MagAlpha MA330

14-Bit, Digital, Contactless Angle Sensor

with ABZ & UVW Incremental Outputs

DESCRIPTION

FEATURES

The MA330 detects the absolute angular

position of a permanent magnet, typically a

diametrically magnetized cylinder on a rotating

shaft. Fast data acquisition and processing

provide accurate angle measurement at speeds

from 0rpm to 60,000rpm. The digital filtering is

adjustable to optimize control loop performance

when used in servo applications.

Package

•

The MA330 supports a wide range of magnetic

field strengths and spatial configurations. Both

end-of-shaft and off-axis (side-shaft mounting)

configurations are supported.

•

The MA330 features magnetic field strength

detection with programmable thresholds to allow

sensing of the magnet position relative to the

sensor for creation of functions such as sensing

axial movements or for diagnostics.

APPLICATIONS

On-chip, non-volatile memory provides storage

for configuration parameters, including the

reference zero angle position, ABZ encoder

settings, UVW pole pair emulation settings, and

magnetic field detection thresholds.
