Sealed 4mm pitch header for harness routing
The 1-776230-1: This AMPSEAL header uses a 0.157" (4.00mm) pitch across 35 positions in 3 rows — the spacing is wide enough to keep routing clean in a sealed harness, and the 4-wall shrouding protects the male pins during mating. The locking ramp fastening and sealable design (mounting flange included) mean this header holds its mate under vibration and keeps moisture out — it's built for under-hood automotive or outdoor industrial cabinets where a standard header would corrode or walk loose.
