The 13 cavities are laid out across 3 rows with a 5.60 mm row spacing, which is wider than the 3.30 mm spacing on the 2-row 1-2333134-5 sibling from the same family. That extra gap between rows gives room for larger-diameter wire or a sealing grommet if the application calls for it. The latch lock then holds the mated pair together — no secondary locking mechanism required for most applications, though the housing accepts a TPA (terminal position assurance) insert if the spec demands it.
Row Spacing, Contact Type, and What Trips People Up
The contact type is male pin, which means this receptacle housing accepts the male terminals — the pins that insert into a female socket on the mating half. That's the opposite of what many technicians expect from a 'receptacle' label. Grab the 344260-1 when your harness terminates in male pins that plug into a female header or device-side connector. If your circuit calls for female sockets on the free-hanging side, you need the matching plug housing from the EconoSeal III 070 series.
