Torrance, Cal. – Nidec Copal’s new LD14 miniature linear vibration actuator uses a new voice coil technology to develop an acceleration output of 1G at 150Hz operated by square wave output. The actuator is a compact 0.552” (14mm) long by 0.433” (11mm) wide by 0.10” (2.5mm) high, with only 2V and 77mA needed to excite the LD14 actuator.
The miniature brushless actuator is able to adjust its vibrating force without changing the vibration frequency. This surface mount device (SMD) provides high acceleration, superior reliability, and quick signal response for a wide range of mobile communication and safety devices. New applications involve devices and machines that use touch or tactile (haptic) motion and are used in video game and computer controllers, touch pads, robots and medical instruments.
