Panel-mount snap-in — no tools needed
The 1-350780-9: The housing snaps into a rectangular panel cutout and locks in place with integral retaining tines. No mounting hardware, no screws — push it through from the front until the tines click past the panel edge. The single-row layout keeps the footprint narrow, so you can gang several housings side by side on a control panel or junction box wall.
You pick the crimp terminal based on your wire gauge and current needs: the series accepts both male and female contacts, so one housing can serve as either the receptacle or the plug side depending on which terminal you load. The crimp termination means you need a hand crimper or a semi-auto press for the production line, but it also means you can field-repair a damaged contact without replacing the whole housing — just extract the terminal and crimp a new one.
