Munich, Germany A joint development effort between Seiko Epson Corp. and NGK Insulators, Ltd. has resulted in the development of the industry's smallest gyro-sensor, according to both companies. Measuring 5.0 x 3.2 x 1.3 mm, the new surface-mount gyro-sensor, designated the XV-3500CB, represents Epson's first product line expansion beyond the scope of its quartz crystal business.
The gyro-sensor provides exceptional stability thanks to the use of a monocrystalline quartz crystal for the newly developed gyro element, said the company. By leveraging Epson's original crystal microprocessor, low-power analog circuit, and packaging technologies, the joint development team was able to develop the small gyro sensor with built-in drive and detection circuits
Operating on 2.7 to 3.3 volts, the new gyro-sensor features sensitivity of 0.67 mV/degree/second and linearity of ±5% FS. The detection range is 100 degrees/second. Its sleep mode function achieves both low power consumption and a short start-up time.
This subminiature angular velocity sensor is designed for use in systems that correct camera vibrations. The sensor will enable compact digital cameras, camera phones, and other products to be equipped with a high-performance motion correction feature. Epson will exhibit the new device at electronica 2004, November 9-12. Epson's booth is located at Hall A3, stand 642.
Volume production is scheduled for December 2004.
