The 5.00mm pitch gives enough spacing for a clean crimp termination on each circuit without crowding the wire seal area.
This housing ships with no contacts — the note is explicit: Contacts Not Included. The housing accepts a female socket contact terminated via crimp; the contact itself is not part of this order code.
The 8-1241983-2 is listed as Active — no obsolescence notice, no last-time-buy clock ticking. It is a current-production part from the Standard Timer line, which means the crimp terminals and mating headers are also still in the catalog.
The 5.00mm pitch is the key board-layout dimension — the mating header's pin spacing must match exactly. The single-row 2-position layout is straightforward: two circuits, one row, no alignment worries. The PA6 nylon housing is not glass-filled, so it is suited for general-purpose interior environments rather than high-temperature engine-bay locations.
