General Description
The SCA100T-D07 is a 3D-MEMS-based dual axis accelerometer that enables tactical grade performance for
Inertial Measurement Units (IMUs) operating in tough environmental conditions. The measuring axes of the
sensor are parallel to the mounting plane and orthogonal to each other. Wide measurement range and bandwidth,
low repeatable temperature behavior, low output noise, together with a very robust sensing element and
packaging design, make the SCA100T-D07 the ideal choice for challenging inertial sensing applications.
