Kionix developed its tri-axis accelerometer in 2004, followed by introduction of the first ‘thin' 0.7-mm tri-axis accelerometer in 2013: this offering of full-featured ‘ultra-thin' low-power accelerometers follows that line. The company positions the KX112 and KXCJB as suited primarily for mobile, PC/tablet and wearable applications, and adds that it will continue to expand the portfolio to include automotive and heavy-duty industrial applications.
The KX112 tri-axis accelerometer is the thinnest 2x2 accelerometer available, and has full 16-bits of resolution and excellent stability; it features built-in digital algorithms for detecting motion for power management, free fall for device protection or warranty monitoring, an orientation engine for portrait/landscape detection, and tap/double-tap for user interface functionality. It also incorporates Kionix'sFlexSet technology, allowing fine granularity for balancing power and performance. The KX112 has the largest FIFO/FILO buffer available on a mass-produced accelerometer. With 2048 bytes available, the rest of the system can sleep while the device i recording more data than any other accelerometer on the market, enabling superior power-savings and event context. See next page for feature list.
The KXCJB is the thinnest accelerometer available in any footprint, measuring just 3 x 3 x 0.45 mm thick. It supports the drive for thinner smartphones, tablets, PCs and hard disc drives as well as compact wearables such as activity monitors and smartwatches. The unique form-factor is half the thickness of most accelerometers on the market. This brings the ability to embed motion detection and motion sensing capabilities into a host of new devices such as badges, access cards, and payment/smart cards, while also opening up possibilities of maintaining low profiles when mounting on or in glass, plastic and other thin structures.
