The KMA36 is a highly reliable universal magnetic position sensor
for precise rotational or linear measurement with a resolution up
to 0.04 degree. These digital position sensors feature a system-
on-chip technology that combines a magnetoresistive element
along with analog to digital converter and signal processing in a
standard small package. By using Anisotropic Magneto Resistive
(AMR) technology, the KMA36 is able to determine accurately and
non-contacting the magnetic angle of an external magnet over
360°, as well as the incremental position on a magnetic pole strip
with 5 mm pole length. Its sleep and low power mode as well as
automatic wake-up over I2C – make the KMA36 ideal for many
battery applications. Position data can be transmitted using a
PWM or digital two-wire (SDA, SCL) communication bus. Using
the programmable parameters of this digital position sensor, the
user can have access to a wide range of configuration to ensure
the maximum of freedom and functionalities.
Used as both a linear position sensor or a rotary position sensor,
these KMA36 magnetoresistive sensors designed by MEAS
(Measurement Specialties) are insensitive to magnetic drift due to
mechanical tolerances, changes in temperature or thermal stress.
The maintenance-free operation and high bandwidth of this
universal magnetic encoder makes it a good choice for dynamic
applications in harsh environments.
