DESCRIPTION

The MA710

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 MA710 is particularly suitable for low

magnetic

field

applications:

side-shaft

configuration or the use of non-rare earth

magnets.

The MA710 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 the

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,

and

magnetic

field

detection

thresholds.
