ERNIPRESS Power Tap Connector for Pressfit Backplanes General The use of the pressfit termination technique is a widely accepted, high quality and economical method for making connections on a system backplane. For the connection of power supply cables, ERNI has developed the 2-row Power Tap connector with this preferred compliant pressfit termination. The power supply cables can be connected through either terminal lugs to the screw mount type or with slip-on receptacles to the slipon tab type of the Power Tap.

The screw mount cable type accommodates a M3 or M4 screw.
