DESCRIPTION

The MAQ430 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 0 to 60,000 rpm.

The

MAQ430

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 MAQ430 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 of axial movements or for diagnostics.

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.
