This component was pulled from a device that was used to detect movement. When I first saw this part, I thought it was an electrolytic capacitor, but upon closer inspection, I found that if I shake the part, it has a small metal weight in the end (opposite of the two wires) that rotates around. I'm guessing it is some kind of mechanical motion sensor, but I'm not sure what the technical name is. I'm interested in finding its datasheet or a similar part to use for another project.

\$\begingroup\$ Then yeah, as said, it's a tilt sensor/switch. Something similar to this: chipmall.com/product/comus-international/pd6010/5998876 \$\endgroup\$– Eugene Sh.Sep 14, 2018 at 14:26

1\$\begingroup\$ I know the text in the op leads us to this conclusion, but doesn't it look more like a vibration motor? \$\endgroup\$– evildemonicSep 14, 2018 at 14:47

It looks like a vibration motor. A small electric motor with an unbalanced weight on the end of the shaft. Apply a small voltage and it should spin and vibrate.
Looks a lot like this one.

4\$\begingroup\$ So, Jason, how do you explain your first statement, "This component was pulled from a device that was used to detect movement."? I'm just wondering what sent you off on the wrong track? \$\endgroup\$ Sep 14, 2018 at 15:26

3\$\begingroup\$ For one it looks like a canned tilt sensor... \$\endgroup\$– PasserbySep 14, 2018 at 16:03

1\$\begingroup\$ @Transistor it's still possible that the larger device this was pulled from detects movement. And apparently also vibrates sometimes (though that seems a little self-defeating). \$\endgroup\$– mbrigSep 14, 2018 at 17:22

2\$\begingroup\$ @mbrig: Of course, but what was this thing? And what was the thought process? \$\endgroup\$ Sep 14, 2018 at 17:26
