It carries 10 circuits across 2 rows on a 0.118\" (3.00mm) pitch, matching the standard Micro-Fit 3.0 footprint. Use it to extend a harness, create a service loop, or break a wire run at a panel junction where you need a disconnect point. ## Mounting and Fit — Free-Hanging Only This adapter is free-hanging (in-line) only — no board-mount lugs, no panel flange. The two plug bodies snap together as one unit, and each end accepts a standard Micro-Fit 3.0 receptacle housing. The 3.00mm pitch gives enough room for 20-24 AWG wire with the matching crimp terminals.","metaTitle":"Molex 2451321099 Micro-Fit 3.0 Adapter, 10-Pos, 3mm","metaDescription":"Molex 2451321099 Micro-Fit 3.0 adapter, plug/plug, 10 positions, 3.00mm pitch.
