Multi-Lock 5-Position Receptacle Housing — What It Is
It uses a 4.50 mm pitch and a latch-lock fastening system for a positive, audible mate in free-hanging (in-line) harness applications.
The listing note is clear: contacts are not included. This is a common trip-up on the Multi-Lock series — the housing and the crimp terminals are ordered as separate line items.
The latch lock provides vibration-resistant retention — you will hear it click when the halves are fully seated. The single-row, 5-position layout at 4.50 mm pitch gives you enough room between contacts for hand crimping or semi-automatic tooling without crowding.
The closest functional peer in the Multi-Lock family is the 1-1376477-6 — a 6-position plug housing at 2.50 mm pitch, also free-hanging with a latch lock and crimp termination, but in a red glass-filled nylon housing. The 347477-1 gives you a wider 4.50 mm pitch (better creepage for higher-voltage harnesses) and a 5-position count against the 6-position count of the sibling. Both are active, so the choice comes down to the position count and pitch your BOM requires.
