Copper Link Bayonet Connector

The new Copper Link Banana connector from ETI Research features up-to-date styling with the reliability of beryllium copper (BeCu). The connector uses a sawtooth style, often referred to as a Z-plug or BFA connector.


The unique shape combined with the natural resilience of BeCu creates a near seamless connection between the plug and terminal.

The aluminium housing in matte black is consistent with the design changes made to the ETI Research Copper Link RCA. A more streamlined look supports the housing’s excellent shielding properties, eliminating impacts on sound quality. Left and right channels are clearly designated with enamel rings.

Unlike similarly designed connectors, a double strain relief system is employed to establish a more reliable and secure connection. The bare wire of the cable is secured with twin screws into the chamber at the base of the sawtooth (no soldering is required).

A second set of twin screws in the aluminium housing allows the connector to be secured to the insulation of the cable.

Whether you want to terminate patch cords for electronic test equipment or connect a speaker cable, the Link Banana offers quality sound, value for money and superb reliability.

ETI Research Copper Link Banana Connector features:

  • Tellurium Copper Conductor
  • Black anodized aluminium housing
