Philmore 247B — Panel-Mount DC Power Jack, 2.1mm x 5.5mm

The Philmore 247B is a panel-mount DC barrel jack designed to accept standard 2.1mm I.D. x 5.5mm O.D. power plugs, providing a clean, reliable low-voltage power entry point for enclosures, instruments, and embedded devices. Its front-mount design fits a 0.50″ chassis hole for quick, consistent installations on project boxes and production panels.
