SHX subminiature connectors are ideal for use with fine gage thermocouple wires in applications where high temperatures are required. The SHX connector is permanently dot-coded to conform to ANSI and OMEGA standards for applications such as high vacuum furnaces where contamination would adversely affect the process, USHX connectors are shipped with a removable color-coding dot. Two-piece ceramic construction assures long life, while the oversized terminal screws allow for easy wiring.
Rated 4 out of 5 by from Works as advertised Connectors work as advertised although being ceramic they crack easily with rough handling. Note: Strain relief clamps are also needed to facilitate holding the attached cable in place.

Rated 3 out of 5 by from Hight temp connector I like the firm hold on the connectors but did not realize how fragile the cover assembly is. I broke the cover with only moderate tightening of the screws. I was a little more cautious on the next assembly and it was ok.

What is the screw size used on ceramic mini thermocouple connectors, to install cover?

Asked by: Geo1
Hi Geo1 Thank you for the inquiry. The terminal screw is a 3-48 x 3/16 long combo pan head and the cap screw is a 2-56 x 1/4 long filister head combo screw. Best regards OMEGA

We are having the screws for the thermocouple wires loosening up after some time. The connectors USHX-K see 125 Deg to 25 Deg C in an oven. Is there a method to stake or secure the screws?

Asked by: AAFG
Thank you for the inquiry. We do not have a securing method unfortunately. Torque spec for the screws are 3.9 inch-pounds. Best regards OMEGA

What does the term 'temperature range' imply? Does it refer to the maximum temperature that all components can withstand, or is it specifically associated with the calibration temperature range? Can a 260°C connector withstand a 400°C baking process?

Asked by: SNPY
Concerning temperature range of connectors it is the exposure temperature they can endure so if it is rated to 260C that is it's maximum temperature it can withstand.
