It accepts crimp-terminated female socket contacts and mates with the corresponding AMPMODU Mod IV male header pins.
Why the 44 Positions and 0.100" Pitch Matter for Your BOM
The 44 circuits at 0.100" pitch mean this housing occupies about 4.4 inches of board edge or harness real estate — a dense but serviceable layout for signal-level interconnects. The dual-row arrangement keeps the connector width manageable while packing enough circuits for a parallel data bus or a multi-conductor sensor harness. Because the housing is free-hanging, it does not require a PCB footprint; the crimp terminals are inserted into the housing and the assembly is wired directly into the harness. The polarizing key is a practical field-service feature — in a cabinet with several identical-looking Mod IV connectors, the key ensures only the matching header engages, which saves troubleshooting time during rework or replacement.
You must order the matching AMPMODU Mod IV crimp female socket terminals separately. This two-step process is standard for field-terminated harnesses where the wire length and routing are determined on the assembly bench, not at the PCB.
