Allen-Bradley QuadConnect and Pen TUFF Contact Blocks Application Technique

This application technique addresses the issue of diminished switching reliability in low-voltage applications due to oxidation build-up on contacts, which can cause machine downtime. It presents Rockwell Automation’s Allen-Bradley QuadConnect and Pen TUFF contact blocks as solutions, using precious metal spanners and wiping actions to ensure reliable switching down to 5V, 1 mA.
