I'll dig through > the old inventory again . . . Hmmmm . . . did an archeological dig through the 'inventory'. Seems we never did work a task with that technology on a 0.100" pitch. I'm a bit surprised that the original designers applied open-barrel, crimp pins for grabbing thermocouple wires. Achieving gas-tight connections with longevity is relatively easy with copper terminals mashed down on copper conductors. Not so easy with thermocouple wire having much greater harness than copper. I've never attempted to incorporate anything less than 4-quadrant, closed barrel pins on thermocouples. Ebay is always worth a look. Molex edge connector My permanent solution, for experimental applications, is a soldering iron, some milspec wire, and a subD connector. Charlie Agreed. This work-around calls for creating a pendant cable terminated in a d-sub connector. Appliance end is soldered directly to the ecb connector traces. Use 19 strand wire (re: mil-spec reference). Expose only the smallest practical stranding length (~0.050") and tack it onto the trace with the deepest positioning possible. Then strain relief the row of wires right to the ECB with E-6000. I may have some pictures around her illustrating that techique. Terminate far end with a 15-pin, d-sub incorporating solid, 4-quad crimped pins. I'll venture a guess that electron gods willing and other failures don't rise, you just might coax a few more decades of service out of this electro-whizzy. Good luck! Bob . . . BTW, I've got shells, pins and tools to loan if you elect to go this route. ________________________________ Message 2 _____________________________________ Time: 08:41:25 AM PST US From: Charles Kuss Subject: Re: AeroElectric-List: Amp [was Molex] connector needed for my Insight GEM 602 I found the part number for the GEM 602 electrical connector. I had the ma nufacturer wrong. It is Amp P/N 583861-9, which is obsolete. A Google searc h turned up the following web link. This item appears to be unavailable. https://www.te.com/usa-en/product-583861-9.html Jim at Insight got back to me. There is an updated part number. It is P/N 1 -583861-1 . It is available through Digikey. https://www.digikey.com/en/products/detail/te-connectivity-amp-connectors/1 -583861-1/2261692?s=N4IgTCBcDaIIwFoCsAOAzCgbIuIC6AvkA Charlie On Monday, May 30, 2022, 02:49:35 AM EDT, Robert L.
