CN1 CN2 TBMA Test Board for MagAlpha Sensors User Guide DESCRIPTION FEATURES The TBMA is a test board for the MagAlpha Round Board Format for End-of-Shaft magnetic position sensor family. The TBMA Mounting allows users to run and test MagAlpha sensors Long Board Format for Side Shaft and End- quickly. TBMA boards come in two different of-Shaft Mounting formats: round (RD) and long (LT). In the RD Compatible with the MagAlpha format, the sensor is mounted in an end-of-shaft Communication Interface Kit (EVKT- configuration. In the LT format, the sensor is MACOM) mounted on the edge of the board and can be APPLICATIONS used in both side-shaft and end-of-shaft configurations. Servo Drives Robotics TBMA test boards are compatible with the Automotive MACOM evaluation kit, offering seamless BLDC Motor Commutation connection and operation of MagAlpha sensors, Encoders and allowing users to evaluate MagAlpha functionalities and performances with their own All MPS parts are lead-free, halogen-free, and adhere to the RoHS directive. set-up.

USER GUIDE TBMA TEST BOARD FOR MAGALPHA Board Types Different board types are available, and each has a different schematic and layout design (see Table 1 on page 3). The board type to use is determined by the selected sensor part number. Each board type is also available in two different formats: a round test board (RD), or a long test board (LT). The board part number specifies which format is used: TBMAXXX-Q-RD-XXX = Round test board TBMAXXX-Q-LT-XXX = Long test board Both RD and LT board formats can be used for end-of-shaft configurations where the sensor is positioned at the end of the motor or knob shaft. For side-shaft configurations where the sensor is positioned perpendicularly to the motor or knob shaft, only the RD board format can be used.
