locating a push solenoid

I'm looking for a low-voltage push-shaft solenoid that I can drive
from a BS2. Duty cycle of 5-10%, shaft travel of .25 inch, shaft
force of 4 oz., ambient operating temp. of 10-80 degrees F..

Can someone point me to a reputable manufacturer?

Thanks!

    Check out Allelectronics.com or their catalog - they usually have some
    stuff like that

    reverse it mechanically - add a lever

    add extension to rod to either go all the way through the solenoid or around
    the coil

    maybe using a permanent magnet core ? and bias it with the coil ?

    I believe they always "suck in" - you have to do other things to make them
    push

    Look under the tubular solenoids and then look for push-type you
    will need a transistor to drive these or a uln or unl2003, you
    can order different voltages, force, travel distance and duty
    cycles.

    You either a push or pull solenoid that will do the job. The question is do
    you want continuos duty or not ?

    Not exactly "push"... more like "overshoot"

    Heck! Why not a speaker? 1/4 inch travel 4 Oz shouldn't be to difficult.

    That's a great Idea, If you need more travel just hit it with a
    couple thousand watts, one time use only.

    I was at www.tannerelectronics.com recently and they had a box of push
    solenoids on the shelf there. It looked like they had about 1/4" of travel
    to them. But you'll need a driver transistor for them or something like a
    ULN2003 driver. All the solenoids that I have seen can't be driven by any
    MCU directly. Either a transistor or a small reed switch is used.

    I have made PUSH solenoids by using a cylindrical
    magnet as a plunger, not quite centered in the
    solenoid coil. My application was a chime striking
    mechanism.

    Usually, when I think doorbell, I think of the classic DING which is the bottom
    strike plate and the DONG which is the top strike plate. The solenoid is
    energized
    causing the striker to overshoot and hit the DING, where upon release of the
    doorbell button, the striker is spring loaded back and strikes the DONG. [noparse]:o[/noparse])

    Your method of using a magnet is essentially the same physics of a speaker I
    mentioned earlier. With the addition of a magnet in the core of the
    "solenoid".
    you now have the capability of push and pull depending on the polarity you
    apply.

    Of course I had a spring return also, and the ballistic
    motion of the magnet (with a plastic "striker" attached
    caused it to overshoot and strike the chime just once
    per actuation.

    AFAIK the classic doorbell chime uses 24VAC, and the
    "push" motion is really "pulling" the core into the
    solenoid, with the extension sticking out the front end
    and striking the chime.
