MEI Mars CF7512 5-Tube DCC Coin Mechanism – 25-10-25-25-5 MDB, Refurbished

MEI Mars CF7512 Coin Mechanism – Refurbished 5-Tube MDB Coin Changer

The MEI Mars CF7512 coin mechanism is a five-tube MDB coin changer from MEI’s widely deployed CASHFLOW 7000 series, supplied here fully refurbished and ready to drop into most modern vending machines. It handles the two jobs every cash-taking machine depends on: validating the coins a customer inserts, and paying accurate change back out of its five denomination tubes. This particular unit is the DCC cassette version wired in the 25-10-25-25-5 payout arrangement (three quarter tubes, one dime tube, one nickel tube), a high-capacity layout that keeps a busy machine making correct change through a long service day.

Because it speaks MDB (Multi-Drop Bus) over a standard 6-pin harness, the CF7512 is a direct, plug-compatible changer for the huge installed base of MDB snack, soda, combo, and coffee machines. Paired with an MDB bill validator, it also supplies change for higher-value bills, so operators can run true dollar-and-coin pricing without shortchanging customers. For any operator repairing a dead changer or upgrading an older mech, this is the workhorse part that gets a machine earning again.

Coin acceptance is where vending revenue is either captured or lost. A worn or misconfigured changer rejects good coins, jams, or fails to pay accurate change — and every one of those events is a lost sale and an annoyed customer. The MEI Mars CF7512 coin mechanism was engineered specifically to keep that from happening, with reliable optical and inductive coin discrimination, self-monitoring diagnostics, and a serviceable cassette that technicians can clear and reset quickly. Refurbished and bench-tested before it leaves our facility, this unit gives an operator known-good coin handling at a fraction of the cost of a new mech.

About MEI / Crane Payment Innovations

MEI — originally Mars Electronics International — is one of the most recognized names in unattended payment hardware, and its CASHFLOW 7000 series coin changers have been a vending-industry standard for decades. The brand is now part of Crane Payment Innovations (CPI), which continues to support and manufacture MEI-lineage coin and bill acceptance products. That long production history is exactly why refurbished CF7512 units remain a dependable, cost-effective choice: parts, documentation, and field knowledge are everywhere.

Where This Coin Mechanism Earns

The CF7512 fits any MDB-equipped machine that takes coins: snack and soda vendors in offices, schools, gyms, and break rooms, combo machines in laundromats and apartment blocks, and coin-operated equipment at car washes and amusement locations. Its five-tube capacity makes it especially suited to high-traffic sites where a machine must keep paying change without a mid-day coin refill, and the field-teachable token support opens it up to coin-op laundry and wash bays that run on house tokens.

Adding a working, field-proven changer is typically one of the lowest-cost ways to bring an idle machine back into revenue service — far cheaper than replacing a whole machine, and quick enough that a location can be back online the same day the part arrives.

Because MDB is a shared standard, the same CF7512 can be moved between machines on a route as equipment rotates in and out of service, so it keeps earning even as the fleet changes.
