Rated 4 out of 5 by from Pretty much what I was looking for I have a data acquisition unit with voltage inputs. It is connected to a PC on a workbench. I didn't want to be constantly moving the device and PC over to the environmental chamber. The extension allows me log chamber temperature along with various inputs from the product being tested. So time, temp, and performance all come from one device for easy graphing. The extender was exactly what I was looking for other than I didn't need the male connector so I cut off and wired it directly to my device.

Where can I find Type J male to male extension? PN TECJ4-5 no longer exists?

Asked by: Courtney
Hi! The part number can still be purchased. There is a "load more" at the bottom of the page. Another quick way to find is to put it in the quick order and it will come up with a lead time and price. https://www.omega.com/en-us/search/?text=Thermocouple+Extension+Cables+with+Molded+Connectors

How do I connect thermocouple wires like https://www.omega.com/en-us/temperature-measurement/temperature-wire-and-cable/thermocouple-wires/sppl/p/SP10R-005 to this and if I were to cut this cord open how could I connect it to the thermocouple wires?

Asked by: stew
The question is not clear of what you are proposing to do. If you want to add a connector to SP10R-005 you should use a connector like the SMPW-R/S-M to connect to the screw terminals. You can use standard lead wire like EXTT-RS-20 to make extensions as well.
