Product Description
The MS2A-H is a dynamic tri-axis accelerometer and tri-axis gyroscope inertial measurement unit with RS232/CAN/ CANFD communication interfaces. The IMU sensor integrates a high-precision MEMS 6DoF inertial component into a highly protective housing. Calibrated through DAISCH's factory calibration process, it delivers highly consistent performance even in extreme operating environments, making it particularly suitable for various dynamic control and navigation applications.
MS2A-H can measure the positive and negative tilt angles of X axis and Y axis, and the measurement accuracy can reach ±0.1°. It has the function of zero bias self-learning and time synchronization. With IP67 rated sealed housing and automotive-grade 8pin connector, it easily pairs with a high-reliability Molex cable to provide a robust motion sensing solution for autonomous driving and construction machinery applications.
