4-Position IDC Receptacle for Discrete Wire Harnesses
The TE Connectivity DuoPlug 3-284865-4 is a 4-position receptacle designed for mass-termination of discrete wire harnesses. It uses insulation displacement contacts (IDC) to terminate 22-24 AWG wire without stripping or crimping, saving assembly time on repetitive cable builds. The 0.098" (2.50mm) pitch matches the standard DuoPlug header footprint, keeping the board layout compact for a 4-circuit interconnect.
IDC Termination and Wire Range
IDC termination pierces the insulation of 22-24 AWG discrete wire as the contact is pressed into the housing slot — no wire prep beyond cutting to length. This makes the 3-284865-4 a repeatable option for harness builders who need consistent termination across a production run. The single-row 4-position layout keeps the connector narrow, fitting into a cable bundle without adding bulk.
Mating and Mounting
The free hanging (in-line) mounting means the receptacle floats in the harness rather than locking to a panel, which simplifies routing in applications where the cable needs to flex or reach a distant board. The right-angle wire exit keeps the cable profile low against the board surface.
