Mouser Electronics, Inc., the authorized global distributor with the newest semiconductors and electronic components, is now stocking PowerHap™ piezo actuators from TDK EPCOS. These new piezo actuators with integrated sensor functionality feature exceptional acceleration, force and response time performance to offer an outstanding quality of haptic feedback for human-machine interfaces (HMIs) in vehicles, smartphones and tablets, household appliances, ATMs and vending machines, game controllers, industrial equipment and medical devices.
TDK EPCOS PowerHap actuators, available from Mouser Electronics, are based on multilayer piezo plates with cost-effective copper inner electrodes, which allow designers to drive the actuators with relatively low operating voltages up to 120 V. Unlike conventional electromagnetic solutions, PowerHap actuators can excite the entire stimulation range between 1 Hz and 1000 Hz. As a result, the actuators have no significant frequency or amplitude limitations for customized haptic feedback. In this way, the actuator enables designers to develop custom high-definition haptic feedback profiles that users expect from cutting-edge HMIs.
The PowerHap actuators are available in three types, each in a RoHS-compatible ceramic body with titanium cymbals for displacement amplification. The 2.5G type achieves a displacement of up to 35 μm and can generate an acceleration of 2.5 g forces of up to 5N in a 9mm × 9 mm footprint. The 12.7 mm × 12.7 mm 7G type achieves a displacement of up to 100 μm and can generate an acceleration of 7 g forces of up to 5 N. The 15G type is a 26 mm × 26 mm devices that can achieve a displacement of more than 200 μm. and can generate an acceleration of 15 g forces of up to 20 N.
