The 1.80 mm pitch saves board real estate compared to the standard 2.54 mm header, while the sealed construction keeps moisture and debris out of the connection — a common requirement for under-hood or exposed sensor harnesses.
At 1.80 mm pitch, this housing mates with the matching Mini50 header on a tight board layout — the narrow spacing lets you run more circuits per inch than a standard 0.100" header. The sealed rating means the connector pair keeps water spray and dust out when mated, so it's suited for door modules, mirror harnesses, and engine-bay sensor connections where an unsealed connector would corrode over time.
The single-row, 2-position layout keeps the harness narrow and easy to route. Mates with the corresponding Mini50 header (male pins) at the same 1.80 mm pitch.
