The contact arrangement lists 3 conductors and 5 contacts — the extra contacts allow for a coaxial barrel tip (center pin), a sleeve, and a sense or switch contact. The jack does not contain an internal switch, so the sense contact is intended for a mating plug that shorts it to the sleeve to signal 'plug present'. ## What the Contact Plating and Shielding Mean for Your Build Gold plating on the mating surfaces (contact material - plating: Gold) handles repeated plug/unplug cycles without the oxidation that tin contacts develop over time. For a power jack that sees daily connection and disconnection — test equipment, field instruments, portable chargers — gold preserves low contact resistance through the service life. This keeps switching noise from the downstream DC-DC converter from radiating out the power port, and prevents external RF from riding the DC line into the device. Through-hole right-angle mounting (Mounting Type: Through Hole, Right Angle) gives the jack mechanical strength against the insertion force of a barrel plug — a surface-mount jack would tear pads off after a few cycles. Termination is solder (Termination: Solder) — no crimp or press-fit option. The through-hole pins are designed for wave or hand soldering. The housing is black thermoplastic (Housing Material: Thermoplastic), UL-rated but the specific grade is not listed; the insulation color matches the body.","metaTitle":"TE 1-2129458-1 DC Power Jack, 10.7 A, 25 VDC","metaDescription":"TE Connectivity 1-2129458-1 DC power jack, female, shielded, through-hole right-angle solder termination. 10.7 A, 25 VDC, gold-plated contacts.","metaKeywords":null},"attributes":{"series":"DC-IN","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Wire-to-Board Connectors"],"specifications":{"Mfr":"TE Connectivity AMP Connectors","Gender":"Female","Series":"DC-IN","Package":"Tape & Reel (TR) Cut Tape (CT)","Features":"-","Includes":"-","Shielding":"Shielded","Body Color":"Black","Termination":"Solder","Thread Size":"-","Body Material":"-","Mounting Type":"Through Hole, Right Angle","Connector Type":"Jack","Product Status":"Active","Actual Diameter":"-","Voltage - Rated":"25VDC","lifecycle_stage":"unknown","Contact Material":"Copper Alloy","Housing Material":"Thermoplastic","Insulation Color":"Black","Mounting Feature":"-","Ingress Protection":"-","Internal Switch(s)":"Does Not Contain Switch","Base Product Number":"2129458","Mating Length/Depth":"-","Current Rating (Amps)":"10.7 A","Operating Temperature":"-","Contact Material - Plating":"Gold","Material Flammability Rating":"-","Number of Positions/Contacts":"3 Conductors, 5 Contacts","Industry Recognized Mating Diameter":"-"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.0500","priceTiers":[{"qty":1,"price":"$4.05000","currency":"USD"},{"qty":10,"price":"$3.60700","currency":"USD"},{"qty":25,"price":"$3.58880","currency":"USD"},{"qty":50,"price":"$3.55180","currency":"USD"},{"qty":100,"price":"$3.20210","currency":"USD"},{"qty":250,"price":"$3.18372","currency":"USD"},{"qty":500,"price":"$2.94450","currency":"USD"},{"qty":1000,"price":"$2.63164","currency":"USD"},{"qty":2500,"price":"$2.42921","currency":"USD"},{"qty":9000,"price":"$1.90166","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icsourcedirect.com/845dc8112a515e4f119f821adad59574.pdf","sourceUrl":null,"alternativesUrl":"https://icsourcedirect.com/api/mcp/products/1-2129458-1/alternatives.json"},"ai":{"faq":[{"question":"What is the pinout of 1-2129458-1?","answer":"The 1-2129458-1 has 3 conductors and 5 contacts. The center pin carries the positive DC voltage, the outer sleeve is ground, and the additional contacts provide a sense or switch line — but the jack itself does not contain an internal switch, so the sense function depends on the mating plug.
