68-position Mini Delta Ribbon (MDR) connector

The 68-position Mini Delta Ribbon form increases contact density within the MDR family and can be confused with other compact legacy external connectors.

Also called MDR 68 Mini Delta Ribbon 68 68-position MDR half-pitch ribbon 68

A 68-contact MDR shell is not the same mechanical family as VHDCI merely because both can expose 68 contacts.

Look for

Confirm the MDR series and 68-contact variant from markings or component documentation; do not identify it from contact count alone.

The useful distinction

Recognize it. Then verify it.

The 68-position Mini Delta Ribbon form increases contact density within the MDR family and can be confused with other compact legacy external connectors. [C245A]

A boundary, not an omission to guess around.

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.

What is not established

This field note does not approve a connection, adapter, cable assembly, rewiring scheme or fabricated part. It intentionally omits unsupported pin assignments and mechanical tolerances.
