Small thermodiscs anywhere?

Yep. Cheap is as cheap does :-) ...Jim Thompson

Actually, Foxit has never crashed hard. Adobe croaked several times a day. If companies make their web sites IE-centric or Adobe-centric, well, too bad, that's going to cost them sales.

Thermik ?

Last sample I had got was Priced at $8, for the S01 type. 9mm dia.

Farnell lists a couple of Airpax ranges of parts that seem to be reasonably compact - one lot in a TO-220 package and another in a short dual-in-line package. Life-time about 100,000 cycles at the low current that you want to switch.

Still a tad large but maybe it works. Thanks, Martin.

Thanks, Bill. I'll check out their TO220 offerings, a mounting hole is a big plus. Many others don't have that, for whatever reason.

Bill can you give me more of a hint. (part number ?) When I searched Farnell for Airpax parts I found a bunch of thermal stuff but no TO-220 or dual in line packages. Both may be appealing.

Thanks, George H.

Airpax and Cantherm have TO-220 style, and Airpax even has DIP-8. All should be < $10 even one-off.

Try Digikey..

It's this one Bill pointed out:

Thanks, Spehro, this one sure looks nice and Digikey has them:

thermodisc.com?

No

That's nice thanks!

That's where I looked first but only found the big ones like in my link. Same kind we have in our pellet stove :-)

The TO220 devices Bill pointed out and the Cantherm ones Spehro mentioned could fit the bill. If we can squish them in there. Else we'll just do it electronically, or have to.

That looks like a Klixon, but I don't know if they come any smaller or cheaper than that one. )-;

Good Luck! Rich

I have to rush out the door to a job site, but I have the perfect solution for you... I'll have to dig up the info on it, but we used 1000's of them on a prior project. It's a little cylinder (maybe 1/2" tall, roughly 1/4" diameter) with two leads on it. It takes no power, and provides a Form-A contact with decent hysteresis.

And inexpensive too. IIRC

Would that work? If not, I won't bother racking my brain this afternoon trying to recall who made them. But for what we were doing at the time, they were the perfect solution. Also, what temperature range do you require?

Used keyword klixon and found:

Look through their stuff and see if anything strikes your fancy.

Good luck. John

Cool Thanks... These look nice, I wish they would list the price!

The Mil-spec sounds like $$.

Thank you, but we may already have an electronic solution now, or one or the Airpax or Cantherm devices. It is important that it has a mounting tab so can be bolted to the surface that gets hot.

They do look nice, although not as easily mountable as the TO220.
