You need to talk to the Tyco engineer to verify how the connector was qualified and on what tooling. With the fine stranding the Tyco engineer may suggest different crimp dies or connector. Fred Miller -----Original Message----- From: TechNet [mailto:[log in to unmask]]On Behalf Of Forrester, Michael (H USA) Sent: Monday, April 06, 2009 12:05 PM To: [log in to unmask] Subject: [TN] Wire Crimps: Machine Vs Hand Tool Specs We have an application that uses a tyco 350550-2 crimped on connector. It is being crimped onto a 14AWG wire made up of 1050 strands of 44 AWG wire. The wire has a nom. wall of .015" and an nom OD of .115". The standard pull test calls out for min 50 lbs. If we crimp it in automated machines per spec to .069" crimp height, we fail the pull test at an avg of 47 lbs. If we hand crimp it to spec at .063", we get a pull strength avg of 55 lbs., which passes. Due to the volume, the automated machine process is preferred. I have two questions: 1) Why are the automated and hand tool crimp height specifications different? 2)Is there an issue with just setting up the automated tool to the hand tool crimp height specifications? Thank you. Best Regards, Michael Forrester Sr. Product Engineer Siemens Healthcare Diagnostics 101 Silvermine Rd.
