RF coaxial SMA female crimp connector by DELOCK for LMR400 cable with heat-shrink sleeve

DELOCK SMA female crimp connector for LMR400 cable is a precision RF connector designed to terminate 50 Ω LMR400 coaxial cable. The connector is a crimp-type SMA female contact fitted with a heat-shrink sleeve to provide electrical insulation and mechanical strain relief. It is intended for antenna connections, radio systems and other RF installations that require a compact SMA female interface and reliable signal transmission on LMR400 cable.

Advantages

This SMA female crimp connector offers stable 50 Ω impedance matching for RF signals on LMR400 cable and a durable mechanical crimp termination that resists loosening under vibration. The integrated heat-shrink sleeve improves insulation and protects the crimp joint from moisture and abrasion. The compact SMA female form factor provides a standardized threaded interface compatible with SMA male components commonly used in antennas, radios and RF equipment.

Key specifications

How to use

Prepare the LMR400 cable by precisely stripping the outer jacket, braid and dielectric to the dimensions recommended for the crimp ferrule and center pin. Insert the center conductor into the crimp contact and position the ferrule over the braid. Use the appropriate crimp tool specified for the connector and cable to crimp the center pin and the ferrule securely. Slide the supplied heat-shrink sleeve over the crimped area and apply heat evenly until it conforms to the cable and connector, providing insulation and strain relief. Finally, mate the SMA female connector with an SMA male counterpart by threading until hand-tight, avoiding over-torquing.

Recommendations

Verify cable preparation dimensions and use a calibrated crimp tool suitable for LMR400 to ensure a reliable electrical and mechanical connection. Use correct heat-shrink size and apply heat uniformly to achieve proper insulation. Inspect the finished termination for secure crimps and full contact alignment before installation in permanent RF systems.
