Inbouw-gelijkstroomadapter DELOCK 5,5x2,1mm naar 5,5x2,5mm, model 91119

DELOCK panel-mount DC jack adapter converts a 5.5x2.1 mm male plug interface to a 5.5x2.5 mm female jack, enabling compatibility between devices and power supplies with slightly different barrel sizes. The adapter is intended for installation into equipment panels, providing a fixed, stable DC power inlet that maintains electrical contact and mechanical stability where a direct connector match is not available. Its compact design suits retrofit tasks and workshop fixtures where a permanent or semi-permanent power entry point is required.

Advantages

The adapter offers a simple, reliable method to adapt a 5.5x2.1 mm plug to a 5.5x2.5 mm jack without modifying cables or power supplies. Panel-mount construction secures the connector to the chassis, reducing strain on wiring and preventing accidental disconnections. The mechanical fit and materials are selected to ensure consistent electrical contact and steady power transfer during typical device operation.

How to use

Drill or use an existing panel opening that matches the adapter’s mounting diameter and insert the adapter from the front. Secure the adapter to the panel with the supplied nut or an appropriate fastening method to ensure it sits flush and does not rotate. Connect the internal wiring to the adapter’s terminals according to the device’s polarity requirements, observing correct center-positive or center-negative wiring. After secure mounting and wiring, plug the 5.5x2.1 mm male connector into the exposed 5.5x2.5 mm jack to establish the DC power connection.

Recommendations

Verify the voltage and current ratings of the power supply and device before use. Ensure correct polarity when wiring the adapter to internal circuitry to avoid damage. For permanent installations, periodically check the mounting and contact condition to maintain reliable power transfer.
