2.5mm 4 pole phone jack DW-PJ-D2066-A is a right-angle DIP/through-hole PCB socket designed for a Ø2.50 mm 4-pole plug. It features a six-terminal configuration, 0.5 A DC max / 12 V AC RMS rating, gold-flash-over-nickel copper-alloy terminals, UL 94V-0 high-temperature housing, 5,000-cycle durability, and RoHS-compliant construction.
Applications: Audio interfaces, wired headset connections, portable electronics, multimedia equipment, communication devices, control equipment, and compact PCB assemblies using 2.5 mm four-pole plugs. Comparable 2.5 mm four-pole audio jacks are also used in audio equipment and portable electronic devices.
Highlights: Ø2.50 mm 4-pole plug interface; A circuit configuration; six terminals; right-angle DIP/through-hole PCB mounting; 0.5 A DC maximum current; 12 V AC RMS voltage rating; ≤50 mΩ initial contact resistance; ≤100 mΩ after life test; ≥50 MΩ insulation resistance at 500 VDC; 500 VAC withstand voltage; ≤29.4 N insertion force; ≤2.94 N unmating force; 5,000 mating cycles; copper-alloy terminals; gold flash over nickel; black UL 94V-0 high-temperature housing; RoHS compliant.
2.5mm 4 pole phone jack DW-PJ-D2066-A is a right-angle DIP/through-hole PCB socket designed to mate with a Ø2.50 mm 4-pole plug. The Dragon Well drawing shows a six-terminal PCB layout and the A circuit configuration, with a compact horizontal-entry structure for board-mounted audio and signal interfaces.
The connector is rated at 0.5 A DC maximum and 12 V AC RMS. Initial contact resistance is specified at 50 mΩ maximum, increasing to 100 mΩ maximum after the life test. Insulation resistance is 50 MΩ minimum at 500 VDC, while dielectric withstand voltage is 500 VAC. Mechanical requirements include a maximum insertion force of 29.4 N, a maximum unmating force of 2.94 N, and durability of 5,000 mating cycles.
This 2.5mm 4 pole phone jack uses a black high-temperature housing rated UL 94V-0. Terminals 1 through 6 are manufactured from copper alloy with gold flash over nickel, with the drawing specifying a nickel underplate of 40 µin minimum. Terminal thickness is 0.20 mm for terminals 1, 2, 4, 5 and 6, while terminal 3 is 0.15 mm. The recommended PCB footprint and terminal numbering are defined directly in the drawing for consistent board integration.
The 2.5mm 4 pole phone jack is suitable for compact audio and communication interfaces, wired headset connections, portable electronics, multimedia devices, control equipment, and other PCB assemblies using a 2.5 mm four-pole connection. Official 2.5 mm four-pole audio-jack documentation from Kycon likewise identifies this connector format for audio equipment and compact electronic devices.
