Details
These are a miniature 'pull' solenoid, operate quite happily from 1.5v upto 6v, 100mA max.
Quite strong for the small useful size, they also have a magnet that retains the plunger once the voltage has been removed. By gently opening the coil frame it is possible to remove the 2 magnets leaving just a usual solenoid, it may also be possible to grind down a spacer at the back of the frame, increasing the stroke by a further 5mm.
The plunger has a stroke of about 8 or 9mm and is about 4mm in diameter, with a 5mm x 2mm slot engineered into the end, with a 1mm hole either side which is used for securing something in the slot.
Dimensions of the body are roughly 20mm long x 7mm high x 10mm wide.
There are 2 tapped mounting holes on the bottom that look to be about 2mm. Fitted with about 16cm wire.
