Motorized Zoom for Automated Machine Vision

The LZG-63104-A uses motorized optical zoom adjustment, allowing machine vision systems to change magnification without requiring manual lens adjustment.

This is useful for automated inspection stations that need to inspect different product sizes, switch between positioning and detailed inspection, or use different optical magnifications during different inspection steps.

The controller, cable and electrical interface should be confirmed according to the final system configuration. For OEM or automated equipment integration, confirm the required control method before ordering.
