12-Circuit HPI Receptacle Housing for 1.25 mm Pitch Harnesses
The TE Connectivity 1-440146-2 is a 12-position receptacle housing from the High Performance Interconnect (HPI) series, built for free-hanging (in-line) crimp termination at a 0.049" (1.25 mm) pitch. The natural thermoplastic body carries a single row of female socket cavities, each accepting a separately ordered crimp terminal. This pitch and row count suit compact wire-to-board or wire-to-wire harnesses where board space or bundle diameter is tight — think sensor arrays, LED lighting strips, or appliance control looms.
The female socket terminals for the 1.25 mm pitch HPI series are ordered under a different TE base number (440146 family).
The 1.25 mm pitch and single-row 12-position layout are the mating half match criteria; the header must share the same pitch, position count, and row configuration. There is no locking ramp or secondary latch on this housing, so the retention relies on the terminal-to-housing interference fit and the friction of the mated pair. For applications under vibration, a positive-lock version of the HPI series (with a locking ramp feature) would be the better choice — but that is a different order code.
