They're very usable at 5v, but the resistive screen I'm dealing with is finicky, so I've been using 12v. I only actuate for .15 seconds, so the thermals don't seem to be a problem. If you're looking for a video of them in action there are several on youtube. Mine is at https://www.youtube.com/watch?v=vd8mirOy3wQ.</p>

One for use on a wire rather than PCB, and that locks in some manner? I am trying to build a wiring harness which operates a number of these solenoids. [UPDATE: I found them on amazon. They come in pairs, which means I'll have a bunch of extra male cables, but alas...it's not so expensive that this matters very much]<p>This would be better if it were a rush type rather than pull, however, I can use the stub end to attach less than optimally.</p></p>

Alternatively, you can just cut the connector off and strip the wires. The JST PH is probably too small to stick jumper wire plugs in, but it works for larger connectors, so it might work. Plain, stripped wires of sufficiently small gauge would probably work, but they might fall out if you don't hold them in somehow.</p>

There’s not really a fix for it yet, but I found that if the plunger hits something just short of it’s full throw, it won’t get stuck. So they won’t really work for just playing with them, but they should work if you have them in some kind of setup and fine tune it so they never reach their full throw.<p>Also, I don't think diodes have any influence, cause I didn't have any diodes in my circuit.... I was just playing with it and a couple of AAs on my desk. If I had been actually using in an application, or if I hadn't been using alkaline, I would have used diodes and everything.</p></p>

The front part of the plunger(the rod running through the center) shoots out, but at the same time, the back part(with the spring) is pulled in. So to pull something, you would just have to attach it to the back of the plunger instead of the front.</p>

I got one a couple months ago and when you apply voltage it activates fine, but sometimes when you take it away the plunger will stay forward. When I first got it I thought "Oh, well it's probably just because it's new." except now it happens more often than not and I can't use it. To reset it I just have to press lightly on the front of the plunger, then it snaps back the way it should. I don't think it's magnetism, because it doesn't matter what polarity I use. Also, interestingly, it never gets stuck forwards if I push it forward manually, only when I power it on. Did I just get a bad one?</p>

If you decide to use a 9v powersupply, you go get an LM7805 with good cooling (4W of heat is A LOT). Alternatively, you get a better chip, that can do the 9v->5v conversion more efficiently.<p>Alternatively, and what I would recommend, you get a 5v 2A power supply, feed the arduino 5v on any 5v pin in the header, and feed the solenoid 5v directly from the power supply. then control the solenoid with either a relay or a transistor.</p></p>

If they draw up to 1 amp at 5 volts that's probably pushing it for the Arduino's 5V regulator output. So it would make sense to use a separate connection to the power supply with the Arduino controlling a transistor or relay. But if you're using an external power supply for the Arduino, it's probably 9 to 12 V which is probably too much for 5 V solenoids. So how do these facilitate working with an Arduino? Is the idea to use a 5 V regulated supply for the Adrunio (USB power input? bypass the regulator?) , that is also capable of delivering enough amps to power the solenoid in parallel?</p>

That way you don't have to monkey around with electronics. The relays from SainSmart don't require any special wiring and can be powered from an arduino or RaspberryPi. If you're just using the solenoids for a quick on/off you can wire the solenoid through the relay to the power source without any other wiring. If the solenoid is going to be "on" for a while you will probably need a resistor in line to dissipate some the power. You can probably find a relay board (e.g. SainSmart) that can control 8 things for under $10. The problem is that a relay makes a small click sound, but a solenoid does as well. If you listen to the video below, you can here the relays/solenoids in the background. I'm currently using the Sparkfun 5V relays for a music projects, they're pretty small but work quite well. "Push" type solenoids are often easier to use for music stuff.<p>Here is a project I did using a RaspberryPi, relay board, solenoids and a Korg Koass Pad. This would work just the same with an Arduino. I've used various solenoids as percussion sources, they work very well.</p><p><a href="http://www.flickr.com/photos/51276066@N00/8687914022/" rel="nofollow">Picture: RaspberryPi->Relay->Solenoid->KorgKaossPad</a></p><p><a href="http://www.youtube.com/watch?v=Ew50g8RKoR8" rel="nofollow">youtube video of above project</a></p><p>If you want to get really simple, scrap the arduino and get a doepfer midi to gate, then you can get a usb to midi and camera connection kit and run the whole thing from your iPad! No software to write, just midi (you can sequence your solenoids using Ableton Live or MaxMsp.

