CMX-400 Series

Inertial measurement unit

The CMX-400M is a high-reliability low power strap-down inertial system providing accurate measurement of angular rate and linear acceleration in dynamic environments, with output data also available in delta theta and delta velocity format. The CMX-400M is offered in standard and high range sensor configurations to allow the best match for the user's application.

The CMX-400M includes Micro-Electro-Mechanical System (MEMS) gyros and accelerometers with high-speed DSP electronics to provide a fully calibrated dynamic measurement system in a small and rugged environmentally-sealed enclosure. The CMX-400M provides consistent performance in challenging operating environments and is user ideal for a wide variety of applications.
