Hi all,
Just rummaging through eevblog re Fluke 8505 and found a question I could actually answer!
The rear panel input socket is a 516 series 20 pin female connector made by EDAC.
The mating plug is available as a 20 pin housing with the screwlocks, solder pins and the connector shell are seperate items.
20 pin body : EDAC 516-020-000-302
solder pins : 516-290-500
plastic shell : 516-230-520
metal shell : 516-230-620
