TDK Corporation (TSE:6762) expands the SmartIndustrial™ line of rugged and accurate motion sensors and announces the availability of InvenSense IIM-46234 and IIM-46230 new high-performance fault-tolerant inertial measurement units (IMU) aimed at navigation applications that require accurate, stable, and best-in-class in-class bias instability at an affordable price. IIM-46234 and IIM-46230 are modules containing multiple 6-axis sensors, each of which can measure three dimensions of linear acceleration and three dimensions of rotational speed. The calibration of these devices over the full temperature range (-40ºC to 85ºC) guarantees the best performance which is not typical for standard IMUs, which often show degrading performance as the temperature rises or falls. It also provides stable measurements at all temperatures to minimize position and angle errors for navigation applications. The modules also contain a microcontroller that provides multiple options for communication and sensor fusion.
Since these products provide accurate measurements even in harsh environments with high vibrations and large temperature fluctuations, this product family is well suited for a variety of navigation applications, including high performance real-time kinematic positioning (RTK) and GNSS/INS units, precision farming, construction equipment and industrial robots. An example application is an industrial autonomous vehicle or drone that requires best-in-class dead reckoning performance in the event of GPS signal loss.
“These types of high-end IMU modules were prohibitively expensive in the past. We now offer a solution that combines performance and affordability for customers developing navigation systems for drones, industrial autonomous vehicles and navigation systems,” said Camilo Delgado, Director of Product Marketing & Industrial Motion Sensor Business.
This new product family also integrates TDK’s unique SensorFT™ fault tolerance feature, which combines the multi-IMU hardware design with TDK’s proprietary fault detection and recovery software to provide built-in redundancy and early warning capabilities. A system containing IIM-4623X sensors can provide customers with advanced alerts, enabling preventive maintenance to avoid operational disruptions.
Products IIM-46234 and IIM-46230 are available from most global distribution partners. Product demonstrations are available at our main booth #B3.560 at Electronica in Munich, Germany.
