Aceinna has launched a new high-accuracy inertial measurement unit (IMU), the IMU383ZA. The sensor integrates triple-redundant, 3-axis micro-electromechanical system (MEMS) accelerometer and gyroscope sensors.

The IMU383ZA is an improved, pin-compatible version of Aceinna’s IMU381ZA. It offers high performance (1.3 deg/hr, 0.08 deg/root-hr) and a triple-redundant sensor architecture for ultra-high reliability.

The miniature module is factory-calibrated over the -40° C to +85° C industrial temperature range to provide consistent performance through extreme operating environments for a wide variety of applications.

Applications include automotive advanced driver-assistance systems (ADAS), autonomous systems, drones, robotics, agricultural, construction and other industrial machines.

The IMU383ZA provides a standard SPI bus for cost-effective board-to-board communications. Other features include advanced synchronization and a bootloader for field upgradeability.

Measuring 24 x 37 x 9.5 millimeters, the IMU383ZA integrates a triple-redundant architecture that — combined with the small, low-cost packaging — meet the challenging performance, reliability and cost requirements of the automotive market including the areas of autonomous vehicles, self-driving taxis/delivery vehicles, ADAS systems, electronic stability control and lane-keep assist applications.

The triple-redundant sensor architecture consists of three independent, 3-axis accelerometer and 3-axis gyros for excellent accuracy and reliability. By embedding a triple-redundant sensor array, the IMU383ZA uses Aceinna’s proprietary voting scheme to utilize only valid sensor data. Any defective sensor output or errant dataset will be ignored or de-rated in importance.
