Housing for a 26-Position Wire-to-Board Harness
The 104483-4: It is designed for free-hanging, in-line crimp termination — you build the wire harness first, then mate it to a matching AMPMODU header on the PCB.
You order the AMPMODU crimp socket terminals separately (TE part numbers AMPMODU IV or similar, depending on wire gauge). It mates with any standard AMPMODU 0.100" pitch, dual-row, shrouded or unshrouded header that has 26 positions. The polarizing key aligns with a matching slot on the header, so verify the header has the keyway if you need that mis-mate protection.
