Housing for a 4-circuit power or signal interconnect
The 174929-1 is a 4-position receptacle housing from TE's Multi-Lock series, designed for wire-to-board applications where a separate crimp terminal is inserted into the cavity. The 3.50 mm pitch gives it a compact footprint while still allowing moderate current per circuit — typical for power distribution or signal lines in automotive and industrial equipment.
What contacts and mating half to order
The contact type is a tab, terminated by crimp, and the housing accepts the matching TE Multi-Lock tab contacts. For the mating half, look for the corresponding Multi-Lock header (plug) with 4 circuits on the same 3.50 mm pitch. The white PBT insulation material provides good dimensional stability and chemical resistance for the intended use.
