The 4.80 mm pitch spaces the contacts wide enough to handle moderate current without forcing a tight terminal layout — common in harness assemblies where routing density is secondary to reliable termination. The glass-filled PA46 housing handles the -40°C to 150°C range, which puts it in the same thermal class as underhood automotive or industrial cabinet environments.
You select the TE crimp terminal that matches your wire gauge and current requirement. For the SSC series, the typical terminal is a stamped-and-formed pin or socket rated for the 4.80 mm pitch spacing. The housing accepts either male or female contacts, so it can serve as the plug half in a mating pair.
How Wide on the Rail? — Pitch and Layout
At 0.189" (4.80 mm) pitch across 12 positions in two rows, the housing occupies roughly 1.1" along the mating axis. That pitch gives enough room for a robust terminal body and a positive latch without crowding adjacent circuits. The free-hanging mount means no board footprint to design — the harness builder crimps terminals, inserts them into the housing, and routes the assembly to the mating receptacle.
