Adaptor coaxial SMA DeLOCK 89991

The DeLOCK 89991 is a compact SMA coaxial adapter intended for 50 Ω radio frequency applications. It has an SMA connector on one end and an RP‑SMA connector on the other, providing compatibility between standard SMA and reverse‑polarity SMA interfaces. The adapter measures 7 mm in diameter and 25.6 mm in width and is supplied individually in a polybag; the housing is gold coloured.

Advantages

The adapter enables reliable connections between SMA and RP‑SMA devices without modifying cables or equipment. Its small size and gold‑coloured finish offer ease of installation in constrained spaces and good corrosion resistance. Being sold as a single unit makes it suitable for targeted replacements or one‑off installations.

Suitable for

• Connecting Wi‑Fi antennas and radio frequency modules with SMA and RP‑SMA interfaces
• Adaptation between standard SMA peripherals and reverse‑polarity SMA connectors
• Use in compact RF assemblies and test setups requiring 50 Ω impedance

How to use

Align the SMA and RP‑SMA connectors carefully and screw the adapter onto each mating connector by hand until firm; avoid over‑tightening. Ensure both connected devices are powered off during installation to prevent damage from static or accidental transmission. After installation, verify continuity and RF performance with appropriate test equipment if required.

Recommendations

For optimal RF performance maintain 50 Ω system continuity and avoid excessive mechanical stress on the connector. Use a calibrated torque wrench if precise tightening is required, and store the adapter in a dry environment to minimise corrosion.
