30mm PCBMotor S-mount Focus kit with 4mm travel - free aperture of 19mm

1 piece Focus motor for S-mount lenses (M12) with 100  steps position sensor and  integrated High Resolution driver. The focus unit, with motor and driver  is mounted on a 62x42x25 mm (LxWxH) .


Utilizing the same high-resolution controller as our Twin Motor kit, application engineers and designers can take advantage of and experience our record-breaking 2.6 million steps per revolution as well as full holding torque in power-off mode and a host of other features.

The high-resolution controller is easily connected to a PC and powered by a RX/TX to  USB cable. It communicates through a simple protocol that allows its custom-made software to quickly and easily access and control the motor. The high-resolution driver has built-in frequency tracking to automatically adjust the output for optimum performance according to motor size, operation temperature and load.
