First accelerometer with built-In noise filtering function

ROHM Group company Kionix is making available accelerometers, KX132-1211 and KX134-1211, that are suitable for high accuracy, low power motion sensing applications in the industrial equipment and consumer wearable markets.

As factories have begun to save labour costs and increase efficiency, the concept of predictive maintenance for detecting abnormalities before equipment malfunctions has gained much broader acceptance. This has increased the need for machine health monitoring along using sensors to detect equipment conditions (i.e. motor vibration).

The KX134-1211 is a 3-axis accelerometer optimised for machine condition monitoring.

Advanced Data Path (ADP) technology allows noise filtering and sensor signal processing normally carried out by the MCU to be performed by the accelerometer. They contribute to reducing MCU load and power consumption together with improved application performance.

In addition, to meet industrial requirements, the sensing frequency and acceleration detection ranges have been increased to 8,500Hz and ±64g, respectively, while supporting operating temperatures up to 105°C. At the same time, the sensor itself consumes less than half the current (0.67µA in low power mode) compared to conventional products.

Additional features include Wake Up and Back to Sleep functions that contribute to lower power consumption, enabling sensing operation in battery-equipped wearable devices.
