• 75 ohms (typ.) characteristic impedance
• Totally distortion-free (no eddy currents)
• Ultimate conductivity (signal conductor made of high-purity silver)
• Inner contact designed as tulip contact with spring ring
• Outer contact in the form of a pat. double wave contact

75-ohm characteristic impedance means that these sockets not only transmit superb analogue signals but also outstanding digital audio and video signals. The transmission bandwidth is 1 GHz.

The contact elements of the connector are made of high-purity silver, the best electrical conductor of all, in order to ensure optimum signal transmission. The metal is passivated so that the surface does not oxidise and impair contact quality.

The inner contact is an active spring contact. The newly developed three-segment tulip contact is pressed onto the central pin of the RCA plug by a surrounding double bronze spring ring. Not only does this ensure reliable contact with non-standardised RCA plugs but contact also remains reliable even after the plug has been connected and disconnected many times over.

The outer contact is in the shape of a double wave which encompasses the socket element made of robust Ultramid*. This wave shape guarantees reliable contact with any RCA plug. In addition, the reduction in the amount of conductor material to the absolute minimum prevents the creation of eddy currents, enabling the WBT-0210 to transmit signals that are totally free of distortion.

Eddy currents occur in metal components near to which alternating current flows. These currents can result in major signal distortions.

Specifications:

• 75 ohms (typ.) characteristic impedance
• Totally distortion-free (no eddy currents)
• Ultimate conductivity (single-piece signal conductor made of pure copper)
• Absolutely reliable signal transmission thanks to patented WBT clamping mechanism
• 2-section clamping sleeve in cobalt blue

75-ohm characteristic impedance means that these plugs not only transmit superb analogue signals but also outstanding digital audio and video signals. The transmission bandwidth is 1 GHz.

Eddy currents occur in metal components close to where alternating currents flow. These currents can result in major signal distortions. The WBT-0110 Cu is designed in such a way that eddy currents do not occur at all.

The contact elements of the plug are made of high-purity copper, one of the best electrical conductors, in order to ensure optimum signal transmission. The metal is nickel-free gold-plated so that the surface does not oxidize and impair contact quality.

The clamping mechanism, which works in the same way as the chuck device in a drill, firmly clamps the outer contact against the RCA socket. The high clamping pressure not only guarantees a secure connection but also minimises transition resistance.

The clamping sleeve is designed with two sections so that the front section moves freely as the rear section is turned. This eliminates the risk of torsional strain on the contact elements. The pressure wedge between the contact and the sleeve is made of plastic, which means that the sleeve is completely insulated and cannot influence the signal.  In addition, any size variation in the outer contact of a socket is compensated for, thereby ensuring a perfect fit.  

The central pin is slotted and ideally formed thereby giving a firm yet elastic contact which ensures lasting and reliable electrical connection with absolutely minimal transition resistance.

The central contact element can be removed to facilitate cable soldering. WBT provides a special nextgen tool for this purpose to OEM customers. WBT recommends the surface friendly silver solder WBT-0800 (see also solder connection).

A Torx screw provides reliable cable strain relief.

nextgen™ -  new generation of WBT RCA connectors

The basic element having influence on the sound quality of WBT-0152 Cu is the Central Contact Unit which has been developed exactly the same way as for the plug model WBT-0110 Cu: minimal mass of signal conductors made of highly pure copper. Copper was chosen as one of the best electrical conductors which provide not only an ultra rapid signal transmission, but also an excellent fine resolution. This metal is of course nickel-free gold plated so that the surface does not oxidize which would affect the contact quality.

WBT-0152 Cu lies with its transmission bandwidth of up to 200 MHz far in excess of the transmission bandwidth of conventional RCA plugs.

Through the collect chuck device which works like a chuck of a drill machine the plug’s outer contact once inserted clamps firmly to the RCA socket. The maximum contact pressure provides not only a secure connection, but also minimizes the transition resistance.

Thanks to the two-piece clamping sleeve the sleeve’s cone does not turn while the clamping sleeve is tightened and thus the contact elements are not exposed to twisting pressure. Besides, this way dimension inaccuracy of the outer contacts of the female sockets are compensated for.

The centre pin is slotted and slightly bent up and thus guarantees with its firm spring feature a long-lasting secure electrical connection with lowest transition resistance possible.

The body element is made of brass (nickel-free gold plated) in order to accept rigid and particularly thick cables. The metal connector body is of course electrically uncoupled from the central contact unit und is made of as little metal as possible so that also WBT-0152 Cu is free from eddy current to a large extent.

Other than for digital outputs it is very important for phono outputs (record players, microphones) to have a good shielding against electromagnetic interfering fields. The undesirable interspersions can be very high depending on the nature of the devices and first of all on what they are surrounded by (cellular phones, computers etc.). WBT-0110 nextgen™ pure was designed as the perfect RCA plug for digital links, the new WBT-0152 Cu optimizes analogue connections. WBT-0152 Cu has the more conductive and with the minus contact element connected brass clamping sleeve in order to provide the necessary electromagnetic shielding.

The basic element having influence on the sound quality of WBT-0152 Ag is the Central Contact Unit which has been developed exactly the same way as for the plug model WBT-0110 Ag: minimal mass of signal conductors made of fine silver. Silver was chosen because of being the best electrical conductor which provide not only an ultra rapid signal transmission, but also an excellent fine resolution. The signal conductors are passivated and thus best possibly protected against corrosion or migration which would affect the contact quality.
