Product Description
Industrial 3-Axis MEMS Accelerometer XDA205
Technical Overview
The XDA205 is an industrial-grade dual-axis MEMS accelerometer featuring digital output with selectable measurement ranges of ±2g/±3g. Engineered with low noise, minimal temperature drift, and exceptional long-term stability, this accelerometer is ideal for high-precision measurement systems. Housed in a ceramic package, the XDA205 ensures reliable operational stability.
Advanced MEMS Technology
The LKF-XDA205 is a high-precision, compact capacitive MEMS accelerometer designed for inertial applications. The device integrates a MEMS sensing element and an ASIC chip, where the sensing element's capacitance varies with external acceleration, and the ASIC converts this into digital output signals. This product features independent design with fully localized manufacturing processes including packaging and testing.
Quality and Reliability
LIOCREBIF maintains complete control over upstream and downstream processes and technologies to ensure superior product quality while reducing system costs. The company operates under ISO9001 and GJB quality management systems, implementing strict production processes to guarantee consistent performance reliability.
In inertial navigation systems, the embedded MEMS accelerometer measures object acceleration and, through associated electronic circuitry, converts this data into precise position, orientation, and velocity information for accurate navigation of moving objects.
