The ARM-based KX23H sensor hub is an innovative new product in the accelerometer sector. It combines a high-performance, low-power 3-axis acceleration sensor with a 32-bit ARM CortexTM M0 microcontroller in a small 3x3x30.9mm housing. An extensive library of movement processing software provides the user with such functions as step counter and calorie counter, movement monitoring as well as the possibility of distinguishing between different types of movements such as walking, running, car or train. Furthermore, there are additional functions for tap/double-tap, screen rotation, tipping and many more. Other acceleration sensors from Kionix are available in various housing sizes from 2x2x0.9mm to 5x5x1.2mm.
The current highlight in the 9-axis combination sensors segment is the first magnetic gyro solution. Here, a gyro is emulated on the basis of the magnetic field and acceleration sensors. The KMX61G accelerometer/magnetometer solution from Kionix offers the highest precision thanks to highly developed sensor fusion software and automatic calibration algorithms. Optimised especially for mobile applications, the KMX61G in the 3x3x0.9mm housing requires only 450µA current and thereby significantly less than the presently available hardware gyroscope for the end customer market. Test specimens are available right now from Rutronik.
Kionix ranks amongst the leading manufacturers of MEMS sensor solutions with special expertise for embedded algorithms such as tap recognition, screen rotation, gesture recognition and activity monitoring. Kionix product innovations include the first miniature-sized 3-axis acceleration sensor or the first acceleration sensor with integrated algorithm for free-fall recognition. “With Kionix products, we can now offer our customers an even more extensive range of sensors for completely different applications,” explains Martin Grimmer, Senior Marketing Manager Analog & Sensors at Rutronik. “They are especially interesting because they are really trailblazing solutions which combine high performance with low power.” With inhouse mass production, Kionix is using the proprietary MEMS technology of plasma microprocessing. In this way, Kionix can offer powerful MEMS products at an attractive price.
Since 2009, Kionix is a subsidiary of ROHM Semiconductor. ROHM is already a Rutronik sales partner since 1999. As a distributor, Rutronik sells the entire ROHM product range throughout Europe, including integrated switches (ICs), diodes, transistors, LEDs, resistors, tantal condensers and displays.
