Coinco Guardian GLX6 6-Tube MDB Coin Changer
The Coinco Guardian GLX (often listed as GLX6 / GLXUS) is a 6-tube MDB coin changer for vending machines. It is the current generation of Coinco’s Guardian line and is commonly used as a replacement for older Guardian 6000 / 6000XL units.
It validates coins electronically, routes accepted coins into six self-replenishing payout tubes or the cash box, and pays change through a single-motor ratchet drive. A lift-out illuminated cassette makes loading faster, and snap-in tubes can be swapped in the field without tools.
