Just wanting to double check something, and hopefully learn something new as well.
I’m working on a circuit to control my paintball marker, and I’m almost at the point of testing. What I wanted to know is do I need to have any extra protection from the 9V solenoid on my circuit, or is that the whole point of the diode?
The circuit itself consists of 2 solenoids - one for the sear (9V and around 4 amps) and the other is for redirecting the flow of air to the cocking pneumatics (rated 6V but will drive at 5V and 0.5W - I have found the data sheetSolenoid_Valve/1.1)4_5_Port_Solenoid_V/c)SYJ3000_5000_7000/SYJ_000_EU.pdf) for this part) and a phototransistor eye (datasheet)
The sear solenoid would be on for a max. 4 ms, while the cocking solenoid could be on for as long as the trigger is held down (this is to replicate the current functionality). Is there anything I should be worried about? Should I drive all the solenoids at the same voltage? Am I just over thinking all this?
Any helpful pages or topics that I can look into and expand my knowledge would be awesome, and thanks in advance for the help
