KMT32B

Magnetic Angle Sensor

TDFN

SPECIFICATIONS



AMR Sensor with 180° period

high accuracy

high resolution

for the use at moderate field strengths

tiny TDFN package

ROHS & REACH compliant

SO8

The KMT32B is a magnetic field sensor based on the

anisotropic magneto resistance effect, i.e. it is sensing the

magnetic field direction independently on the magnetic field

strength for applied field strengths H>25 kA/m. The sensor

contains two parallel supplied Wheatstone bridges, which enclose

a sensitive angle of 45 degrees.

A rotating magnetic field in the surface parallel to the chip (x-y

plane) will therefore deliver two independent sinusoidal output

signals, one following a cos(2) and the second following a

sin(2) function,  being the angle between sensor and field

direction (see Figure 2).

FEATURES



Contactless angular position,

ideal for harsh environments

Design optimized for linearity



High accuracy

The KMT32B magnetic field sensor is suited for high precision

angle measurement applications at a regular field strength of H₀

≥ 25 kA/m (generated for example with magnet 67.044 from

Magnetfabrik Bonn at a distance of 5.2 mm at room temperature).

With reduced accuracy, the sensor KMT32B may be used with a

field strength of H₀≥ 14 kA/m (at room temperature; be aware of

the influence of the earth magnetic field!). Most magnets show a

decreasing field strength with temperature while the magnetic

field direction is unchanged.

Low cost, low power

Self diagnosis feature

Attractive SMD packages

User has complete control over

signal evaluation



Extended operating temperature

range

(-40 °C to +150 °C, +160°C on

request)



REACH & RoHS compliant (lead

free)
