Voice-Grade MT-Series Keystone Jacks

 

    KJ126MT-C3U-WH        KJS458TL-CX_Back

 

 

The Signamax Voice-Grade MT-Series Keystone Jacks have been designed to support voice-transmission network applications and low-speed data-transmission applications. These connectors are slim in profile for high density applications and have the ability to mount either color-coded icons for service identification or dust covers to protect unused jacks from dust and other contaminants.

Special design features allow these jacks to be terminated with a standard 110 single-position tool or with the Signamax four-pair tool. The connector contact design provides enhanced plug-to-jack connection integrity, protects against damage caused by insertion of 4- or 6-position plugs, and is rated for a minimum of 750 plug insertions providing for the highest level of system reliability.
