Ex approval
PCB terminal blocks and PCB connectors with Ex approval
The PCB terminal blocks and PCB connectors range from Phoenix Contact, with Ex approval, is specially designed for use in potentially explosive areas. The products have component approval according to the IEC/EN 60079-0 and IEC/EN 60079-7 standards, which define the requirements for devices in potentially explosive atmospheres.
The use of PCB connections in process technology places higher demands on the following properties:
- Air clearances and creepage distances
- Heating response
- Resistance to aging
- Insulation capability of insulation materials
Always the right solutions for Ex applications
The comprehensive product range from Phoenix Contact offers you the necessary flexibility when selecting conductor connection technology:
- PCB terminal blocks and PCB connectors
- Pitch 5.0, 5.08, and 7.62 mm
- Screw connection, push-in or spring connection
- PCB terminal blocks and headers of the connectors suitable for the wave soldering process
When using PCB terminal blocks and PCB connectors with Ex approval, please observe the installation instructions. This information can be downloaded under the relevant product documentation.
Approval:
| Combustible material | Gas, vapor, liquid, dust |
|---|---|
| Type of protection | Ex e (increased safety) |
| Equipment group | II |
| Equipment category | 2 GD |
| Equipment protection level | Gb (occasional occurrence of combustible materials) |
| Gas group | IIC (ignition energy < 60 μJ) |

Ex i marking according to IEC/EN 60079-11
For intrinsic safety Ex i protection according to IEC/EN 60079-11, both PCB terminal blocks and PCB connectors with Ex approval and standard products can be used. The setup of intrinsically safe circuits also requires adherence to the specified air clearances and creepage distances. The connection points of these circuits must be clearly marked. Color coding is light blue.
