Multi-Lock Plug Housing for 4-Circuit Harnesses
The 174922-1: It uses a 3.50mm pitch, giving enough spacing for moderate current per circuit without blowing up the connector width. The housing is white PBT with a latch holder that locks the mated pair together — the latch gives positive retention in applications that see vibration or incidental tugging on the harness.
For the Multi-Lock series, the typical compatible contact is a 3.50mm-pitch female terminal (TE part numbers like 174919-1 or similar in the series). The housing accepts the crimped terminal, which is then inserted and retained by the latch holder. Always confirm the exact wire gauge range and terminal part number against the TE application drawing before ordering in volume.
The 174922-1 plug mates with the matching Multi-Lock header or receptacle that uses the same 3.50mm pitch and latch holder system. A common mating half is the TE 174919-1 (or its variants), which is the corresponding receptacle housing. Because the series uses a standardized pitch and latch geometry, any Multi-Lock header with the same position count and latch holder will mate — but always verify the specific header part number against your assembly drawing.
