Conlux MCM5 5-Tube MDB Coin Mechanism – $1 Cassette, 6-Pin, Refurbished

Conlux MCM5 Coin Mechanism – Refurbished 5-Tube MDB Changer

The Conlux MCM5 coin mechanism is a refurbished, high-capacity 5-tube MDB coin changer configured with the $1 cassette and a 6-pin harness. It accepts and validates US coinage and pays back change from five tubes in a 5¢ / 10¢ / 25¢ / 25¢ / $1 configuration, making it a direct-fit replacement for the coin mech in virtually any Multi-Drop Bus (MDB) vending machine — snack, soda, combo, or specialty.

Built around a removable high-capacity cassette, the MCM5 holds up to two full rolls of coins per tube and eliminates the change starvation that stalls sales on busy routes. It delivers up to three coins simultaneously for faster payout, and its tubes are accessible from the back of the cassette so operators can top off change quickly during a service stop. This is the part that keeps a machine taking money instead of flashing “Use Correct Change.”

Specifications

Key features

• High-capacity cassette — each tube accommodates two full rolls of coins, cutting change-starvation downtime on high-traffic locations.
• Fast payout — simultaneous three-coin dispensing speeds transactions and keeps lines moving during peak periods.
• Rear-loading tubes — coins fill from the back of the cassette, so route drivers refill change without pulling the whole mech.
• Low idle draw — engineered to use roughly 30% less power at idle than comparable changers.
• Simple programming — a 9-button keypad and clear labeling make coin inhibit, tube fill, and diagnostic routines quick to run.
• Universal MDB fit — mounts on the standard three studs and plugs into the MDB coin harness used across the industry.

About Conlux and CPI

Conlux is a long-established coin-handling brand now part of Crane Payment Innovations (CPI), one of the largest makers of unattended-payment hardware for vending, amusement, and self-service equipment. The MCM5 changer sits alongside CPI bill validators and cashless readers as a proven, field-serviceable coin platform, which is why it remains a go-to mech for operators standardizing a fleet on MDB payment hardware.

Where this coin mechanism earns

Because it is a universal MDB part, the MCM5 fits the machines that anchor most routes — snack and combo vendors in offices and break rooms, soda machines in gyms and laundromats, and specialty units at car washes and hotels. Any location that still takes cash benefits from the larger cassette: fewer “exact change” lockouts means fewer walked-away sales. Operators typically keep a spare coin mech on the truck so a failed changer is a five-minute swap instead of a dead machine, and the MCM5’s rear-fill tubes make routine change top-offs faster on every visit.

Frequently asked questions

What coins does the MCM5 pay out? This unit is configured 5¢ / 10¢ / 25¢ / 25¢ / $1 across its five tubes, so it can accept and return nickels, dimes, quarters, and $1 coins.

Will it fit my vending machine? The MCM5 is a standard MDB coin changer that mounts on the usual three studs and uses the 6-pin MDB coin harness. It fits virtually any MDB-equipped snack, soda, or combo machine. If your machine is older single-price or pulse-based, confirm it supports MDB before ordering.

What power does it need? It runs on the 34 VDC supplied over the MDB bus, drawing about 12 W (0.92 A) — there is no separate power supply to add; the machine’s MDB harness powers it.

Is this new or refurbished? It is a refurbished unit — tested, cleaned, and verified working before shipment — not new.

What warranty comes with it? A 1-year limited warranty on the refurbished part, plus remote tech support for US customers.

Can I add a card reader to the same machine? Yes. Because the machine uses the MDB bus, you can run this coin mech alongside an MDB bill validator and a cashless/credit-card reader (such as a Nayax unit) on the same harness for full cash-plus-card acceptance.

How is it delivered? As a boxed part via ground shipping, free within the continental US, typically dispatched within 1–2 business days of payment.

How do I program the coin values and tube fill? The MCM5 uses a 9-button keypad with labeled functions for coin inhibit, manual tube fill, and diagnostics, so setup is done on the mech itself — no external programmer required. Once mounted and plugged into the MDB harness, the machine controller reads the changer automatically, and you can top off each tube through the rear-loading cassette.

Why choose a 5-tube changer over a 3-tube unit? The extra tubes and high-capacity cassette hold far more change — up to two full rolls per tube — which is what prevents the “exact change only” lockouts that cost sales on high-traffic locations. For busy offices, gyms, or 24-hour sites, the added change reserve pays for itself in captured transactions.
