DC power adapter connector EUROLITE 50532020 — barrel plug to screw terminal adapter

EUROLITE 50532020 is a DC power adapter connector that converts a cylindrical (barrel) plug to a screw terminal connection. It provides a compact and practical interface between devices that use a standard barrel jack and bare wires, allowing a quick change from pre-terminated cables to custom power leads. The adapter is suitable for temporary setups, repairs, and applications where easy disconnection or replacement of the cable end is required.

Advantages

The adapter offers a straightforward mechanical connection without soldering, enabling fast installation and replacement of cable ends. Its compact barrel-to-terminal design maintains the original polarity orientation and provides a reliable contact for low-voltage DC power. Because the connector converts a standard barrel plug to screw terminals, it supports flexible wiring options for prototyping and field adjustments.

Suitable for

• Connecting small electronic devices with barrel jack inputs to bare wires
• Temporary power leads for audio and lighting equipment
• Prototyping and test setups that require easy cable changes
• Repairing or replacing damaged cable ends without soldering

Key specifications

• Connector type: barrel plug (female socket input) to screw terminal adapter
• Intended use: low-voltage DC power connections
• Contact method: screw-clamp terminals for bare conductors
• Housing: compact inline adapter for standard cylindrical plugs
• Polarity: preserves center and sleeve orientation for correct DC polarity

How to use

Insert the barrel plug of the powered device or power supply into the adapter’s barrel socket until it seats firmly. Strip a short length of insulation from the wire ends, insert the bare conductors into the screw terminal openings, and tighten the terminal screws to secure the wires. Double-check the polarity before powering the device to avoid reverse-voltage connection. The adapter can be unplugged or rewired quickly as needed for test changes or equipment swaps.

Usage recommendations

Use the adapter only with compatible low-voltage DC equipment and within the current rating of the wiring and power source. Ensure tight screw connections and appropriate wire gauge for reliable contact. Avoid exposing the adapter to moisture, excessive strain, or temperatures outside the equipment specifications.
