IP67-, IP68- and IP69K-rated SMA extender cables from GCT provide waterproof connections for use in harsh outdoor conditions. The integral sealing offers a more reliable alternative to the application of self-amalgamating tape.

GCT has introduced sealed SMA extender cables with IP67, IP68, and IP69K protection ratings for use in harsh and challenging environments.  

 

In many applications, engineers have traditionally used self-amalgamating tape to seal SMA connectors or mated pairs in the field. While this method can offer temporary protection, it often results in inconsistent sealing, makes maintenance more complex, and increases downtime during inspections or repairs. 

 

The patent-pending SMA extender cables from GCT offer a fit-and-forget solution, providing consistent sealing performance at both the connector interface, whether mated or unmated, and at cable entry points, without the need to apply additional sealing materials. This simplifies installation, improves reliability, and reduces maintenance requirements over the life of the product. 

 

Available in a variety of standard lengths up to 5 m, these assemblies can also be produced to custom lengths to suit customer requirements.
