The 2227 Q-Module transforms SDI’s 1527 tactical-grade surface mount MEMS DC accelerometer into a compact, low-SWaP choice for customary quartz accelerometers. This unit maintains compatibility with standard pin configurations and form factors. Its robust design makes it particularly suitable for inertial and tilt applications in UAVs and unmanned systems, where a response to zero to medium frequencies is essential. It boasts exceptional long-term bias and scale factor consistency, along with minimal noise levels. Additionally, it operates effectively across a broad temperature spectrum of -55 to +125°C.
