DESCRIPTION
The KMA36 is a universal magnetic encoder for precise rotational or linear measurement. These 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 Resis-
tive (AMR) technology, the KMA36 is able to determine contactlessly 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 two-wire (SDA, SCL) communication
bus. Using the programmable parameters, the user can have access to a wide range of configuration to
ensure the maximum of freedom and functionalities.
