card and solder BENEFITS

• No wire management fixtures required

• Simultaneous stripping of four pairs

• After stripping, cable lays directly on PCB pattern

• Fixed position of wire distribution allows easy automation

For more details go to www.3Mtwinax.com. Select Product Information

then open Twin Axial Cable Preparation under the ‘Instructions’ section.
