M12 L-code connectors are widely used in industrial automation power supply systems with their current carrying capacity up to 16A and compact structure. In response to different equipment requirements, M12 power L-code connectors provide a variety of pin combinations, such as 2 Pin, 3+PE, 4+PE, 4+FE, etc. Each type has its specific application scenario.
List of Common PIN Position Types
| Pin Configuration | Description | Typical Applications |
|---|---|---|
| 2 Pin | Simple positive and negative supply | Small modules, sensors |
| 2+PE | Positive, negative + protective earth (PE) | Low-power devices with safety requirements |
| 3+PE | Three-phase supply + PE | Single-phase power systems |
| 4+PE | Four-phase supply + PE | Power distribution boxes, modular systems |
| 4 Pin | Four-phase supply without ground | Devices with non-metal housings |
| 4+FE | Four-phase supply + functional earth (FE) | Systems with high EMC requirements |

Selection suggestions
- Power supply for small equipment: choose 2 Pin or 2+PE version, compact structure and flexible installation.
- General single-phase power supply system: 3+PE or 4+PE is recommended to meet daily industrial control needs.
- For complex or interference-sensitive equipment: it is recommended to choose a version with FE function (such as 4+FE) to improve anti-interference ability.
The correct selection of pin position combination is the key to ensuring the safety and compatibility of the power supply system.
