Refurbished AMS 39-640 Snack Vending Machine

Refurbished AMS 39-640 Snack Vending Machine

The AMS 39-640 snack machine is the value-tier member of the AMS 39 family: a 39-inch-wide merchandiser built on the earlier Sensit control generation. This refurbished unit gives operators the same proven AMS hardware and footprint as the current Sensit 3 model at a lower entry price, which makes it a smart first machine for a new route or an inexpensive second unit for a growing one.

Because the AMS platform barely changed its mechanical core across Sensit generations, a refurbished 39-640 is just as serviceable as a newer machine. Parts interchange, the door and tray geometry match the rest of the line, and most field technicians already know it inside out. On a refurbished purchase, the control-board revision and the bill-and-coin acceptance matter far more than the badge on the front panel.

What the AMS 39-640 Snack Machine Offers

This snack build carries a full multi-shelf product menu and uses the AMS Sensit guaranteed-delivery sensor, an infrared beam that confirms the product actually dropped and automatically refunds the customer when one hangs. The high-capacity tray layout suits busy break areas that would empty a smaller machine. Payments run over the MDB bus, so a modern card or tap reader plugs straight in alongside coin and bill acceptance. Full platform documentation is published by AMS.

Best-fit locations

This snack-only build suits offices, gyms, dorms, and breakrooms in the 30-to-150-person range. It is a strong budget entry where you want dependable AMS mechanics without paying for the newest controller. If the spot also needs cold drinks, pair it with a beverage machine or step up to a combo cabinet.

Can it take cards?
Yes. The MDB bus accepts a card or tap reader alongside coin and bill payment.

Does it vend drinks?
No, this is a snack-only build; choose an AMS 39 combo for snacks and cold drinks together.
