7-3-3 Cash Drawer Driving Circuit
The circuit is used for opening cash drawer and driven by the Q4(KSC945-G),Q3(KSD288-Y). When its state is high
level signal, Q4(KSC945-G) or Q3 (KSD288-Y) drive the solenoid to open the cash drawer. As an optional item, we
provide sensor switch (we call it a compulsory switch) which checks the drawer whether it is opened or not. This sensor
switch turns on for the drawer open condition, and turns off for the other.
Caution: Make sure that the Cash Drawer solenoid resistance is more than 20Ω
