12-Circuit In-Line Plug Housing for Micro MATE-N-LOK
The TE Connectivity 1-1445049-2 is a 12-position plug housing from the Micro MATE-N-LOK series, built for free-hanging (in-line) crimp termination. It uses the standard 3.00 mm pitch that defines this series, and the single-row layout keeps the harness narrow — useful when routing through a tight conduit or along a panel edge.
Contacts and Crimp — What You Need to Order Separately
A critical note on this line: contacts are not included with the housing. The 1-1445049-2 is a bare plug shell; you must source the matching male pin crimp terminals separately. For the Micro MATE-N-LOK system, TE offers several pin contact options — typically in 20-24 AWG range with either tin or gold plating depending on the mating cycle and corrosion requirements. The crimp termination means you need the correct applicator and die set to hit the target crimp height; sectioning a sample pull-test is the only way to confirm the wire strands are fully captured and the crimp barrel hasn't bottomed out on the insulation. Wrong die, wrong crimp — and you'll see it in the pull-force reading before the harness ships.
Mating Half and System Compatibility
This plug housing mates with the matching Micro MATE-N-LOK receptacle headers — the ones with the same 3.00 mm pitch and locking ramp interface. The male pin contacts in this housing engage with female socket contacts in the receptacle side. Because the series uses a standardized keying and ramp geometry, any Micro MATE-N-LOK receptacle header at the same pitch and position count will mate, provided the header is the receptacle type (female socket contacts). The 12-circuit count on this plug matches a 12-position receptacle header for a direct wire-to-board or wire-to-wire connection.
