Category 5e MT-Series Unscreened Keystone Jacks
The Signamax Category 5e MT-Series Unscreened Keystone Jacks have been designed to meet the need for today’s high-bandwidth applications. These connectors are slim in profile for the highest 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.
The contact design provides enhanced plug-to-jack connection integrity, protects against damage caused by insertion of 4- or 6-position plugs. Special design features allow these jacks to be terminated with a standard 110 single-position tool or with the Signamax four-pair tool, and are rated for a minimum of 750 plug insertions providing for the highest level of system reliability.
