Fujinon EPD-41A-D02 Digital Focus Position Demand Unit

The EPD-41A-D02 is Fujinon's digital focus position demand unit, the handle-mounted control that gives an operator remote servo focus on a Premier, Select or Broadcast series lens. It connects to the lens's focus servo connector with a 12-pin cable rather than a mechanical linkage, so focus tracking stays smooth and repeatable through a long shot.

The unit carries indicator lights, two auxiliary buttons, and a torque adjustment for feel, plus a DIP switch bank that sets focus direction, focus mode, and auxiliary functions including an OIS alternate mode and preset zoom support. It mounts to a lens handle with a Fujinon MCA-37 clamp and is the focus half of the SS-15D full-servo control kit.
