6-3 Battery, RTC(Clock), Buzzer and Cash Drawer Circuits
6-3-4 Cash Drawer Driving Circuit
The circuit is used for opening cash drawer and driven by the Q1(MMBT222A),Q2(KSD288-Y). When its state is high
level signal, Q1(MMBT222A) or Q2(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 20
Ω
