What is the 5111448-4?
The TE Connectivity AMP-Latch 5111448-4 is a 20-position, 2-row IDC plug designed for mass-termination of 26-28 AWG ribbon cable. The housing is black, and the connector mounts to a panel rather than hanging free on the cable, which gives the harness a fixed anchor point inside the enclosure.
Key specs for the BOM line
The 0.100" pitch and 20 positions are the first check — this plug mates with standard 20-pin IDC headers and receptacles at the same pitch. The panel mount feature uses the integral feed-through slot (listed as a feature) to pass the ribbon cable through the panel, with the plug body secured on the far side.
No crimp tool per wire; a simple press tool or vice works for the full 20 positions in one stroke. The mating half is a standard 20-pin, 0.100" pitch header or receptacle with female socket contacts — the AMP-Latch series includes the 1-226733-4 receptacle (17 positions, free-hanging) as a sibling, but for a 20-circuit match, look for a 20-position receptacle in the same series. The plug is keyed by its housing shape, so orientation is enforced at mate.
