| The clamping nut is designed to provide a perfect grip. The gold-plated surface prevents any type of corrosion. IC and IEC compliance are achieved by transparent full Makrolon insulation of all live parts. 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
The pole terminal can be directly mounted on to a printed circuit board by means of an anti-fatigue bolt and fan shaped washer. Alternatively, one or more ring terminals can be screwed-on. 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-0766 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.) 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. |
