Miniature high performance IMUs offer up to 6G
These IMU's include triple gyroscopes and a tri-axis accelerometer, for 3 or 6 degrees of freedom. The gyroscope provides high accuracy and stability, while the accelerometer offers a dynamic range of up to +/- 6G. It offers excellent angular rate measurement performance and stability. These devices are also equipped with industry-standard SPI and UART interfaces and consume 30mA when operating at 3.3V.
Epson's current available IMU, the M-G350, has earned high marks from customers for its small size, light weight, and outstanding accuracy and stability. With the addition of the M-G352 and M-G362 to the product lineup, Epson will be able to support an even broader range of applications.
The M-G352 and M-G362 are equipped with additional new features, including a higher output data rate, an external trigger input, and counter reset function, making it easy to synchronize measurements with other sensors or with a GPS module in a user's system. Epson plans to begin shipping samples of the M-G362 and M-G352 in August and October of 2013, respectively.
|Upcoming small IMU series
Seiko Epson recently announced that they successfully developed the world's smallest IMU. The new M-V340 measures 10 x 12 x 4 mm, weighs 1 gram, and consumes just 18 mA of current, typical. Epson will begin shipping samples of the M-V340 in December 2013.
