By developing and adopting a voice-coil method, our auto-focus linear motors are designed to drive the lens unit in the cameras of mobile phone handsets.

A floating mechanism and power connection adopting a newly-developed flat spring made it possible to attain a very quick response time for lens focus, and to maintain high levels of stability and reliability.

There is no shaft required to hold the lens in the mechanism so, as there is no movement of axes when the lens moves, it can attain a high level of accuracy.

These motors are the ideal product for mobile phone handsets with high density and high quality display monitors by providing a very accurate focus with the subject target.
