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.

Rated 5 out of 5 by from High temp Type K (male) Used in a 600C muffle furnace application. Does it's job well after a couple weeks so far. Will update if anything happens in the future, 8/10/23

Rated 5 out of 5 by from Reliable performance at high temperatures These connectors perform well under environments well above temperatures where plastic connectors fail. Their reliability is critical in our high temperature heat exchanger testing.

Rated 3 out of 5 by from High temp performance at a cost. These thermocouple connectors are some of the highest temperature connectors you will find on the market. However, they are very fragile due to their ceramic nature and we found they will break not only when dropped but also if you're not careful tightening the screws. The lids are kept on through captive nuts, but many of the nuts were loose during shipping and some came missing. They will get the job done, but I highly recommend ordering extras.

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.
