34-Position Superseal Plug Housing for Harsh-Environment Harnesses
The TE Superseal 3-1437290-9 is a 34-position plug housing designed for wire-to-wire interconnects in demanding environments. It uses a 4-row, 3.00 mm pitch layout — the 34 circuits match a dense signal harness or a mixed power/signal bundle, and the wide pitch keeps creepage distances adequate for the automotive-grade insulation.
The thermoplastic polyester insulation material holds its dimensional stability across that span — no cold-crack at -40°C, no creep at 125°C. For a harness builder, that range means the housing can be specified into an assembly that sees both arctic startup and under-hood heat soak without derating the connector system.
