Fine-Pitch Discrete-Wire Plug for Tight Harness Routing
Its 0.031" (0.80mm) pitch packs ten circuits into a narrow footprint — noticeably tighter than the 2.54 mm pitch common on general-purpose headers, so the mating receptacle and the board footprint must match that fine pitch exactly. Gold contact finish on all terminals means this plug is specified for applications where corrosion resistance and repeated mating cycles matter — think portable equipment, instrumentation, or any environment where the connector sees field service. Termination is solder to discrete wires, not crimp — the installer strips, tins, and solders each conductor into the outer shroud contact. That makes this plug a fit for low-to-medium volume builds or field repairs where a crimp tool and die set for 0.80 mm pitch contacts isn't justified. The free-hanging (in-line) mount means it floats in the harness; there are no panel-mount ears or board-lock pegs, so the cable bundle takes the strain, not a fixed chassis point. The (50) suffix in the order code indicates a specific packaging or plating variant within the 3240 base product number — functionally identical to the other (50) suffix parts in the series, but the exact suffix must match the BOM line to avoid a wire-prep mismatch.
Mating Connector and Termination Checklist
This plug mates with a Hirose 3200 series receptacle that shares the same 0.80 mm pitch and 10-position count. Termination on this plug is solder to discrete wires — confirm the wire gauge fits the solder cup before committing the build. The black housing is keyed by the shroud profile; no polarisation pin is listed, so the orientation is fixed by the housing shape.
