At this pitch, the housing accepts the series' pin and socket crimp terminals (male or female), which are rated for up to 9.5 A per circuit with the appropriate wire gauge. The dual-row arrangement with 0.163" (4.14 mm) row spacing means the 20 positions fit in a compact 2-by-10 grid — useful when routing a harness through a tight panel opening or conduit.
You must source the crimp terminals separately — TE offers both male and female contacts for this series, in tin or gold plating. The housing accepts the standard Mini-Universal MATE-N-LOK crimp terminals. Factor the terminal part numbers into your BOM from the start.
