4.4 Mechanical stress
In general, it is recommended to place the MTi 600
-series module in an area on the PCB where
mechanical stress is minimal. The following paragraphs describe possible causes of mechanical stress
and ways to reduce it.
4.4.1 Torque
The connector of the MTi-600 is soldered onto the PCB board which also contains the sensing
elements. Care should be taken to design the mounting such (see chapter 4.3) that there is no stress
on the connector when mounted on the PCB or connected with a ribbon cable. As any stress on the
connector could potentially result in torque on the PCB which can lead to unwanted biases and signal
noise.
4.4.2 Vibrations
The MTi 600
-series features an industry-leading signal processing pipeline (AttitudeEngine
TM
) which
rejects vibrations. For best results however, it is recommended that the MTi 600
-series is mechanically
isolated from vibrations as much as possible. Especially in applications where vibrations are likely to
occur, the anchor points of the PCB that holds the MTi
600-series module should be dampened. The
required type of dampening varies from application to application.
4.5 Magnetometer
The MTi 600
-series uses a 3D magnetometer for measuring the geomagnetic field. This part is sensitive
to magnetic disturbances. Magnetic disturbances can be calibrated for or identified and rejected by the
MTi, however it is recommended to avoid their influence during hardware integration.
4.5.1 Ferromagnetic materials
Ferromagnetic materials can be magnetized and the magnetic behaviour can change during operation.
This behaviour will influence the measurements of the 3D magnetometer of the MTi 600
-series.
Therefore, it is recommended to keep thes
e ferromagnetic materials away from the MTi 600
-series.
4.5.2 High currents
High current power lines on the PCB will introduce magnetic fields that may influence the measurements
of the 3D magnetometer of the MTi 600
-series. Place high current power lines away f
rom the MTi 600
-
series. Example: a power line with a current of 100
mA at a distance of 10
mm from the magnetometer,
will introduce an error of 2
µT.
