Whether you manage a fleet of 50 ATMs or maintain a single cash dispenser, finding the right spare parts quickly is what keeps downtime short. Hyosung (Nautilus Hyosung) is one of the world's largest ATM manufacturers — their machines run everywhere from bank branches to retail stores and self-service kiosks.
This guide maps out which Hyosung components are cross-model compatible, so procurement teams and service techs know what to stock and what to order.
1. Understanding Hyosung Part Number (PN) Formats
Before we get into specific parts, here's how Hyosung part numbers work:
- Modern format (2016+): Part numbers begin with S prefix — e.g., S21685201, S43025001. The "S" stands for Spare Part, and this is the current standard across all newer manuals.
- Legacy format (pre-2016): Some older manuals, such as the MX-5600 (2010 edition), use pure numeric part numbers without the S prefix — e.g., 5640000008 instead of S5640000008. These are functionally identical to their S-prefixed counterparts.
Important: when searching for parts, always try both formats. A part listed as "21685201" in an older manual is the same component as "S21685201" in current inventory.
2. Hyosung ATM Model Overview
| Model | Type | Cash Handling | Year | Key Features |
|-------|------|---------------|------|-------------|
| NH2700 / NH2100T | Through-the-Wall | Dispense Only | Classic | 4-cassette, EPP encrypted keypad |
| MX-5600 | Lobby / Floor | Dispense Only | 2010 | 4-cassette, 1,000-note stacker |
| MX-5300SE | Lobby | Dispense Only | Mid-gen | Compact footprint, 2-cassette |
| MX-2800SE | Lobby | Dispense Only | Mid-gen | CDU21-based, 2-4 cassette (A-E config) |
| 5100TA | Lobby | Dispense Only | 2023 | Latest model, CDUMR type |
| 5400SE | Floor Stand | Dispense Only | Mid-gen | 4K/6K/8K CST variants |
| MX-8300I | Lobby | Cash Recycling | Advanced | BRM60 + CCIM, deposit+dispense, dual-direction note handling |
| MX-8300D | Floor Stand | Cash Recycling | Advanced | Dual-denom capable, similar sensor array to MX-8300I |
Model note: the "SE" suffix on Hyosung models (MX-5300SE, MX-2800SE, 5400SE) stands for "Special Edition" — typically denoting enhanced software or minor hardware revisions. The spare parts (sensors, motors, belts) are generally interchangeable between SE and non-SE variants of the same chassis generation.
3. Cross-Model Compatible Sensors (Most Requested Parts)
Sensors are the most frequently replaced components in any ATM. The following sensors are verified as compatible across multiple Hyosung models, making them essential stock items for any service operation.
3.1 Infrared Photoelectric Sensors — Note Detection
These sensors detect the presence, position, and authenticity of banknotes as they pass through the cash dispenser module. A failed sensor typically triggers error codes 20001–20005 on the CDU diagnostic screen.
| Part Number | Description | Compatible Models |
|-------------|-------------|-------------------|
| S21685201 / 21685201 | IR Photoelectric Sensor (Emitter) | NH2700, MX-5600, MX-5300SE, MX-2800SE, 5100TA, 5400SE, MX-8300I, MX-8300D |
| S21685202 / 21685202 | IR Photoelectric Sensor (Receiver) | NH2700, MX-5600, MX-5300SE, MX-2800SE, 5100TA, 5400SE, MX-8300I, MX-8300D |
| S21685011 | IR Sensor Assembly | MX-5300SE, MX-2800SE, 5400SE |
| S21683911 | IR Sensor Module | MX-5300SE, MX-2800SE |
The S21685201/202 pair is the single most universal sensor in the entire Hyosung lineup — it appears in all 8 major models. If you stock only one sensor part, this should be it.

When diagnosing note detection errors (20002–20005), always clean the sensor lenses first with IPA (isopropyl alcohol) before replacing. Dust accumulation on IR sensor lenses is responsible for up to 30% of false error reports.
