/technologies/test-and-measurement/b/blog/posts/the-danger-of-thermocouples-from-dodgy-sourcesDue to the current shortages of parts, and the escalating costs, I decided to skimp a little and buy a bunch of thermocouples from AliExpress, because I needed quite a few for testing a couple of projects.

I have plenty of thermocouples with that style of sheathing, stray fibres included ... some via e14&#39;s house-bands on clearance as well ... it&#39;s never been a major issue as I don&#39;t run my hand along the sheathing but they usually didn&#39;t claim to withstand very high temperatures either.</p> <p>I still prefer more plastic-coated ones, but the temperature range is more restrictive ...</p> <p>- Gough</p><img src="https://community.element14.com/aggbug?PostID=24255&AppID=13&AppType=Weblog&ContentType=0" width="1" height="1">
