The free-hanging mount means the assembly floats in the harness, so no PCB footprint is required — just crimp, insert, and lock. ## 1.25mm Pitch — Why It Matters for the Harness The trade-off is that the small pitch limits the current per contact compared to wider-pitch siblings, but for signal-level loads and low-power distribution, it saves real estate. The single-row, 4-position layout is a straight match for a 4-circuit harness run.","metaTitle":"TE 440146-4 HPI Receptacle Housing, 4 Pos, 1.25mm","metaDescription":"TE 440146-4 HPI receptacle housing, 4 positions, 1.25mm pitch, natural thermoplastic, free hanging.
