Product overview
Closed-loop control for stable M12 autofocus movement
SDA03 is a closed-loop autofocus VCM actuator developed by Beijing MTS Electronics Co., Ltd. It combines a guided moving structure, Hall position feedback and I2C control interface in a compact 18.3 x 18.3 x 14.15 mm package.
The actuator is designed for M12 x P0.5 lens applications where a camera module needs controlled autofocus positioning, guided lens travel and support for compact lens assemblies up to 8 g.
Target applications
Built for practical imaging systems
Security Cameras
M12 camera modules requiring controlled focus adjustment and stable movement.
Web Cameras
Autofocus modules for high-quality video devices and conferencing camera systems.
Project Evaluation
Drone camera and other compact imaging projects can be reviewed case by case.
