The Vending Machine MDB Extension Cable is a 5-foot cable designed specifically for vending machines. It is used to extend the length of the cable that connects the vending machine to the MDB (Master Bill Validator) system. This extension cable ensures that the vending machine can still be operated and dispense products even if the power source is located further away. It is a crucial accessory for maintaining the functionality of vending machines in various settings, such as restaurants, convenience stores, and other establishments where vending machines are commonly used.
