Pre-Assembled Feedthrough Rack Panels

Most popular feedthrough connectors and accessories.

From CLIFF Electronics.



CLIFF Electronics, leaders in the design, development and manufacture of connectors and test equipment, have developed a wide range of feedthrough and conventional connectors, designed to be mounted in the industry-standard, 24 mm diameter, XLR panel cut-out. With over 20 different connector types now available in this standard format, panel design and manufacture is greatly simplified. Cliff’s feedthrough connector design allows standard, off-the-shelf, cables to be used for internal connectivity, further simplifying assembly.

Cliff’s feedthrough connector range allows designers to integrate audio, video, digital, optical, networking and data feeds into professional equipment for broadcast (studio and mobile), lighting, audio, industrial applications, instrumentation and control connectivity.


To further aid product designers and systems integrators, Cliff can now supply 1U × 19″ rack panels preassembled with up to 16 connectors to meet the end system’s requirements. Specifying preassembled connector panels assists systems integrators by simplifying and speeding up assembly time while reducing component count and cost. Cliff’s rack panels feature a connector labeling strip located on the front and a cable strain-relief bar is fitted at the rear to secure internal wiring against stretching and vibration.


The most popular connectors in Cliff’s feedthrough range are:

  • Cat.5e RJ45,
  • Cat.5e shielded RJ45,
  • Cat.6 RJ45,
  • Cat.6 shielded RJ45,
  • HDMI female-to-female,
  • USB 3.0 A-to-A,
  • USB 2.0 B-to-A and
  • USB 2.0 A-to-A.

All widely used in data and audio-visual applications.


A range of dust covers is now available to protect unused connectors from the ingress of dirt. Push-in types in black or white may be used with RJ45 connectors and gasket style versions in red, black and blue are suitable for the rest of the connector range.


Pre-assembled rack panels available from Cliff feature 16 of their market leading, feedthrough connectors each and are available in the following configurations:

  • 8 male and 8 female 3-pin, front-mounted, XLR sockets,
  • 50Ω, 75Ω and 75Ω gold, insulated BNC,
  • Cat6 and Cat6A RJ45,
  • HDMI-A to HDMI-A,
  • USB2-A to USB2-B and
  • USB2-B to USB2-A.
  • Fibre Fiber optic connector types
    • ST / BFOC,
    • LC duplex
    • SM and LC duplex MM.


Two other non-feedthrough versions are mounted with XLR-3DCM and XLR-3DCF connectors.


Cliff rack panels may also be supplied without connectors for end users to mount their own single or mix of connector types. Any connector with the standard 24 mm diameter XLR panel cut-out may be fitted.


Suitable for instrumentation and control.


John Hall, Managing Director of CLIFF Electronics, comments, “As applications for pre-assembled rack panels continue to grow we increase our understanding of the market and can improve our products and customer service.
