4.5. Coin
Sizes
The C120S accepts the following range of coin or token dimensions which is believed to
cover at least 95% of the world's coinage :
Table 4: Coin Sizes
Diameter:
15.0 - 33.0 mm
Thickness:
1.2 - 3.3 mm
Weight:
1.5 grams min.
The coin or token material may be any of the normal alloys that are generally used to
produce coins world wide. Coins may have holes or be non circular providing that they are
capable of rolling uniformly down a ramp at an angle of 15
°
to the horizontal. Tokens may
have identification grooves.
4.6. Wet Coin Handling
The C120S acceptance rates and coin throughput may be degraded where there is
condensation on the rundown. Any coins, which may become stuck in the rundown due to
moisture can be ejected by activating the coin reject mechanism. Furthermore, the rundown
is profiled with grooves, which reduce the surface tension on the coin, ultimately reducing the
sticking potential of individual wet coins.
