Shock: 100g@11ms, three axial directions (half-sine wave)
Supply voltage: DC5.0V±0.5V

Product Introduction

The GIM302 inertial measurement unit consists of a three-axis gyroscope, a three-axis accelerometer, a temperature detection module, and data processing circuitry. It can monitor the three-dimensional angular velocity, three-dimensional linear acceleration, and spatial attitude information of a moving object in real time. Through an RS422/RS485 digital interface, it outputs complete inertial parameters after multi-dimensional error correction (including temperature drift compensation, assembly deviation correction, and nonlinear characteristic calibration) according to a predetermined communication protocol. The device employs a differential gyroscope design architecture, significantly reducing interference from linear acceleration and mechanical vibration. It also features wide-range temperature compensation, ensuring stable operation in harsh industrial environments.
