So c4242 transistor datasheet my math is right, the two transistors should saturate and activate the solenoid when the two resistors in my circuit diagram above are less than or equal to 3.

From what I’ve been reading, 0.

My power source is 24v, so I really just need to design a “switch” circuit to activate the solenoid when the laser beam is broken. I c4242 transistor datasheet a solenoid that takes 24v to activate, and I want it to activate when a laser beam from a laser pointer is broken. So, I decided to give the Darlington Pair ddatasheet try Choosing the Right Transistor: The solenoid uses mA c4242 transistor datasheet the c4242 transistor datasheet current of the transistor must be about 50mA for it to turn on completely.

Last night, I took apart an old ATX power supply discharging the caps properly first! In a darlington transistor the output transistor has a high collector current and a high saturation voltage.

Apr 7, 4. I’ve really learned a lot!

f4242 However, I’m having some trouble Posted by Celler1 in forum: I was going to try using an LM dual voltage comparator since I happened to have one on handas suggested in the link provided by mik3, but it looks like won’t handle the mA 24V that c4242 transistor datasheet solenoid draws.

Photocell “switch” help

I’ve searched the forums and Google, but I haven’t really come across what I need. I’m scared to play with the 10k variable resistor too much, since I’ve only got a few of these 2NA transistors and I’ve already managed to fry one.

Photocell Switch datqsheet or 12v DC Posted by truwebs in forum: Thanks again for all of your help. Apr 10, May 16, 5, 8. Apr 9, 8.

Thanks transisyor for the c4242 transistor datasheet replies, guys. I can see it move a little, but it never fully engages. C4242 transistor datasheet 9, 9. The solenoid is very quick c4242 transistor datasheet respond when the laser beam is broken, so it looks like we have a winner here!

C4242 transistor datasheet 8, 5. Can any of you help c4242 transistor datasheet out? Apr 6, 3. Your solenoid could be put in place of the LED and it’s resistor, if your op-amp can sink enough current to close your transisor.

Posted by alquimista in forum: Does this look right to you guys? But then the LDR will fry when it is in the light. That really helps a lot, guys.

My second problem is that the transistor starts to get very hot after I connect the 24V source to the circuit. Aug 8, When the laser beam is interrupted, the light on the CSD will go from “bright” to “dark.

So, I decided to use c4242 transistor datasheet 2NA transistor datasheet instead, since it can handle up to mA. Feb 15, 15 0. Maybe point me towards a schematic that you already know of?

Apr 8, 6. Your name or email address: Another option would be to drive the 2N with the C4242 transistor datasheet Photocell “switch” help Reply to Transisor. The input transistor has a low collector current and a low saturation voltage.

Dec 20, 10, 1, Yes, my password is: Apr 6, 1. Apr 6, 2. Here is the circuit that I’m using.

Another way to do this would be biasing a transistor with the voltage divider.
