LEMO 3K.93C SMPTE 304M HDTV camera connector

LEMO 3K.93C is a broadcast-camera hybrid connector family associated by the manufacturer with the SMPTE 304M HDTV camera interface.

Also called LEMO 3K.93C SMPTE 304M camera connector SMPTE fiber camera connector HDTV camera hybrid connector

A standard designation is not enough to approve a cable assembly or powered camera link; exact connector, cable, cleaning, power and equipment requirements still apply.

Look for

Confirm the 3K.93C family and SMPTE camera-link documentation rather than treating any round hybrid fiber connector as equivalent.

Use the source-backed form or position count only for identification. Resolve ratings, protocol, direction, wiring, cable construction and exact device support from the relevant equipment and component documentation.

Before you connect

What to check

  1. Identify the exact connector family and variant from the equipment or cable documentation.
  2. Keep shape, contact count, protocol, electrical rating and device support as separate facts.
  3. Do not force, rewire or adapt a connector from this recognition record; resolve the remaining requirements first.

Pins & wiring

Pinout

Choose the exact wiring. Pin numbers follow its stated view; a schematic does not establish physical positions. Check your exact device before wiring.

What the status labels mean
Confirmed
Recorded research passes agree within this variant; this is not independent human review or hardware validation.
Single source
Only one underlying document, or one pass, supports this assignment.
Device-specific
Supported for the named equipment or wiring only. Check your device’s manual.
Unverified
Missing or conflicting evidence. Do not wire from this row.
Not connected
The source explicitly says NC, no contact or no pin for this wiring.

  • The insulator drawings show six contacts of three visual types plus the 'N' marking but no legend; mapping drawn shapes to fibre/power/signal was not done to avoid guessing.
