ACEINNA has announced high volume availability of the new ACEINNA IMU383ZA IMU sensor, which integrates triple-redundant, three-axis MEMS accelerometer and gyroscope sensors.

This miniature module is factory-calibrated over the -40 to +85°C industrial temperature range, to provide consistent performance through extreme operating environments for a wide variety of applications including automotive ADAS, autonomous systems, drones, robotics, agricultural, construction, and other industrial machines.

The IMU383ZA offers improved performance, in addition to a unique fault-tolerant sensor architecture for improved reliability. The IMU383ZA provides a standard SPI bus for cost-effective board-to-board communications. Other critical new features include advanced synchronisation and a bootloader for field upgradeability.

Measuring only 24x37x9.5mm, the ACEINNA 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, Lane Keep Assist applications, etc.

“The recently developed ACEINNA IMU383ZA is an improved, pin-compatible version of our popular IMU381ZA,” explained Michael Murphy, Executive VP at ACEINNA. “It offers high performance (1.3 deg/hr, 0.08 deg/root-hr), and a triple-redundant sensor architecture for ultra-high reliability. “

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