Connector SMA female crimp DELOCK 91783 for coaxial RG‑174/RG‑316 with heat‑shrink sleeve

DELOCK SMA female crimp 91783 is a coaxial connector solution for terminating RG‑174 and RG‑316 cables. The connector uses a crimp-style attachment for a secure electrical and mechanical connection and comes with a heat‑shrink sleeve for additional environmental protection and strain relief. It is intended for RF signal paths where a standard SMA female interface is required, providing a compact and industry-compatible termination for antennas, radio equipment, GPS modules and test instrumentation.

Advantages

The crimp termination offers consistent mechanical stability and repeatable impedance performance when properly installed. The included heat‑shrink sleeve improves moisture protection and reduces cable movement at the termination point, helping maintain connector integrity over time. The SMA female form factor provides a widely used threaded interface compatible with common SMA male connectors, enabling straightforward integration into existing RF systems.

Key specifications

How to use

Prepare the RG‑174 or RG‑316 cable by stripping the outer jacket, braid and dielectric to the dimensions appropriate for the connector body. Slide the heat‑shrink sleeve over the cable before assembly. Insert the cable center conductor and dielectric into the connector until it seats properly, then crimp the ferrule using a compatible crimp tool rated for the ferrule size. After crimping, position the heat‑shrink sleeve over the joint and apply heat to shrink it in place, forming a protective seal and providing strain relief. Inspect the assembled connector for proper seating and ensure the SMA female threads and center contact are free of debris before use.

Recommendations

Use the recommended crimp tool and die size for reliable electrical contact and mechanical retention. Avoid over‑stripping the cable to preserve shielding and impedance. For applications exposed to moisture or mechanical vibration, ensure the heat‑shrink is applied fully and consider additional sealing measures if required. Verify continuity and return loss with appropriate test equipment after assembly to confirm a correct termination.
