Does anyone know of (or has used) a small, fast pull-type solenoid? By fast, I mean the pin is drawn in (0.5") in <10mS.
I'm currently using
Guardian Linear Solenoid-The Electronic Goldmine
which at 36v (max rating of solenoid is unknown) draws in fully in about 20mS. Not too bad, but I'd like something even faster, <10mS. At 24v is takes about 30mS. Extrapolating to 48v presumably gives a time of 10-15mS, assuming inductive effects etc. don't hamper things terribly. I'm reluctant to go to these high voltages, because of my general lack of experience.
in case you're wondering, I'm using the solenoid to open an external camera shutter so I can photograph flying insects. Inspired by this chap,

I'd also be interested in any other fast actuators that can pull a lever really quickly, over a linear distance of 0.5"
I also wonder if a smaller solenoid would be faster, because the inertia of the pin is smaller...
Many thanks.
