Housing for a Power-Duty Harness
The TE Connectivity 1-178288-7 is an 8-position receptacle housing from the Dynamic D-3100 series, built for wire-to-board or wire-to-wire power interconnects in industrial and automotive applications. The 3.81mm pitch gives enough creepage for moderate-voltage power circuits without forcing an oversized connector footprint. This is a single-row, free-hanging (in-line) housing that accepts crimp female socket terminals — the contacts are ordered separately. A polarizing key prevents mis-mating with the wrong header.
What Fits and What Doesn't
This housing mates with the matching Dynamic D-3100 series pin header. The crimp terminals are sourced separately — the 1-178288-7 ships as a bare housing with no contacts included. For a complete harness, order the appropriate Dynamic D-3100 female crimp socket (typically 20-16 AWG range, depending on current requirements) and insert it into the cavity until the retention lance locks.
