Solenoids are a great way to induce linear motion for pushing, pulling or controlling switches and levers. This smaller solenoid is designed to work directly with 5V which makes it a great match for embedded projects. It has a throw of about 4.5mm and 2 M2 mounting holes on the body.
The wire lead is about 2" long and is terminated with a 2-pin JST PH connector.
Note: The mounting holes on this solenoid are actually 1.6mm in diameter. This will allow you to tap for an M2 screw. Also, although the datasheet lists a throw of 6mm, the actual throw appears to be closer to 4.5mm.
At 5V, this solenoid can pull up to 700mA of current. In order to control this device using Arduino, you will need a MOSFET. We recommend using our MOSFET Kit to safely control this product.
To control the solenoid from a microcontroller, you'll need to add a flyback diode and a MOSFET/Relay. For more information, check out the application circuit in our diodes tutorial. The solenoid will simply be added as a load on the MOSFET or relay of your choice.
This skill concerns mechanical and robotics knowledge. You may need to know how mechanical parts interact, how motors work, or how to use motor drivers and controllers.
Skill Level: Noob - You will be required to put together a robotics kit. Necessary parts are included and steps will be easy to follow. You also might encounter basic robotics components like bearings, mounts, or other hardware and need a general idea of how it goes together.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Noob - You don't need to reference a datasheet, but you will need to know basic power requirements.

I used these for my Robotic Glockenspiel project, as the hammers that hit the chimes. They seemed to need 9V (rather than 5V) to operate well, but I'm careful to keep the power dissipation below the rating in the specifications. I removed the snap ring and spring to reduce the noise of operation - letting gravity bring the slug back down after hitting the chime.
I like these solenoids because I can run them from the Arduino 9V Vin (with a 1000uF cap to avoid drawing the power supply down). I use a TIP 120 transistor to control the power to the solenoid.
A few wishes to make it even better for me: tap the holes rather than leaving them untapped, and don't go to the trouble of adding a connector to the solenoid wires.
These have turned out to be nice, inexpensive hobby solenoids I can easily play with. I like them a lot.

If you give this guy 12v quickly, it's got a great punch to it.

I bought this solenoid as part of an engineering design lab at Drexel University. It works exactly as we hoped and I'm so excited for the end result of the project!

I used one to tap on a wooden birdhouse, simulating a woodpecker pecking on a tree. I glued it down and wired it in place. I ordered 2 more for future projects. Note - It is a push type...NOT a pull . You can see it working here - https://youtu.be/yhX_9fFmt0Y

it does not have a force of 8 ounces as was indicated. misled just for a sale--bad business or you don't know what u r selling
Hi, Specs are stated by the manufacture. We have not tested them in house against the rated spec, however I have heard that these can be below that indicated 8 ounce force. So sorry for the confusion.
we used the solenoid in a science project to pop open doors and it worked wonderfully.
It worked well for me. in raspberry they can work in 3v as well.. very good material and well done connector..
works well but I lost the spring and the E clip. My bad, I'll need to improvise

Needed a pull solenoid; there's no way to convert this from a push solenoid to a pull solenoid. (There isn't enough metal extending beyond the C-clip to attach something.)
Didn't work, don't know I'd it was defective or not. Most items I have bought from Sparkfun have been of pretty good quality.
So sorry it didn't work. If you would like to contact us about a replacement check out https://www.sparkfun.com/returns
small but powerful when you use a 12v source
If anyone is interested, I measured a series resistance of 5.1Ω and inductance of 2359.25µF.
It was much smaller than I thought and throw to short so I couldn't use it in my project
Give me a little more time, please. Maybe I can send you a video?
And I mean that literally. I'm driving a 9v pulse to the solenoid to give it some extra kick and it's working wonderfully!
It's very well built, and works without a hitch. I'm using it in a wireless bell ringer system, and I couldn't ask for anything more.
Good solenoid surprisung for size.Only critique would be to leave the force stroke and newtons of solenoid. Unless you are an electrical engineer and can calulate electromagnetic force you are going to have a tough time figuring this out.
Ok, I found by just applying 5v to this solenoid gives little effect. In my application it trips a spring loaded trigger for a retractable handheld device. I was only able to activate my trigger about 50% of the time. So I changed my power source to 9v and employed a charge-pump circuit to step-up the voltage to 18V. I also used a 24v 470uf capacitor to store the charge and a IRFD110 mosfet is place of my mechanical relay to accept the 5v trigger voltage from the micro. NOW... with all of this the solenoid triggers my project perfectly every time. I am only allowing the mosfet to apply 18v for about 25ms to the solenoid so no internal damage occurs. See my DropBox link below for schematic.
Yes, these are tiny, somewhat weak, solenoids, but they draw only about an amp at 5V, and only support about an 8gf, so you really shouldn't be surprised if they can't unlatch something with lots-o-friction or lift heavy items.
I used these for ringing a bells in an electronic Grande Sonnerie project. The key for bell ringing is both the placement and "on" duration. The kick from 5V is more than enough to ring a small French brass clock bell (~1-2" in diameter). The best performance was achieved by keeping the duration short (5ms or so) and placing at just the right distance.
Snaps well with 5V but the throw is only 4mm. I agree with other comments that the manufacturer shouldn't bother with the connector--just leave bare wires. Also, since the holes aren't tapped, maybe sparkfun could upsell customers by having a link to a tapping kit.
Just what I was looking for my project.
I needed a kicking mechanism for the soccer bot I'm building. It had to be small and require only 5 volts, but still be able to propel a ping pong ball several feet. I wasn't sure if this solenoid would do the job, but it turned out that it was just what I needed. The coil draws almost an amp of current (I use three AAA batteries which drops from 6 volts to 5 volts when current is flowing), so it gets quite hot, so you probably shouldn't activate it for more than a second or so. There's a smaller plunger on the other side of the one with the spring which is pulled in by default, so I have my microprocessor send a pulse of a fraction of a second so that it quickly extends and is pulled back by the spring, sending the ping pong ball on its way.
