Replacement: COM-11719. This coin acceptor unit has been discontinued, but we have a slightly spiffier 3-coin version. This page is for reference only.
Description: Are you trying to make a quick dime from electronics? Why limit yourself to dimes? This coin acceptor will take two different kinds of coin! Whether you're building your own arcade cabinet or just charging admission to your house, this programmable coin acceptor makes it easy to monetize your next project.
The sensors in this coin acceptor use the thickness, diameter and fall time of the coins to identify them and it's fully programmable so you're not limited to any particular type of currency. Simply use the SET button and LEDs on the side of the unit to enter programming mode, insert a bunch of coin samples (or the same one, over and over) and you're good to go! After you've programmed the coin profiles, the coin acceptor will recognize them and report when each type is inserted, rejecting other coins.
This coin acceptor also has a coin inhibitor, so your controller can tell the coin acceptor not to take any more coins. All you need to get the coin acceptor working is a pocket full of change, a 12VDC supply and somewhere for the change to fall after it's accepted.
So maybe you won't get rich building your own vending machines but access control using different sizes of tokens might be cool, or even a virtual vending machine where you can buy MMORPG items. There are a ton of cool coin-operated projects just waiting to be built!
