ADDITIONAL FEATURE


The transmission paths can be used universally for power or signals.

The PIN assignment by itself ensures that paths for signal transmission are always at the top,especially in the vertical installation position, and cannot be impaired by the abrasion of transmission paths above them.

As additional protection, labyrinths are located between all transmission paths to prevent abrasion from falling onto lower rings.
