4-Circuit Economy Power Plug Housing — 3.96mm Pitch, Contacts Sold Separately
The 3.96mm (0.156") pitch is the standard Economy Power spacing — wide enough to route 18-22 AWG wire comfortably in the crimp barrel without crowding the adjacent cavity. The 4-position count matches a 4-circuit BOM line; the housing is keyed by the latch-lock ramp orientation, so verify the mating header's latch window aligns before committing the assembly.
Mating Half and Termination — What It Connects To
The latch lock snaps over the header's locking ramp for audible positive retention. Termination is crimp-style: the user inserts the appropriate Economy Power female socket contact (sold separately, typically 0.5-2.0mm² / 20-16 AWG range) into the PA66 cavity until the contact lance locks. The natural colour housing has no keying colour — orientation is set by the latch position.
