DC Power Jack for Board-Level Power Delivery
The TE Connectivity 1-2129458-2 is a DC-IN series power jack, a shielded female receptacle designed to accept a matching DC plug for board-level power input. It carries 3 conductors across 5 contacts, with the extra contacts providing additional ground or sense connections typical in coaxial power jacks. The 10.7 A current rating at 25 VDC means this jack is sized for power supply feeds — think wall adapters, battery chargers, or embedded system power inputs — not signal-level duty. Gold plating on the contacts gives it the corrosion resistance and cycle life for repeated plug/unplug in field-serviceable equipment.
Right-Angle Through-Hole Mount
That geometry suits enclosures where the power inlet sits flush with the chassis wall. The solder terminals handle the mechanical strain of cable insertion better than an SMT part would — the through-hole anchors take the push force off the solder joints.
Shielding and Construction
The shielded body contains radiated emissions from the DC line, which matters when the power jack sits near sensitive analog or RF stages. Housing is black thermoplastic (UL94 V-0 implied by the series class), and the contacts are copper alloy with gold plating — the gold layer handles the mating cycles of a user-facing power port without galling or oxidation.
