The Libec DC-F20 is a specialized, high-performance data connection cable engineered to link the Libec FD-1 Focus Demand controller directly to Canon 20-pin portable broadcast lenses. It serves as an essential electronic pass-through, giving studio and remote field operators smooth, granular manual control over a lens's internal focus servo motors.
Core Features & Practical Utility
-
Direct Focus Servo Interface: This cable features a high-density 20-pin Hirose-style push-pull male connector on the lens side and a dedicated 6-pin push-pull male connector on the focus demand side. It translates rotation inputs from the FD-1 wheel directly into precision focal adjustments without any signal dead zones.
-
Lossless Voltage Shielding: Built with internal multi-strand copper lines insulated by a robust outer jacket, the cable prevents electromagnetic interference (EMI) and radio frequency (RF) clean-signal degradation when routed alongside high-power studio camera cables or studio lighting arrays.
-
Balanced 39.3-Inch Operational Sweep: Measuring exactly 39.3 inches (1 meter) in length, the line offers enough slack to route neatly down the tripod's panning handle without getting taut or binding during steep vertical tilts or fast panoramic camera pans.

Operational System Tips for the DC-F20:
💡 The Mechanical Push-Pull Lock: The Hirose-style multi-pin terminals on the DC-F20 feature an integrated sliding outer barrel lock. When breaking down a broadcast pedestal or field rig, never yank on the flexible rubber cable jacket itself to disconnect it from the Canon servo block. Grasp the knurled metal sleeve of the 20-pin plug directly and slide it straight backward to disengage the internal guide pins cleanly, protecting the delicate matching pin needles inside the lens housing from bending.
-
Isolating Rotation Direction: If an operator prefers the focus wheel to run clockwise for infinity rather than counter-clockwise, do not unplug or twist the DC-F20 cable. Simply toggle the physical Direction Reverse Switch located on the outer side chassis of the attached FD-1 focus demand housing to flip the electronic signaling layout instantly.
