Быстрый ответ: Cable matching is critical for reliable connections. Key factors: Cable outer diameter (must fit connector), number of conductors (must match connector pins), conductor size (must handle your current), jacket material (must suit your environment). We offer cable assembly service – send us your cable specs or samples and we’ll match the right connector. Popular cable types: Polyurethane (flexible, ROV), TPE (general purpose), Polyethylene (deep water). Tell us your cable OD and we’ll recommend compatible connectors.
Cable-Connector Matching Guide
Key Matching Factors
1. Cable Outer Diameter (OD)
Most critical dimension! Connector must grip cable properly.
| Cable OD Range | Compatible Connector Series | Gland Size |
|---|---|---|
| 4-6mm | MCM miniature series | Small |
| 6-10mm | MCBH 2-6 pin | Средний |
| 10-14mm | MCBH 8-12 pin | Large |
| 14-20mm | MCBH 14-24 pin | Extra Large |
| 20mm+ | Custom connectors | Custom |
2. Number of Conductors
Must match connector pin count (or use fewer pins than available).
- 2 conductors → 2-pin connector (or larger)
- 4 conductors → 4-pin connector (or larger)
- Cannot use 6-conductor cable with 4-pin connector (waste)
- Can use 4-conductor cable with 6-pin connector (2 pins unused)
3. Conductor Size (Wire Gauge)
Must handle your current without overheating.
| Wire Gauge (AWG) | Max Current | Лучшее для |
|---|---|---|
| 22 AWG | 3A | Signal, low power |
| 20 AWG | 5A | Signal, sensors |
| 18 AWG | 10A | Control, medium power |
| 16 AWG | 15A | Power, thrusters (small) |
| 14 AWG | 20A | Power, thrusters (medium) |
| 12 AWG | 30A | High power |
| 10 AWG | 40A | Very high power |
4. Jacket Material
Must suit your environment.
| Jacket Material | Лучшее для | Температура | Flexibility |
|---|---|---|---|
| Полиуретан (PUR) | ROV, high flex | -40°C до +80°C | Превосходно |
| TPE | Морской генерал | -30°C to +70°C | Очень хорошо |
| Polyethylene (PE) | Deep water, static | -50°C to +60°C | Хорошо |
| PVC | Freshwater, budget | -15°C to +60°C | Ярмарка |
| Neoprene | Oil & gas | -40°C to +90°C | Хорошо |

Cable Preparation Tips
For Connector Installation
- Strip outer jacket: Carefully, don’t nick conductors
- Prepare conductors: Strip to correct length
- Tin conductors: Solder tip for easier insertion
- Insert into connector: Follow pinout diagram
- Pot/seal: Use epoxy or potting compound
- Assemble connector: Follow torque specifications
Распространенные ошибки, которых следует избегать
- ❌ Cable OD too small (won’t seal properly)
- ❌ Cable OD too large (won’t fit in connector)
- ❌ Conductors too large for contacts
- ❌ Wrong stripping length
- ❌ Damaged conductor insulation
- ❌ Inadequate potting/sealing
