The TE 1-440146-1 is an 11-circuit receptacle housing from the High Performance Interconnect (HPI) series, built for free-hanging wire-to-board or wire-to-wire harness applications. It uses a 0.049" (1.25mm) pitch — tight enough for dense signal routing but still workable with small-gauge crimp terminals.
Wiring It Up — Contacts and Termination
The 1-440146-1 uses crimp-style female socket contacts. The housing itself has no terminals — you buy the matching crimp contacts separately (TE part family 440146). The 1.25mm pitch means the wire gauge will be on the smaller side, typically 26-30 AWG for signal-level current. The single-row layout makes it straightforward to load by hand or with a simple hand-crimp tool.
