Cat.3 RJ11 / RJ14 Feedthrough Connector

Widely used connector available for panel mounting from CLIFF Electronics’ growing feedthrough range.



CLIFF Electronics’ comprehensive range of market-leading feedthrough connectors, supplied in the industry-standard, 24 mm diameter, XLR-panel-cut-out, now includes the very popular Cat.3 RJ11 / RJ14 connector, offering users a panel-mount option.


CLIFF RJ11 / RJ14 6P4C connector


The RJ11 / RJ14 is the most widely implemented connector in telecommunications and commonly used for connecting a telephone with one or two lines.


Commonly used for one or two telephone lines.


The Cliff Cat.3 RJ11 / RJ14 connector is a true feedthrough with connections on both sides. Versions are available with plain or countersunk mounting holes to facilitate assembly on either side of a panel.


John Hall, Managing Director of CLIFF Electronics, comments, “Cat.3 RJ11 / RJ14 6P4C connectors sell in very high quantities and adding them to our panel-mounted feedthrough connector range offers OEMs and systems integrators simpler and faster assembly.”.




The Cat.3 RJ11 / RJ14 6P4C (6 positions, 4 contacts) connectors can be incorporated in pre-assembled 19″ rack panels together with other types of Cliff feedthrough connectors to meet bespoke connectivity requirements or make patch panels.


The Cliff feedthrough series of true, feedthrough, data connectors for 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 common, standard cabling for front and back connections with no soldering or screw terminal connections required. Feedthrough connectors may be mounted from the front or back of a panel and a low rear profile accommodates the tightest behind-the-panel spaces. Pre-assembled 19″ rack panels fitted with a range of feedthrough and standard connectors are available from Cliff to simplify end 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 and 50 ohm BNC versions, USB2 A-to-B and B-to-A changer sockets 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 Cat.6 and Cat.5e, (shielded and unshielded), TOSLINK and RCA phono. phono / cinch.
