SPEA high g test units are designed for the best-performance production testing of high-acceleration MEMS inertial sensors, ideal for automotive components: A high-precision actuator shakes the devices applying up to 28g of acceleration, at up to 120Hz of frequency, under the required temperature conditions.

MEMS devices can be stimulated in XYZ simultaneously, saving on cycle time numbers with all related advantages in terms of test time (especially when several test passages at temperature are required) and minimized risk of device damage.

The modules offer top performance level, with less than 1.5% harmonic distortion at 28g / 90 Hz stimulation. The actuator is mounted on damping supports, while the unit chassis is made of natural granite, so as to offer best shake characteristics.
