cpc1017 i use a lot , it is activated with 1ma in its led so a 10kohm resistor in series will fully activate it
dependict what and how you want to activate a simple PC817 could also work but almost certain will need to drive a transistor in its output
yes but NOT looking for pot resistor value, this can be calculated
looking a a pot (model) that can stand/hold 1-2-5 AMP through it, at 0.2ohm (almost turn off) value
for example this CAN NOT hold that current -> https://sc04.alicdn.com/kf/HTB1Nesty_lYBeNjSszc762whFXai.png
i am looking for...
yes this is the schematic of the datasheet
however what potensiometer can be used that will hold 1A at 2ohm !?
alternative question can suggest some other regulator (linear) with minnimun part needed for current limiting ?
Hello
in lm317 etc, there are schematic that shows using a potentiometer for output can used for current regulator applications
however potentiometers at the minimum output (i.e 1ohm) can NOT hold current at 1A or more ..
is there potentiometers able to drive 1/2/5Amps ?
or any other idea for...
I have program the mcu, and it DOES reports its ID, but never returns temperature
i am wondering what the article (Attached file) says about INT, google translate does not help
or if anyone have build use it ?!
the desing of these products are by definition medium security
"high" security product has Central unit's installed inside building (in a secure are)
OUT OF TOPIC how does this magnet with lever/stick called ?
here i created a video showing how it is work , i dont think that with negative voltage has ANY difference in magnet power compared to when NOT APLYING voltage AT ALL
https://youtu.be/gc7G8Jlxco4
but shouldn't ,after the pulse aplied and the plunger returned to inner position a force strong enough hold it ?
what i mean is that if is holded with a force of 100gram (for example) without applying any power to coil, when applying negaltive polarity this force must SIGNIFICANT reduced ? ...

and https://www.electro-tech-online.com/custompdfs/2013/02/3884.pdf
after significant testing...
if i manually pull out plunger , correct voltage brings it back and hold it , strong enough, however aplying reversed polarity...
i have finaly get a few from farnell (even small) but i can t get them work.
i apply 12 volt in cables nothing moves , i aply reversed current nothing again.
power consumption is according to datasheets 200+mA
thanx for reply firstly
@ericgibbs your first suggestion is the exact model i said wich i believe is has small diameter plunger (7mm)
second one has the same diameter plunger too..
@Pommie i cant see the plunger there, neitehr it looks like latching (is it ?)
Hello
i am looking for latching type solenoid with relative big "moving object" (dont know how its called the stick that moves)
i would like diameter of this to be at least 1cm , and preferable from a seller in European Union, 12volt coil is the ideal but smaller rated are good too
i have...
