DeLOCK 91791 coaxial connector

This jack by DeLOCK with matching shrink tube is suitable for connecting components of radio frequency technology. The coaxial connector is an RP‑SMA type with gold-plated brass contacts, designed for 50 Ω installations and supplied as a single piece in a polybag. Dimensions are approximately 8 mm (W) × 8 mm (H) × 19.5 mm (D).

Advantages

The RP‑SMA connector provides a secure threaded connection for RF applications and the gold-plated brass contacts improve corrosion resistance and electrical conductivity. Its compact size and standardized 50 Ω impedance make it compatible with common RF equipment. The shrink tube included simplifies insulation and strain relief during installation.

How to use

Slide the included shrink tube over the cable before fitting the connector. Mate the RP‑SMA jack to the corresponding RP‑SMA plug and tighten the threaded coupling by hand; use a torque wrench if specific torque is required to avoid overtightening. Position the shrink tube over the joint and apply heat to shrink it for insulation and strain relief. Verify continuity and correct impedance with appropriate test equipment after installation.

Recommendations

Use this RP‑SMA connector in 50 Ω RF systems and avoid exposure to excessive mechanical stress or moisture. For reliable performance, ensure clean contact surfaces and proper torque when tightening; verify connections with a network analyzer or multimeter as needed.
