Panel-mount DC 5.5×2.1 mm socket to DC 5.5×2.1 mm plug, DELOCK 91116

DELOCK 91116 is a panel-mount adapter that provides a fixed DC power pass-through by connecting a DC 5.5×2.1 mm socket to a DC 5.5×2.1 mm plug. Intended for installation in panels, cabinets or enclosures, this adapter creates a stable and accessible connection point for devices that use the standard 5.5×2.1 mm barrel connector. The simple construction supports common power distribution and external power supply connections in industrial, commercial and residential setups.

Advantages

The adapter offers a compact, low-profile mounting solution that secures the DC connection within a panel opening, reducing wear on portable connectors. Because it uses the widely adopted 5.5×2.1 mm format on both sides, compatibility with existing power supplies and device cables is straightforward and predictable. The panel-mount format improves cable management and prevents accidental disconnection while maintaining easy access for service or replacement.

Key specifications

How to use

Drill or prepare the appropriate panel cutout and insert the adapter so that the housing seats securely in the opening. Fasten the adapter according to the panel thickness and mounting method provided by the enclosure, ensuring a firm mechanical fit. Plug a DC 5.5×2.1 mm male connector from the external power supply into the rear or external side as required, and connect the device cable to the front socket. Verify polarity and voltage of the power source before connecting the device to avoid damage.

Recommendations

Use this panel-mount adapter only with low-voltage DC power supplies and cables that match the 5.5×2.1 mm dimensions and correct polarity. Ensure the mounting location provides strain relief for connected cables and prevents exposure to liquids or excessive vibration. For installations in regulated environments, consult applicable electrical standards and verify that the adapter meets your system's mechanical and electrical requirements.
