Application Fit and Selection Considerations

When selecting an FD series connector, consider the following factors to ensure proper mating and performance:

• Electrical load – Confirm the current and voltage requirements of your application
• Pin configuration – Verify the required pin count and layout against your wiring diagram
• Mounting style – Choose between flange, panel, docking, or cable mount based on your equipment design
• Environmental exposure – Assess the IP rating needed for your operating environment
• Cable specifications – Provide the cable outside diameter and conductor size for proper termination

Unsuitable Applications

FD series connectors are not recommended for applications requiring submersion beyond the rated IP protection, extreme temperature ranges outside the specified limits, or mating cycles exceeding the rated durability. For such requirements, consult our engineering team for alternative solutions.
