20-pin right-angle header for MTA-100 harnesses
The 5-641216-0: This is a 20-position, single-row header from the MTA-100 series, built for board-to-cable/wire connections.
What the friction lock and gold plating mean for field service
The friction lock holds the header in the mating housing without a secondary latch — it's a positive detent that resists vibration loosening. For a technician rebuilding a harness, this means the header stays put and the contacts stay clean through several re-mates.
