Electric solenoid experience

[aldaeron]

R29 allows:

Electrical solenoid actuators, no greater than 1 in. stroke and rated electrical input power no greater than 10 watts (W) continuous duty at 12 volts (VDC)

I am curious if anyone has used electrical solenoids and if there is one you would recommend? I see some on McMaster that explicitly list continuous wattage (part weight not listed) and some on Amazon that list weight but not explicit continuous wattage.

Will FIRST accept (continuous duty power) = (nominal voltage) * (max rated current) as an acceptable way to calculate this?

I could only find 1 recent thread on electrical solenoids (plenty for pneumatics), but no feedback on how well it worked. In particular I am curious if these would work for disengaging dog gears (not in a gearbox, and for short periods of time).

Thanks!
