The TBMA is a test board for the MagAlpha magnetic position sensor family. The TBMA allows users to run and test the MagAlpha sensor quickly. TBMA boards exist in two different formats: round (RD) and long (LT). In the RD format, the sensor is mounted in an end-of-shaft configuration. In the LT format, the sensor is mounted on the edge of the board and can therefore be used in both side-shaft and end-of-shaft configurations.

The TBMA is compatible with the Macom kit, offering seamless connection and operation of the MagAlpha and allowing users to evaluate MagAlpha functionalities and performances with their own set-up.

Contrary to the EVMA, the TBMA only includes the assembled board with the sensor and decoupling capacitors. It does not include connectors.


  • Round Board Format for End-of-Shaft Mounting
  • Long Board Format for Side Shaft and End-of-Shaft Mounting
  • Compatible with MagAlpha Communication Interface Kit (EVKT-MACOM)


  • IC Supported 1MA850




The MagAlpha MA850 is a simple-to-use magnetic angle encoder designed to replace analog potentiometers or rotary switches. The sensor detects the absolute angular position of a permanent magnet attached to a rotating shaft and outputs a PWM waveform with 8-bit resolution.

The user has wide flexibility in terms of magnet shapes and configurations. Typically, the MA850 is used with a diametrically magnetized cylinder of 3mm to 8mm in diameter. 

The MA850 features programmable magnetic field strength thresholds which allow implementation of a push or pull button function. When triggered, these are readable as register bits and also output as two logic signals.

On-chip non-volatile memory provides storage for configuration parameters including the reference zero angle position and the magnetic field detection threshold settings.