3.2 Pick Module Sensors
| Part Number | Description | Compatible Models |
|-------------|-------------|-------------------|
| S43025001 / 43025001 | Pick-up Roller Sensor | NH2700, MX-5600, MX-5300SE, 5400SE |
| S56403001 / 56403001 | Note Thickness Sensor | NH2700, MX-5600, MX-8300I |
| S56403002 / 56403002 | Note Width Sensor | NH2700, MX-5600 |
3.3 Cassette Position / Presence Sensors
| Part Number | Description | Compatible Models |
|-------------|-------------|-------------------|
| S72840001 | Cassette Presence Sensor | MX-5600, MX-5300SE, MX-8300I |
| S45323001 | Cassette Lock Sensor | NH2700, MX-5600, MX-2800SE |
| S45323002 | Cassette ID Sensor | NH2700, MX-5300SE |
4. Motors & Drive Components
4.1 Main Motors
| Part Number | Description | Compatible Models |
|-------------|-------------|-------------------|
| S5640000008 / 5640000008 | Main Motor (Dispenser Drive) | NH2700, MX-5600, MX-5300SE, 5400SE |
4.2 Pick Module Motors
| Part Number | Description | Compatible Models |
|-------------|-------------|-------------------|
| S7310000262 | Micro-Clutch Assembly | MX-5600, MX-5300SE, MX-2800SE |
| S7310000425 | Drive Roller Motor (Cassette 1) | MX-5600 |
| S7310000426 | Drive Roller Motor (Cassette 2) | MX-5600 |
| S7310000427 | Drive Roller Motor (Cassette 3) | MX-5600 |
| S7310000428 | Drive Roller Motor (Cassette 4) | MX-5600 |
5. Belts & Wear Parts
Belts are consumable items that require regular replacement based on transaction volume. A typical ATM processing 200+ transactions daily should have belts inspected every 6 months.
| Part Number | Description | Compatible Models |
|-------------|-------------|-------------------|
| S43025001 | Pick-up Roller (also listed as sensor in some configs) | NH2700, MX-5600, MX-5300SE, 5400SE |
| Various timing/sync belts | Timing Belt (varies by module) | Model-specific |
Maintenance tip: when replacing belts, always inspect the pick-up roller and timing belt tension simultaneously. A stretched belt accelerates roller wear and causes note pick failures.
6. Cash Dispenser Unit (CDU) Components
6.1 CDU21-Based Models (MX-2800SE, MX-5300SE, 5100TA)
The CDU21 is Hyosung's compact cash dispenser unit, used in lobby machines with 2 to 4 cassette configurations (A through E system).
Key components:
- Cassette frame assembly
- Pick module with independent motor per cassette
- Note transport path sensors (S21685201/202)
- Stacker assembly
6.2 CDUMR Type (5100TA — 2023 Latest)
The 5100TA introduces the CDUMR (Cash Dispenser Unit — Medium-capacity Recirculation-ready) design, representing Hyosung's newest dispenser technology.
Notable: the 5100TA shares the S21685201/202 sensor pair with the MX-5600, ensuring backward compatibility for the most common service part.
7. Cash Recycling Module (MX-8300I / MX-8300D)
The MX-8300 series features the BRM60 (Bulk Recycler Module) and CCIM (Cash Check Insertion Module), enabling both deposit and dispensing from the same cassettes.
Additional sensors and components unique to recycling models:
- Deposit sensor arrays (multi-channel note validation)
- Cassette full/empty level sensors
- Denomination recognition sensors
- Reject bin sensors
These models require more frequent sensor calibration due to the dual-direction note handling.
8. Procurement Tips
Stock priority. For operations managing mixed Hyosung fleets, we recommend maintaining stock in this order:
1. S21685201/202 (IR sensor pair) — Highest universal demand
2. S43025001 (Pick-up roller) — High wear, cross-model compatible
3. S5640000008 (Main motor) — Critical failure, no workaround
4. S7310000262 (Micro-clutch) — Prevents cassette jams
Verify compatibility. Always verify the model name + serial number range before ordering. While cross-model compatibility is well-documented for sensors and motors, some mechanical components (cassette frames, bezels, cable harnesses) may vary between production runs.
OEM vs. aftermarket. OEM Hyosung parts carry the manufacturer warranty but come at a premium. Quality aftermarket alternatives exist for high-demand consumables like pick rollers and belts. For sensors and control boards, we recommend OEM parts for reliability.
