Optical coin switches?

RayB:
I just bought a lot of single-chute coin acceptors and one of them actually has a sort of optical coin detector instead of a switch with trip-wire. I've never seen this before. Are they reliable? Obviously they need to be powered... (It's made by Coin Controls)

Coin Controls also made the technology for smart payphones.
They sometimes get dirty and need to be cleaned. A damp cloth
wiped over the clear plastic tip solves the problem.

Other than the traditional "sample" comparator, optical technology
is quite complex and fairly accurate.

I've never seen those before.  What do you do with it? It doesn't just fit into the standard coin slot does it?

Doesn't it need some kind of control unit to hook up to?

I bet it came off some kind of gambling machine.  Probably set for tokens. (my gut feeling)

I have a Virtua Fighter 3 cab and it uses a Coin Controls validator to connect to a Klingon credit board.

Actualy, I have been thinking of an optical solution for a couple of weeks, because now I have problems with my tripwire. I had to replace the Guilder coinproof with a Euro (0.20 cent) coinproof and it seems the coins are to small/light. Sometimes they pass the wire, and sometimes the coin hangs on the wire without tripping it.
So I was wondering if it could be done opticaly, much more reliable is my guess. Can you put up a picture ? Thx !
