The key to quality, inherent in these sandwich spades, is the patented design of their contact forks. An elastomer between the signal conductor and non-magnetic steel cap provides constant high contact pressure. Transition resistances are minimised and vibrations successfully absorbed.
WBT-0661 & WBT-0681
Elastomer oscillation dampers eliminate airborne noise and mechanical vibrations This ensures almost total suppression of contact microphonics and there is no interfering ancillary noise. The sandwich design of the contact forks with elastomer inserted in a steel cap generates high and uniform contact pressure while minimising transition resistance. The quality of signal transmission is markedly improved, particularly with high currents or small voltages.
