Great vid! wondering can you operate one solenoid at different amounts of current in one circuit? I'm guessing this would be done by some parrell circuit of some sort, or a diff. load voltage?
The solenoid is rated for 12 volts; at higher voltages, you might fry it, and at lower voltages, it might not move at all. Why would you want to operate a solenoid at different amounts of current anyway?
so if the power is on all the time the solenoid would be out yes then when power is cut off it springs back. can you keep a contants 12v feed to it without it blowing up 12v mine is i want to know if the 12v in is present for lets say 3hrs or so would it be ok
It can push with about 0.4 N of force. You're going to need to measure how much force your can needs. A servo motor may work better if you need more force.
A solenoid is an inductor, which means that it draws very little current at first and then gradually draws more current. That said, real solenoids have some resistance. This one did not draw more than 4 amps while I was using it.
hi thank you for this awesome video. can you please guide me to use what kind of solenoid and battery with volts and other specs that can produce 50N and 100N of force.
+Be Like Bill Solenoids have two difference force ratings. The force that is usually listed is the holing force, which refers to the amount of force that you would have to exert in order to pull the plunger in the reverse direction when the solenoid is powered. (In fact, I just realized that the video description is a little ambiguous. I'll update it.) The force that the solenoid can exert on another object is usually much less than the holding force; in this case, it was less than 1N. If you need to exert 50N to 100N of force on another object, consider using a pneumatic piston instead.
Hi Dave I’m look at building something using basically the same solenoid and a PIR. So I have a micro PIR sensor that momentarily switches on and off for around 2-5secs running off a CR2 battery 🔋 what do I need in between the PIR & solenoid? I.e diode and also need a current limit of 100ma. If you can help me out
I assume that you can make the PIR and solenoid share a ground. You'll want an N-channel MOSFET. It can take a low-voltage, low-current signal and switch a high-voltage, high-current line on and off. Look at "Simple Solenoid Drivers" on www.electronicdesign.com/industrial-automation/what-s-best-way-drive-solenoid for the basic idea.
how fast is can this actuate? planning a 3d printed paintball marker, and trying to come up with ways to get something to actuate the ball valve letting air to escape and send the paintball flying. I am trying to get to atleast 5 balls a second if that info helps.
In this video, the plunger takes about 2 frames to move its full range. At 30 FPS, that is about 0.067 seconds. I would probably need a high-speed camera to get a more precise measurement.
Hello David. I’m building a possum trap. Cage type. As a kid I made traps where a possums weight on a ramp tripped a guillotine type trap door that shut behind animal. Now I want a electric trip where I still use a ramp which taps a micro switch that sparks the coil/solenoid pulls the pin that drops the door. But how do I stop power after trap has tripped? Power would have to be switched off to avoid burning out coil.
You're looking for a monostable multivibrator. Here's a version that doesn't use a 555 chip: www.falstad.com/circuit/e-multivib-mono.html Here's one that does: www.falstad.com/circuit/e-555monostable.html
@@wecsam Thanks for the reply... I will just use another Micro switch! First one (N/O) will be on the platform and trigger the Solenoid. and gate drops The second Micro switch (N/O) on a roller arm will be on the dropping door and when the door has dropped the door will run off the switch and will "open" the circuit. Therefore cutting power to coil.
After the current stabilizes, the solenoid draws about 4 amps. It does get hot, but I do not know whether it would fry. Perhaps that could be its own video.
+kawi21 The solenoid is an inductor, which means that the current cannot immediately flow at its maximum. When an inductor is discharged, it's like an open circuit. When it is charged, it is like a short circuit. The solenoid's magnetic field, therefore, won't be at full strength until the inductor is fully charged and the current is flowing at its maximum.
That's going to depend on the switch and the solenoid. The solenoid in the video was not able to push or pull with much force; it is not strong enough to push any switches that I've used. You would have to make sure that your solenoid is strong enough to push your switch. It might be easier just to use a servo motor; some of those have a lot of torque, and there are plenty of designs on the Internet that mount servo motors to light switches. I have a video where I show just that: ua-cam.com/video/m3pA422aRlg/v-deo.html
Not the one in the video. The force that is required will vary (different surfaces will have different amounts of friction, for example), but even in ideal conditions, the solenoid that I used won't push a whole tennis ball that high.
@@raymetal7 More like 1.3 cm in ideal circumstances. I previously measured the solenoid to push with at most 0.50 N. Let's assume that it exerts this force constantly while the plunger is moving, and let's assume that the ball stays in contact for the maximum travel of 0.010 m. That's 0.0050 J of work (force * distance). Convert that to gravitational potential energy (mass * gravitational acceleration * height). A standard tennis ball weighs at least 0.057 kg. Assuming 9.8 m/s^2 acceleration of gravity, if we solve for the height, that gives us 0.0090 m of height ([0.0050 J]/[9.8 m/s^2]/[0.057 kg] = 0.0090 m). Of course, that's going straight up; if the ball is rolling up a 45° ramp, then we can divide that by sin(45°) to get 0.013 m or 1.3 cm. Again, this is assuming no friction, a constant force from the solenoid, and contact between the ball and the plunger for the plunger's full range of travel. Of course, if you got a stronger solenoid, then the ball would move farther.
@@raymetal7 Oh, and this assumes that the ball doesn't roll. We already assumed no friction, so the ball won't roll as long as the force is applied perfectly in line with the ball's center of gravity.
For something as heavy as a tennis ball, you'll probably have a much easier time with a pneumatic piston. These small solenoids can't produce a lot of moving force.

You could add a heatsink to the diode, but if it's getting too hot, double-check that you're using the correct voltage for it. Check that it is drawing the amount of power that the manufacturer specified. You could also try another solenoid in case that you have a defective one. I don't have the exact diode model anymore, but any 1N4*** should work. It only has to block Vcc.
You need to make all your grounds are connected. This normally happens when people are using external power and something like an arduino but have not connected the grounds together. Also listen to David. Make sure your power supply is supplying 12V AND the current needed by the solenoid.
I'm looking at these to activate a pull pin on a rc 1/10 winch can I just hook up the positive to a switch turn on stays pulled in until switch is turned off then springs back then opersite way wind winch in 🤔
Yes, the plunger stays pulled while power is on, and a spring pushes it back when the power is cut. A switch would work great for controlling this. However, just be aware that it doesn't pull with much force; I am not sure how much force your pull pin needs, but you might need a bigger solenoid.

It can push with about 0.4 N of force. How much weight that translates to depends on how you're using the solenoid. If you're pushing horizontally across a surface, you'll need to know the coefficient of friction between the object that's being pushed and the surface.
