Coin Acceptor - Programmable 4 Coin Type
This interestingly fun product is created in a way that accepts 4 different coins! From different countries!
All you need to do is to program it with your choice. Note that any coin from 15mm to 29mm in diameter can be used!
In general, these coins chosen will each be having a number of pulses that make it distinguished from each other. When a valid coin is inserted, the output line will pulse for 20-60ms (configurable). In case a valid coin is inserted, this product will start looking for diameter, thickness, dropping speed, and things like that.
The following things are all provided:
• Acceptor itself
• Mounting hardware
• Cable for power/signal