I don't need it to be very powerful, but I'm planning on using one of the 3v laser cards in the same project and I can't find a 3v limiter. Also, a pull-type version of this would be appreciated.</p>

Question: Would this be able to be driven from batteries? I can get the voltage close enough, but I'm concerned that batteries won't be ablt to provide enough current. It only has to unlatch once, for just a few seconds.</p>

When not powered, the spring causes the end to slide back into the solenoid. I just spend two hours playing with these things, so fun B-)</p>

The 20ms works great, and if you want the most vibration out of these make sure the plunger that pushes out hits the wall of the enclosure to really add some vibration force.<p>Also a side note, a bi directional motor driver does not work, if you reverse the polarity on these it does not cause the plunger to go the opposite direction like you might think. If you apply current any direction, the solenoid pushes out. I was surprised and originally tested this with my h-bridge IC. If you want the plunger to return, you must leave the spring in place. Luckily the spring is soft and just strong enough to push the arm back and doesn't seem to effect the vibration much.</p><p>Solenoid rail gun..... I like the way you think :-)</p></p>

I hooked the solenoid strait up to my 5v dc power supply and both drew approximately 1A.<p>They take about 15 to 20 seconds to heat up when continually on, so 15 second cooldowns should be fine if you are not pulsing them.</p><p>I think your math looks sound B-)</p></p>

If this is a 1.2W device with 4.5ohm coil resistance then you only need 2.32V to actuate which is a far cry from 5V. Not to mention the lowest voltage specified on the datasheet is 3V @ 7.5ohm</p>

One thing I notice, how do you attach something to the end of it? For example, if I want to have this move a gear mechanism, how would I attach the push arm to the rest of the system? Or are these designed to push something without actually being attached to it?</p>

I=P/V = 1.2W/5V = 0.24A, or 240mA.<p>Now, the part number, according to the data sheet, means this is a <em>5V, push-type, 4.5ohm solenoid</em></p><p>Assuming no reactance and only resistance (fair using DC without PWM)...
V=IR
I = V/R = 5/4.5 = ~1.11A or ~1110mA</p><p>This is higher than the 240mA max continuous rating. So I'm not sure what to do :p</p><p>That would give (1.11A * 5V) = ~5.5W. According to the datasheet, this should then be powered using PWM with <em>less than</em> 25% duty cycle @5V or use full 5V (100% duty cycle, essentially no PWM) for no more than 15 seconds at a time without sufficient cooling (@20 degrees C or 68F).</p><p>You could also put a resistor in front, so you can use for continuous use. I recommend 20ohm, 2W resistor, or higher resistance with a 1W resistor.
You can make a 24ohm, 1.25W resistor by placing 5 of 120ohm resistors in parallel. Then it's a simple matter of placing that in series with the solenoid as if it was one resistor :)</p><p><em>Someone please check my work. I am no expert, and the information above may be flawed!</em></p></p>

Fun to use as a mini coil gun when applying way too much DC voltage ;)<p>Or, hook up an AC adapter to it (24V heated up my 12V one very quickly, beware) and use it as a strong linear vibrator or buzzer. You might be able to simulate that with a motor driver simply, by changing the "direction" rapidly (50Hz may be a good test, so 20ms per pulse in a direction). The spring on this one will probably dampen the effect a lot, but it can be removed if you don't mind taking it off. :)</p></p>
