PUIaudio Haptic Feedback Components | Datasheet Preview

PUI Audio offers haptic feedback components for medical, industrial, and security applications. PUI Audio’s 8 by 3 millimeter thick HD-EM0803-LW20-R series is an eccentric rotating mass vibration haptic motor. Originally designed for use in pagers or beepers, this device is great for use in wearables for haptic feedback. Two models in this series use small DC motors. A flywheel is mounted on a rotating shaft, producing smooth rotation and no vibration. To create a vibration, an eccentric rotating mass counterweight is added to the shaft to create an artificial imbalance. Part of this series uses linear resonant actuator technology, which is typically the size of a small coin. As the AC passes through the coil, a magnetic field exerts varying degrees of force causing the magnet to move up and down. The mechanical movement exerts a force on the spring, creating a sense of vibration.
