It is definitely an US part.
My local store here thought it was a 5/32 and I believed them. Might even be a #7 as you say. I probably need to measure it myself....
With respect to the list in my first post, does 2-56 then mean screw #2 with 56 threads per inch? and "4-40" is #4...
I am currently trying to buy some imperial machine screws and bolts online, and I am confused with how the diameter is given.
The website I am seaching (boltdepot.com) gives me these diameters but I don´t understand what is meant by i.e. "2-56"
Thanks again, uart...it becomes clearer but not 100%.. I need to read some more before I ask again ... :-)
Another thing... with reference to my circuit in post #5, if there is a connection between any point on the secondary side of the circuit and Protective Earth, does the isolation...
Thanks uart, but still one thing is unclear to me...
If there is a connection at point A (in my previous drawing) wouldn´t there be a difference in potential between the metal enclosure and Protective Earth?
Thanks...but then I have more questions...
With reference to the diagram I have attached, there is accidentally a connection at point "A" making the "guy" touch a wire or enclosure that is conductive.
Does the fact that the secondary part of the isolation transformer not beeing connected...
An isolation transformer is used in order to "safely" separate one part of an electric circuit from the mains. (description in http://en.wikipedia.org/wiki/Isolation_transformer" [Broken])
Still I have problems grasping the important concept of such a transformer. I have spent some...
Thanks for the tips and links.
...and yes, I meant 8kV (not 8000kv).
The pdf you (berkman) linked was interesting, but due to tight time frames right now I have changed the switch for one with a higher rating. Hopefully it will work.
I have a switch connected to a motherboard.
During ESD test with 8000kV (directly on the switch) the ESD spike caused my system to reboot, and I need some kind of surge protection betwee nthe switch and motherboard.
I am not sure what I need to look for?
Can anyone suggest a...
I remember Texas Instruments had some good application notes on ECG amplifiers.
there are also plenty of books on the market. The "Webster" book as well as the one from "Enderle" (search for them at Amazon) are part of almost any biomedical engeneering course. They are good, but very...
I would like to build my own ECG monitor.
Does anyone have experience building one?
Especially I am looking for recommendations on which op amps I can use. The ones I have found, like TI's ina122, ina 332 are both rather expensive (like 10 euro per piece) and hard tu find...
