Sourcing the Contacts and Mating Half
Because the 1-1447232-7 is a plug housing with no contacts included, the immediate question is what terminal to load and what receptacle it mates with. The Superseal series uses a common crimp socket terminal — the TE 828904-1 (for 20-17 AWG) or 828905-1 (for 17-13 AWG) are the usual fit, though the exact contact depends on your wire gauge. The mating half is the corresponding 26-position Superseal receptacle housing (TE 1-1447232-5 or similar 26-position female housing). The 4-row keying means you need the matching 4-row receptacle — the latch lock clicks home and the seal ring (on the receptacle side) compresses for the IP rating the series is known for.
