IDEAL Keystone Jacks are high performance modular jack connectors designed to exceed the requirements of ANSI/TIA-568-C.2 giving installers the ability to use these products in residential and commercial installations for applications such as Gigabit Ethernet.

All jacks feature a robust internal printed circuit board design used to help reduce NEXT (near-end cross talk) and improve RF performance at higher frequencies.  The IDC tower design and layout help to simplify and speed up the wiring and termination process. Tapered tower tops help to separate each pair into the individual IDC slot without the need to untwist each pair. This allows pairs to easily maintain the recommended maximum of 1/2“ of untwisting per pair from the cable jacket.

Twisted pairs stay together. With the PCB design, each color pair is terminated side by side, in a consistent pattern. Less time spent untwisting, separating and routing individual conductors to the IDC contacts.

These CAT3 Voice Grade Jacks feature a standard RJ-45 port that accepts both RJ-45 (8P8C) and RJ-11/12 (6 position) modular plugs.  The jack has 6 active IDC contacts for use with 1, 2 or 3 line phone/fax/data lines. 

Jacks have the USOC wiring diagram and pinout pre-labeled at each IDC location.

The IDEAL Keystone Jacks have an industry standard (14.5mm x 16mm) profile interface and latch location so they are compatible with many other keystone style sized panels, racks, and plates.

Standard midsized (2.75“ x 4.75“) faceplates in both white and ivory colors are available in 1, 2, 3, 4, 6 and 0 port configurations. Blank inserts can be used to fill in unused faceplate ports.
