The latch holder locks the terminal in place once crimped and inserted. ## Mating Half and Fit The 174921-1 mates with the Multi-Lock receptacle header, also 3.50mm pitch, 3 positions. Free-hanging (in-line) mounting means it sits in the harness, not on the board — the header side takes the PCB mount.","metaTitle":"TE 174921-1 Multi-Lock Plug Housing, 3 Pos, 3.50mm","metaDescription":"TE 174921-1 Multi-Lock 3-position plug housing, 3.50mm pitch, white PBT, latch holder.
