Medium Push-Pull Solenoid - 5V
or 6V
PRODUCT ID: 3992
DESCRIPTION
Solenoids are basically electromagnets: they are made of a
big coil of copper wire with an armature (a slug of metal)
in the middle. When the coil is energized, the slug is pulled
into the center of the coil. This makes the solenoid able to
pull from one end, or push from the other.
This solenoid in particular is chunkier than our little 5V
one, with a 27mm long body, 10mm long throw, and a
'captive' armature with a return spring. This means that
when activated with up to 6VDC, the solenoid moves and
then the voltage is removed, it springs back to the original
position, which is quite handy. Many lower cost solenoids
are only push type or only pull type and may not have a
captive armature (it'll fall out!) or don't have a return
spring.
You'll need to power this here solenoid with
about 6VDC (you don't have to be exact, 5 to 6V will work
fine) and ka-pow, it's now a magnet. Turn off the power
and it reverts back to a normal chunk of metal. Since it's a
coil, you'll need to use a motor or solenoid driver with
kick-back protection. These draw quite a bit of current,
800mA at 5V and 1 Amp at 6V so you'll want a good strong
driver. Our Crickit boards will work well if you use a motor
port
