Product Specifications

Technical details and manufacturing context for Autofocus actuator

Definition
An autofocus actuator is a critical component within the main camera module responsible for precisely moving lens elements to achieve sharp focus on subjects. It receives signals from the camera's autofocus system and translates them into mechanical movement, enabling rapid and accurate focusing in various photographic conditions.
Working Principle
The actuator typically uses piezoelectric, voice coil motor (VCM), or stepper motor technology to convert electrical signals into precise linear or rotational motion. When the camera's autofocus system detects defocus, it sends control signals to the actuator, which moves the lens elements to the optimal position for sharp focus.
Common Materials
Neodymium magnets, Copper coils, Piezoelectric ceramics, Stainless steel housing
