4-3-3 Cash Drawer Circuits
The circuit is used for opening cash drawer and driven by the Q8 (STA471). When its state is high level
signal, Q8 (STA471) 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. ※
