Housing for a 4-Circuit Power Interconnect
The 770336-1: The natural polyamide (nylon) body carries a detent lock that holds the plug mated to the matching receptacle without additional hardware, making it a practical choice for harnesses that see moderate vibration in industrial or automotive underhood environments.
The 4-position count matches a four-circuit power or signal harness — confirm your BOM line count before committing. The detent lock provides a positive tactile snap during mating and resists un-mating from cable pull or vibration, though it is not a secondary latch; for high-vibration duty, consider a tie-wrap or clip over the mated pair.
You will need to source the matching Commercial.093" pin or socket crimp terminals (male or female, depending on your circuit direction) and install them with the appropriate crimp tool.
