043701.5WR

The 043701.5WR from Kycon is a 5.5mm x 2.5mm DC power barrel jack connector with right-angle through-hole mounting. Rated for 15A at 24VDC, it handles high-current power input for industrial and networking equipment. The 5.5mm x 2.5mm barrel size is one of the most common DC power connector dimensions, ensuring compatibility with standard AC adapters. A switched contact detects plug insertion for power-source selection circuits. The nickel-plated shell provides EMI shielding and mechanical durability, while gold-plated contacts ensure reliable low-resistance connection.

The 043701.5WR is a coaxial barrel jack connector with a center pin (positive contact) and an outer sleeve (negative/ground contact). When a matching 5.5mm x 2.5mm barrel plug is inserted, the center pin makes contact with the plug’s center conductor, and the outer spring contacts grip the plug’s outer sleeve. An additional switched contact is connected to the center pin when no plug is inserted and disconnects when the plug is inserted, enabling automatic switching between external and internal (battery) power sources. The right-angle orientation routes the cable parallel to the PCB, saving vertical space.
