The 4.20mm pitch keeps the contact spacing wide enough for 20-24 AWG power circuits without crowding the harness.
Mounting and Termination — Snap-In and Crimp
This housing mounts to the panel with a snap-in fit — no hardware, no tools, just push it through the cutout until the retention barbs seat.
Glow Wire and Temperature Range
This housing is glow wire compliant.
The sibling 2004882005 is the same Mini-Fit Sigma 4.20mm pitch plug housing with identical features — glow wire compliant, locking ramp, snap-in panel mount — but in a 5-position version. The 2004882004 is the 4-position variant. The decision is purely circuit count: match the housing position count to the number of power circuits your harness carries.
