Product Image: WBT-0730.11
Polished, gold-plated
Profile in brief: WBT-0730.11:
  • Extremely high contact pressure for spades thanks to fine thread and cross-milled surface
  • Pat. two-piece clamping nut for maximum strength of connection
  • Solder or crimp connection with Torx screw
  • 24 carat direct gold plating (nickel-free)
  • Max. constant current 70 A
  • Twist-proof mounting
  • Puzzle plate system

Product description:

Product for the most exacting requirements in terms of signal transmission, mechanical stability and design

Superb mechanical properties, solid design and the two-piece clamping nut with rotatable pressure piece ensure high contact pressure and hence consistently low transition resistance – the precondition for absolutely minimum effects on sound quality. The elegant design of the pole terminal is further enhanced by the shiny gold-plated surface that reliably prevents corrosion. The pole terminal is polished prior to gold-plating, creating an extremely robust and abrasion-proof surface.

Outer connection
>> 4 mm banana plug

A 4 mm banana plug can be connected in the front part of the clamping nut.

>> Spades and crimped cable ends (up to 6 mm²/9 AWG)

You can use the patented WBT clamping nut system to make high-pressure spade and crimped cable end connections. The cross-milled surface on the bottom of the pressure piece creates a permanently secure connection with extremely low transition resistance. It also prevents the splitting of cable strands if exposed cable ends are used.

Inner connection
Cables with a conductor cross section of up to 10 mm² (7 AWG) can be used on the inside.
WBT recommends the crimp connection method. You can use the supplied Torx screws and the Torx T.6 wrench to perfectly fix crimped cable ends.
The connections can also be soldered, however. If you decide on soldering, WBT recommends the surface-friendly silver solder WBT-0800 (see also solder connection).

Mounting
Mounting insulators are supplied and ensure not only insulated but also twist-proof mounting and polarity identification. Counter nuts, double step washers with lug and puzzle plates are also supplied. The puzzle plates can be clipped into one another. This ensures precise terminal spacing of 19 or 30 mm, but above all absolute torsion protection. The nuts on appliances with high intrinsic mechanical vibration levels like loudspeakers should be additionally secured – using the WBT serrated lock washer WBT-9150, for example. In case a fixed distance of 19 mm is required, one may use the spacer WBT-9404 and install the WBT-0730.11 as a double terminal. Thanks to the locking slots in the spacer the inlet opening for the connection cable can be rotated in steps of 45°.
(WBT-9404 is supplied with each end consumer package, but in general needs to be ordered separately.)

Explanatory notes:

Hint for OEMs
Due to the current safety regulations, the 4 mm banana holes of WBT pole terminals should be closed using the safety stick WBT-0799.
