ProXtend DCDONGLE-5525-SU-MS dongle 5.5 mm to MS adapter

ProXtend DCDONGLE-5525-SU-MS dongle 5.5 mm to MS adapter is a compact interface adapter that converts a 5.5 mm plug connection to an MS connector. It provides a simple physical conversion between two common jack types, allowing devices with a 5.5 mm output or cable to be connected to equipment with an MS input. The small form factor is intended for portable setups, equipment racks and situations where reducing cable bulk and avoiding permanent rewiring is required.

Advantages

The adapter offers a straightforward, passive conversion without active electronics, ensuring signal integrity for compatible audio, power or low-frequency signal applications. Its compact housing reduces strain on cables and connectors and simplifies cable routing in tight spaces. The passive design means no power is needed for operation and it can be used immediately after insertion. Mechanical construction focuses on reliable contact and a secure fit between the 5.5 mm interface and the MS connector.

Suitable for

• Connecting a device or cable with a 5.5 mm plug to equipment that accepts an MS connector
• Temporary connections during testing, troubleshooting or field repairs
• Portable audio setups, small power connections, and signal routing where form factor matters
• Cable management situations where a short adapter is preferable to long custom cables

Key specifications

• Connector conversion: 5.5 mm plug to MS connector
• Form factor: compact dongle-style adapter for inline connection
• Intended signal types: audio, low-voltage power or low-frequency signals (passive conversion)
• Construction: mechanical contacts designed for secure mating and minimal signal loss
• Operating principle: passive adapter—no active electronics or power required

How to use

Insert the 5.5 mm plug into the adapter’s 5.5 mm socket and connect the MS connector end to the receiving equipment’s MS jack. Ensure connectors are aligned and fully seated to establish reliable contact. For power or signal applications, verify compatibility of voltage, polarity and signal levels before connecting to avoid damage. Remove the adapter by pulling straight from the connector without twisting to prevent stress on cable terminations.

Usage recommendations

Use the adapter in environments where mechanical strain is minimal; support cables where appropriate to reduce pull force on the dongle. Confirm that the adapter’s passive nature is suitable for the intended signal or power levels and check device manuals for connector-specific requirements. Store in a dry, dust-free place when not in use to maintain contact quality.
