The Cliff FT series of true, feedthrough, data connectors for audio, video, electrical and electronic instrumentation are perfect when developing custom I/O configurations for wall plates, enclosures, rack panels etc. All fit within a standard XLR panel cut-out and use standard cabling for front and back connections with no soldering or screw terminal connections required. Feedthrough connectors have countersunk or threaded M3 mounting holes and may be assembled from the front or back of a panel. A low rear profile accommodates the tightest behind-the-panel spaces.


Key specifications

  • Bandwidth: 12 GHz.
  • Impedance: 75 Ω.
  • Frequency range: 0 to 18 GHz.
  • Dielectric withstand voltage: 1500 Veff.
  • Insulation Resistance: 5000 .
  • Operating temperature: −35 to +70 °C.
  • Contact retention: 10 N minimum.
  • Mating cycles: 500 minimum.


High reliability, low contact resistance connector for sensors, instrumentation, test and measurement.


John Hall, Managing Director of CLIFF Electronics, comments, “Our gold-plated BNC connector offers our customers a 4K-video-standard connector for future-proofing broadcast systems and patch panels. It offers industrial users a high reliability, low contact resistance connector for sensors, instrumentation, test and measurement. We can also supply our new gold BNC connectors pre-assembled into rack panels offering systems integrators fast and convenient system assembly.”.


Cliff’s XLR-format connectors take advantage of the standard 24 mm diameter panel cut-out widely used in audio and broadcast systems. This is increasingly popular in instrumentation, medical and industrial applications due to the format’s flexibility, security and reliability. Blank socket plates are also now available for customers to create custom connector solutions.


Available versions include RJ45, HDMI, BNC and USB3.0 compliant single and dual versions. Analogue, digital and optical feedthrough connectivity is available in formats including Firewire, HDMI A-to-A, 50 and 75 ohm BNC versions, USB2 A-to-B and B-to-A changer sockets, high speed USB type-C and USB3 to USB3 in various configurations. Also available are popular data and ethernet connectors including LC and SC fibre, fiber, (Duplex and Simplex), UTP and FTP RJ45s in both Cat6 and Cat5e, (shielded and unshielded), TOSLINK and RCA phono. phono / cinch.




All versions of Cliff XLR-footprint connectors are in full production and available direct or via major worldwide distributors.
