Description

This panel-mount DC barrel power jack provides a reliable DC power input solution for equipment panels, industrial enclosures, custom chassis, desktop power panels and test instrument front panels. It allows external DC power adapters, power supplies and battery packs to connect directly through the panel without opening the enclosure, making it widely used in industrial control equipment, LED displays, communication devices, test instruments, DIY electronic projects and custom power supply systems.

The connector features a standard barrel socket structure with an outer contact and an inner center pin, providing stable DC power transmission between the external power plug and internal device circuit. The metal flange, threaded body, locking nut and washer ensure firm installation on panels with standard cutouts, offering good vibration resistance and long-term connection stability in industrial environments.

This DC power jack is available in multiple common sizes to meet different application requirements. The 5.5×2.1mm and 5.5×2.5mm versions are widely used for medium-power DC input, while the 3.5×1.3mm version is suitable for smaller devices and low-power applications. Customers can select the appropriate size according to plug diameter, center pin diameter, current load and panel cutout size.

Constructed with metal housing and high-conductivity contacts, this panel-mount DC socket offers low contact resistance and good current-carrying performance. The insulator provides reliable separation between the outer contact and the inner center pin, helping to prevent short circuits and ensure safe power input. It is available in solder lug, PCB pin and wire harness versions, supporting different internal connection methods.

It is widely used for industrial equipment power input, LED driver panels, communication device power ports, test instrument power sockets, custom chassis front panels and desktop power distribution projects. The connector supports both permanent panel integration and prototype installation, making it suitable for equipment manufacturers, system integrators and electronic project builders.

Standard options include 5.5×2.1mm, 5.5×2.5mm and 3.5×1.3mm, with metal or black housing finish. Bulk orders can be customized with size, current rating, connection type, mounting thread length and private-label packaging.
