TDK Corporation extends the SmartIndustrial line of robust and accurate motion sensors and announces the availability of InvenSense IIM-46234 and IIM-46230 new fault-tolerant inertial measurement units (IMU) targeted at navigation applications that require accurate, stable, and bias instability at an affordable price.
IIM-46234 and IIM-46230 are modules that include multiple 6-axis sensors, each of which can measure three dimensions of linear acceleration and three dimensions of rotational rate. The calibration of these devices over the full temperature range (-40ºC to 85ºC), guarantees performance not typical in standard IMUs, which often have deteriorating performance as temperatures increase or decrease. It also provides stable measurements across all temperatures to minimise errors in position and angle for navigation applications. The modules also include a microcontroller that provides multiple options for communication and sensor fusion.
As these products offer precise measurements, even in harsh environments with high vibrations and wide temperature variations, this product family is well-suited for a variety of navigation applications, including high-end real-time kinematic positioning (RTK) and GNSS/INS units, precision agriculture, construction machinery, and industrial robots. An example application is an industrial autonomous vehicle or drone that requires dead reckoning performance in case of GPS signal loss.
“These types of high-end IMU modules have been cost-prohibitive in the past. We now provide a solution that combines performance and affordability for customers developing navigation systems for drones, industrial autonomous vehicles, and navigation units,” says Camilo Delgado, director of product marketing & industrial motion sensor business.
This product family also integrates TDK’s SensorFT feature for fault tolerance, which combines the multi-IMU hardware design with TDK’s proprietary fault detection and recovery software, to deliver built-in redundancy and early warning capabilities. A system that includes IIM-4623X sensors could provide customers with advanced warnings, enabling preventative maintenance to avoid operational disruption.
The IIM-46234 and IIM-46230 products are available at most global distribution partners. Product demonstrations are available at our main booth #B3.560 at Electronica in Munich, Germany.
