SDC500 MEMS Inertial Measurement Unit (IMU) (License Free)

Ideal for High-Precision Commercial & Industrial Applications
Systron Donner Quartz MEMS
The compact SDC500 Quartz MEMS Inertial Measurement Unit (IMU) meets commercial aerospace, industrial and marine application needs globally. It is available in several performance-cost options ranging in accuracy from precision 1°/hr gyro and 1 mg accelerometer to 20°/hr gyro and 5 mg accelerometer bias over temperature, shock, and vibration environments. This enables customers to select the SDC500 version that meets their specific performance and budget requirements from near tactical grade to high-performance commercial/industrial grade. The SDC500 IMU is constructed with EMCORE’s latest generation quartz gyros, quartz accelerometers, and high-speed signal processing to achieve outstanding precision performance. The SDC500’s breakthrough gyro design retains Quartz MEMS sensitivity and linearity and greatly improves noise immunity.

The small, light, low-power, hermetically sealed SDC500 IMU provides industry-standard serial communication, configurable communications protocols, Time of Validity (TOV) sync, continuous Built-in Test (BIT), electromagnetic interference (EMI) protection, long MTBF and flexible input power compatibility making the SDC500 IMU easy to use in a wide range of challenging applications and operating environments.
