Title: Keithley 236/237/237 interlock connector
Post by: balage on September 16, 2020, 10:27:14 am

Hi Fellowes,

Can anybody help me identify which connector fits the rear interlock connector of the good old Keithley SMUs?

This is the 3-pin version, not the 4 that is used with the picoammeters. I just want to try buying one instead of changing them to LEMOs instantly.

Thanks

Hi,

On the images it seems this is the one I need. And available at Mouser and Digikey.

I will measure the dimensions to be sure, but it must be the one!

Thanks! Recognizing a specific connector on an image - that needs experience. :D
