Voice Coil Motor M12 Lens Mount with 23.5mm hole spacing

The CLA321-VCM is an affordable voice-coil auto-focus motor for M12 Lenses. It is rated for lenses up to 7g. This VCM has a full stroke of 400um. Unfortunately, we do not currently provide SW/FW drivers. We recommend the Dongwoon DW9714 or Texas Instruments DRV201 as a driver. There are many other VCM alternatives with different size; please contact us for more details. Please also see our alternative ultrasonic M12 lens focus motor which includes a driver and USB adapter board.
