Universal Power Plug Housing, 4 Circuits
The 4-178842-1: It carries a 0.244" (6.20mm) pitch in a single row, with a natural polyamide (PA66) body and a latch lock that holds the mated pair together under vibration. The housing accepts female socket crimp terminals — contacts are ordered separately, so the BOM needs the matching TE crimp contact as a separate line item.
Pitch and Position Count
At 6.20 mm pitch, the 4-position housing gives each circuit enough spacing for moderate current without forcing a wide board footprint. The single-row layout keeps the harness narrow — useful where the connector runs along a panel edge or inside a tight cable tray.
Latch Lock and Temperature Range
The latch lock engages with an audible click, giving the field tech a positive confirmation that the plug is seated.
