Product details

TE HPI 1.25mm Receptacle Housing — 4-Circuit, Free Hanging

For the contacts, you need TE female crimp sockets designed for the 1.25mm HPI contact system; the housing is keyed to accept only the correct terminal form factor. 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.

Frequently asked questions

What contacts fit the 440146-4 housing?

The 440146-4 accepts TE female socket crimp contacts designed for the HPI 1.25mm contact system. The contacts are not included with this housing — order the TE crimp terminals separately, matched to your wire gauge.

What is the mating plug housing for 440146-4?

The mating half is the TE HPI series plug housing (male pin side) with the same 1.25mm pitch and 4-position, single-row layout. The plug housing accepts male crimp terminals and locks into this receptacle.
