It uses a 7.80mm pitch — wide enough to handle heavier wire gauges without crowding the terminal pockets. The glass-filled PA66 insulation handles the thermal cycling typical of underhood or industrial cabinet environments.
Contacts Not Included — The Common Procurement Trap
The terminal part number for the Grace Inertia series uses the tab-type contact. The housing accepts the standard Grace Inertia crimp terminals; verify the wire gauge range against the terminal datasheet before committing.
Yellow Keying and Latch Lock — Vibration-Proof Mating
The yellow housing colour is not cosmetic — it is a visual keying feature that distinguishes this 2-position plug from other circuit-count variants in the Grace Inertia family. On a harness assembly line, the colour tells the operator which receptacle it mates with before they engage the latch. The latch lock provides the mechanical retention; once the latch clicks, the connection holds against the vibration profile of automotive or industrial machinery. No secondary locking mechanism is required for most applications, though the series supports a terminal position assurance (TPA) device if the application demands it.
