Cabling made to the point
with keystones

In a modular cabling system keystones can be precisely customized to the user’s needs. Thanks to the uniform design, all keystone modules and housings can be freely combined. In addition to RJ45 jacks, keystone modules from the fiber optic (FO) and multimedia (HDMI, USB) ranges are also available. In addition to the classic patch panel and the network socket, many other chassis solutions are available, which allow a customized scaling and adaption to a wide variety of environments. In addition to data centers and industrial facilities, this includes office cabling or your own smart home. During installation, the simple snap-in mounting saves time and ensures the necessary flexibility - even after the initial installation. Thereby keystones can be mounted practically "tool-free".

RJ45 Keystones

In the area of copper cabling, there is a distinction between keystone jacks and keystone adapters. RJ45 keystone jacks are used to conclude a standard-compliant cabling route. In contrast to the IDC technique, no special tools are required for contacting at the installation. Learn the individual steps in the video tutorial.
Keystone adapters, on the other hand, are used as couplings for already assembled patch cables.

Modules for fiber optics

Adapters for fiber optic cables can be used as keystone modules, as long as flangeless versions are used. An adapter frame is required for installation.

  • Flexibility of keystone mounting
  • Simplex/Duplex/MTP
  • Higher stability through one-pice housing
  • Adapter frame available separately

Multimedia Keystones

Multimedia interfaces play an important role especially in the office or entertainment area. In addition to HDMI adapters, solutions for the various USB specifications and plug faces are also available.


Patchpanel and network outlets

A large selection of chassis is available for mounting the keystones. In addition to the classic patch panel and network outlet, the portfolio also includes other solutions, such as DIN rail mounts, floor tank mounts and surface-mounted chassis. This allows the cabling system to be adapted to almost all environments and scaled as desired.
