VS PRODUCT FAMILY

VS9000

The trusted partner for the most

demanding applications since 2008

Large frequency response and

performance stability, as well as

low power consumption

VS1000

A new reference for low to medium

frequency MEMS sensing

Highest performance stability and

shock resistance, as well as the

lowest non-linearity and noise

in the marketplace
