Housing Fit and Sealing for Harness Assembly
The housing is sealed, which means it keeps moisture and contaminants out of the terminal cavity — a requirement for under-hood automotive, outdoor equipment, or washdown-area harnesses where an unsealed connector would corrode over time. The 4.20mm pitch and 0.165" row spacing give enough room for 14-20 AWG power wiring without crowding the terminals.
Panel Mount and Locking in Vibration Environments
This housing mounts with a snap-in fit into a panel cutout, no screws or brackets needed — the integral latch grabs the panel thickness and holds the connector in place during mating and unmating. In a vehicle or machinery harness, that lock is what keeps the connection from walking loose over time.
