The 1-480702-1: It accepts male or female crimp contacts (sold separately) and secures the mate with a latch lock, making it a practical choice for vibration-prone environments like industrial control panels or automotive under-hood wiring.
Contacts are not included — the housing ships empty, so you must order the matching crimp terminals separately. The 4-position single-row layout keeps the harness narrow, which helps when routing through tight conduit or along a frame rail. The latch lock provides an audible click on full mate, giving the assembler positive feedback that the connection is secure before the harness leaves the bench.
