4-Position Plug Housing at 4.20mm Pitch
The 4.20mm pitch gives enough room for 20-24 AWG power circuits without crowding the cavity wall, and the dual-row layout keeps the 4 positions in a compact 2x2 arrangement. The locking ramp on the plug body engages the matching receptacle latch for vibration-resistant retention — the TPA2 suffix means this series includes a terminal position assurance feature in the receptacle half that locks each crimp terminal in place before final assembly.
Crimp Termination — Contacts Ordered Separately
The crimp barrel gives a gas-tight connection on stranded wire when the correct tooling is used; the terminal's retention lance locks into the housing cavity and the TPA feature in the receptacle half provides secondary retention. For a complete mated pair, this plug mates with a Mini-Fit TPA2 receptacle housing of the same 4-circuit count and 4.20mm pitch — the matching receptacle order code from the same 172767 series.
The 4-position count at 4.20mm pitch is a common BOM line for power harnesses; the housing is bulk-packaged, so volume orders for harness builds are straightforward to quote.
