DeLOCK 89970 Wire Connector

The DeLOCK 89970 wire connector offers a compact SMA-type connection with gold-plated contacts to ensure stable electrical contact and improved conductivity. Designed with an outer diameter of 5.5 mm and a depth of 18.9 mm, this single-piece connector is supplied in a polybag for straightforward handling and storage. Its gold colour finish matches typical RF and coaxial accessory aesthetics and supports reliable signal transmission in applications requiring SMA interfaces.

Advantages

Gold plating on the SMA contact surfaces reduces contact resistance and improves long-term corrosion resistance compared with plain metal finishes. The small form factor with a 5.5 mm outer diameter and 18.9 mm depth allows integration in tight cable runs and compact assemblies. Supplied as a single unit in a protective polybag, the connector is easy to store, transport and use for one-off replacements or small-scale installations.

How to use

Prepare the cable according to the SMA connector assembly requirements, ensuring correct stripping length and conductor exposure. Slide any necessary ferrules or sleeves onto the cable before inserting the conductor into the connector body and secure the connection per standard SMA termination practice. Verify the mechanical fit and electrical continuity after assembly to ensure low contact resistance and stable signal transmission. Dispose of packaging responsibly after installation.

Recommendations

For consistent RF performance, use this connector with compatible SMA mating parts and maintain clean contact surfaces. Avoid excessive torque when tightening to prevent damage to the connector body and mating threads. Store unused connectors in dry conditions and in original or similar protective packaging to prevent contamination or corrosion.
