This coin acceptor will accept as many as six distinct coin types! The thickness, diameter, and fall time of the coins are used by the sensors in this coin acceptor to identify them, and it is entirely customizable so you are not restricted to any certain sort of currency.
By analyzing the coin's mass, size, diameter, thickness, metal composition, and/or magnetism, the coin selector determines which coin it is, and after that, sends the proper electrical signal via its output link.
It also contains a coin reject button that your controller may use to instruct it to stop accepting coins.
A pocket full of change, a 12 VDC supply, and a place for the change to fall once it is accepted are all you need to get the coin acceptor running. It can be easily interfaced with any sensors.
