## MPN Structure

Harting MPNs follow a structured **11-digit numeric format** with optional separators:

```
[SS] [VV] [PPP] [CCCC]
 |    |    |     |
 |    |    |     +-- Configuration code (4 digits): plating, orientation, etc.
 |    |    +-- Position/Pin code (3 digits): pin count or variant
 |    +-- Sub-series (2 digits): specific variant within series
 +-- Series (2 digits): product family identifier
```

### Format Variations

Harting MPNs can appear in several formats:

| Format | Example | Notes |
|--------|---------|-------|
| Spaced | `09 20 010 2611` | Official Harting format |
| Compact | `09200102611` | No separators |
| Hyphenated | `09-20-010-2611` | Alternative separator |

**All formats are equivalent and handled by the handler.**

## Supported Component Types

The HartingHandler supports:

| ComponentType | Description |
|---------------|-------------|
| `CONNECTOR` | Primary type for all Harting products |
| `IC` | Secondary type (for cross-handler compatibility) |

---

## Configuration Code (Last 4 Digits)

The final 4 digits encode connector configuration details:

| Position | Meaning | Examples |
|----------|---------|----------|
| 1st digit | Plating type | Gold, silver, tin |
| 2nd digit | Contact orientation | Straight, angled |
| 3rd-4th digits | Variant/options | Gender, termination |

**Note**: Harting does not publish a complete public mapping of configuration codes. Use the configuration code primarily for exact part matching, not for extracting specifications.

---

## Helper Methods

The HartingHandler provides several utility methods:

### Series Detection

```java
handler.extractSeries("09 20 010 2611")  // Returns "Han A"
handler.extractSeries("09 33 024 2701")  // Returns "Han E"
handler.extractSeries("21 03 311 1305")  // Returns "M12"
```

### Classification Methods

```java
handler.isHanSeries("09 20 010 2611")       // true
handler.isCircularConnector("21 03 311 1305") // true (M12)
handler.isCircularConnector("21 02 151 0405") // true (M8)
handler.isHighSpeedConnector("02 00 120 1101") // true (har-bus HM)
handler.isPowerConnector("09 30 016 0301")     // true (Han B)
handler.isModularSystem("09 14 008 3001")      // true (Han-Modular)
```

### Specification Extraction

```java
handler.extractPinCount("09 20 010 2611")     // 10
handler.extractPackageCode("09 20 010 2611")  // "2611"
handler.getSeriesCode("09 20 010 2611")       // "0920"
handler.getFamily("09 20 010 2611")           // "Han A/E"
handler.getRatedCurrent("09 30 016 0301")     // 40.0 (Amperes)
handler.getIPRating("21 03 311 1305")         // "IP67"
handler.getApplicationType("09 30 016 0301")  // "High Current Industrial"
```

## Pin Count Extraction

The third group of 3 digits typically encodes the pin count:

| Position Code | Pin Count | Notes |
|---------------|-----------|-------|
| `010` | 10 | Direct mapping |
| `024` | 24 | Direct mapping |
| `016` | 16 | Direct mapping |
| `006` | 6 | Direct mapping |
| `003` | 3 | Direct mapping |
| `311` | 31 | First 2 digits (M12 variant) |

**Algorithm**: For codes < 100, the code equals pin count. For codes >= 100, divide by 10 to get approximate pin count.

## IP Ratings by Series

| Series | IP Rating | Environment |
|--------|-----------|-------------|
| Han A/E/B/D/K | IP65 | Industrial, splash-proof |
| Han-Modular | IP65 | Industrial, splash-proof |
| Han-Yellock | IP67 | Washdown, submersible |
| M12, M8 | IP67 | Washdown, submersible |
| har-bus HM | IP20 | Indoor/enclosure only |
| har-link | IP20 | Indoor/enclosure only |
| har-flex | IP20 | Indoor/enclosure only |

---

## Application Types

| Series | Application |
|--------|-------------|
| Han A, Han E | Industrial Signal |
| Han B | High Current Industrial |
| Han D | Compact Industrial |
| Han K | Power Distribution |
| Han-Modular | Modular Industrial |
| Han-Yellock | Push-Pull Circular |
| har-flex | Flexible PCB |
| M12 | Industrial Sensor/Ethernet |
| M8 | Miniature Sensor |
| har-bus HM | High-Speed Backplane |
| har-link | High-Speed Data Link |

---

## Replacement Logic

Two Harting connectors are considered compatible replacements when:

1. **Same series** (e.g., both Han A, or both M12)
2. **Same pin count** (third group of digits must match or infer same count)

```java
// Compatible - same series, same pins, different config
handler.isOfficialReplacement("09 20 010 2611", "09 20 010 2801")  // true

// Incompatible - different series
handler.isOfficialReplacement("09 20 010 2611", "09 33 010 2701")  // false (Han A vs Han E)

// Incompatible - different pin count
handler.isOfficialReplacement("09 20 010 2611", "09 20 016 2611")  // false (10-pin vs 16-pin)
```

## Learnings & Edge Cases

### MPN Format Handling

- **Format tolerance**: Handler accepts spaces, hyphens, or no separators between digit groups
- **Normalization**: MPNs are uppercased and trimmed before processing
- **Pattern matching**: All 11 series-specific patterns are checked explicitly in `matches()`

### Han A vs Han E Distinction

```
0920 → Han A (first/original Han series)
0933 → Han E (enhanced version)
```

Both return "Han A/E" from `getFamily()` but return distinct series from `extractSeries()`.

### har-flex Special Case

har-flex connectors have a **9-digit format** instead of 11 digits:

```
14 010 1201   (9 digits, no sub-series)
15 020 1301   (9 digits, variant prefix)
```

The pattern `^(14|15)[- ]?([0-9]{3})[- ]?([0-9]{4})$` handles this shorter format.

### Pin Count Edge Cases

For M12/M8 circular connectors, the position code may encode variant information rather than direct pin count:

```
21 03 311 1305 → Position code 311 does NOT mean 311 pins
               → Algorithm: 311 / 10 = 31 pins (approximate)
```

For more accurate pin count on circular connectors, consult the datasheet.

### Configuration Code Not Decoded

Unlike some manufacturers, Harting's configuration code (last 4 digits) is **not publicly documented** in full detail. The handler extracts it for exact matching but does not decode plating, gender, or termination type.

### IC Type Support

The handler supports `ComponentType.IC` in addition to `CONNECTOR`. This is for **cross-handler compatibility** in generic searches, not because Harting makes ICs. All Harting products are connectors.

### Test Location

Tests are in `handlers/HartingHandlerTest.java` (not `manufacturers/` package) to avoid classpath shadowing issues described in CLAUDE.md.
