The TE Connectivity 1123340-1 is a 35-position plug housing from the.025 series, built for multi-row wire-to-wire or wire-to-panel harness applications.
The 2.20 mm pitch is tight enough to pack 35 circuits into a compact panel footprint, but still leaves room for individual wire seals or a secondary TPA if the application demands it. The four-row layout means the housing is wider than a typical 2-row plug — check your panel cutout and mating receptacle width before committing. The locking ramp gives a tactile latch engagement; in a high-vibration harness you want that positive lock rather than a friction-only fit. And the 'contacts not included' note is the one that trips up a first-time buyer — the housing ships empty, so line up the correct TE crimp socket terminal (check the.025 series terminal family) before you start your build.
