R125812001 - SMA male protective cap with chain

Threaded protection for SMA female connectors

This threaded protective cap is manufactured as a stainless steel nut designed to mate directly with the thread of SMA female connectors. The threaded connection provides stable and secure protection of the interface when the connector is not in use.

Mechanical thread compatibility

The SMA thread allows mechanical compatibility with 3.5mm and 2.92mm (K) interfaces, according to the dimensional specifications of the connector. This compatibility is strictly mechanical and does not imply electrical equivalence between the different connector series.

Panel retention and protective function

The chain allows permanent attachment to the panel or supporting structure, preventing loss of the component during opening or maintenance operations. This configuration is typically used to protect panel-mounted terminal connectors in RF and industrial applications.

Application context and technical use

The protective nut is intended for applications where reliable protection of the interface against dust, particles and contaminants is required, while maintaining connector accessibility and without affecting the mechanical or electrical characteristics of the system.
