2227 Tactical-Grade Inertial Navigation MEMS DC Accelerometer
The 2227 Q-Module converts SDI's 1527 tactical-grade surface mount MEMS DC accelerometer into a low-SWaP drop-in replacement unit for legacy quartz accelerometers, featuring industry-standard pin and form factor compatibility. The rugged sensor solution is ideal for UAV and unmanned systems inertial and tilt applications that require zero to medium frequency response, excellent long-term bias and scale factor repeatability, and low noise. It also features a wide operating temperature range of -55 to +125°C.
