Barrington, Ill. Featuring ultra-fast response and high sensitivity, HDK America Inc.'s new micro-size, piezo-resistive three-axis acceleration sensor can detect minute amounts of dynamic acceleration in the X, Y and Z axis, and static acceleration such as tilt and gravitational simultaneously.
Based on a silicon substrate and high-precision micro-machining technology, the HAAM series provides a high sensitivity of 400 mV/G (Vcc=3V), and an acceleration rating of ±2G with a current consumption of 1 mA maximum. Other key characteristics include an output sensitivity of 400 mV/G (at 3 V of supply voltage, ratio metric output), an offset voltage of 1.5V ±0.075 V (ratio metric to supply voltage), and sensitivity of 20 mV/N with a linearity of ±3% FS. Operating life is a minimum of 1 million cycles. The operating temperature range is 0°C to 70°C. Shock resistance is more than 4,000 G.
Housed in a ceramic package with a footprint of 5.6 x 5.6 mm and a 2.0-mm height, these sensors are suitable for either consumer portable or business product applications. For example, if rapid acceleration, such as in a fall, is sensed by a HAMM sensor it communicates with the hard drive to "lock down" before impacting the floor.
Impacts can also be sensed to trigger an alarm. This alerts owners that their portable devices have been dropped, reducing the risk of loss.
Available for immediate delivery, prices start at $26 each in sample quantities.
