiometric to the supply voltage and proportional to angular position over the 120 degree sensing range. The R120LC utilizes non-contacting, differential inductive technology, and does not suffer the wear problems experienced by potentiometers.

The R120LC 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 provides resistance to environmental disturbances such as EMI and RFI, and is ideally suited to the most rigorous industrial applications.

Calibrated over the full 120 degree sensing range, the R120LC 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.
