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. In addition, any size variation in the outer contact of a socket is compensated for, thereby ensuring a perfect fit.

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 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 metal parts are made from a special copper alloy and are 24 carat gold-plated to prevent oxidation, which could negatively impact on contact quality.

Despite the limited space, the WBT-0147 can be soldered with ease. The solder connection for the positive pole is on the front side, the connection for the negative pole on the rear. The poles are kept separated by Teflon* acting as a dielectric, an advantage when the connecting cables are soldered, even with the higher soldering temperature of lead-free solder. WBT recommends the surface friendly silver solder WBT-0800 (see also solder connection).

When combined with WBT RCA sockets, the contacts are positioned in such a way that the outer conductor is in contact before the inner conductor, thereby preventing undesirable or even harmful voltage peaks.

A Torx screw provides reliable cable strain relief on the cable.
