It carries 2 conductors across 3 contacts — the extra contact typically serves as a coaxial center pin or a sense/shield return, common in barrel-type DC power jacks. ## Termination and Mounting — Solder Eyelet, Free-Hanging Termination is via solder eyelet(s) — a field-service-friendly method that accepts tinned or pre-tinned wire ends without a crimp tool. The free-hanging (in-line) mount means this plug sits at the end of a cable assembly, not on a panel or PCB. Housing is yellow thermoplastic — the color is a visual cue for DC power, reducing the chance of mismating with AC or signal connectors. Contacts are copper alloy with gold plating, giving good corrosion resistance and stable contact resistance over repeated mate cycles. The connector does not contain an internal switch — it is a straight-through power path with no sense-circuit interruption. ROHS3 compliant.","metaTitle":"TE 1-2129334-1 DC-IN Power Plug, 25VDC, 10.7A, Solder Eyelet","metaDescription":"TE Connectivity 1-2129334-1 DC-IN series power plug, male, 2 conductors/3 contacts, rated 25VDC at 10.7A.
