Hi guys,
I'm working on pulsing a solenoid, not very fast, maybe at most 10 times a second. Right now the solenoid is a 12V continuous duty, 14 ohm coil, push type. I have a function generator to use for driving the signal but may implement a 555 timer later. I'm not sure which would be better for supplying the current to the solenoid, either a BJT or a MOSFET. The function generater can supply either TTL or CMOS level output.
For now I plan on using just a 50% duty cycle but am also wondering how the amount of on/off time could affect how fast the solenoid can pulse due to factors such as the build up and collapse of the field around the coil. If anyone could make some suggestions I would appreciate it.
Dave
