The 350720-1: It is a free-hanging (in-line) connector with a latch-lock fastening system that provides a positive, vibration-resistant mate. The housing is molded from natural polyamide (nylon) and accepts either male or female crimp contacts — but the contacts themselves are not included and must be ordered separately. This series is a workhorse for internal power and signal wiring in appliances, industrial controls, and automotive harnesses where a reliable, field-repairable connection is needed.
What You Need to Order Alongside It
Because the 350720-1 ships as an empty housing, you will need to source the matching crimp terminals separately. The Universal MATE-N-LOK series accepts both male and female contacts, so the terminal type depends on whether this plug mates with a header or a receptacle. The contacts are crimp-terminated to the wire before insertion, and the latch lock holds the mated pair together — no secondary locking device is required.
