Frequently Asked Questions (FAQ)
- Q: What does the "PA-H" suffix in the part number signify?
A: The "PA-H" suffix typically indicates a specific variant within the J599 KF series, often denoting particular features such as a specific contact layout (e.g., mixed power/signal), a specialized plating, or a version qualified for higher performance parameters. Please consult our technical datasheet for the specific attributes of the PA-H variant. - Q: What is the maximum current rating for the power contacts in this connector?
A: While the standard test rating is 1A @ 28V DC, the actual maximum current capacity depends on the specific contact size and wire gauge used. We offer contacts with higher current ratings (e.g., 5A, 10A, 20A) within the same shell. Please specify your current requirements for a tailored solution. - Q: Is this connector compatible with existing J599 KF series sockets in the field?
A: Yes, the J599 26KF32PA-H is designed to be intermutable with other J599 Series III, shell size 26, KF-style connectors, ensuring backward compatibility and ease of integration into existing systems. - Q: Can you provide connectors with built-in transient voltage suppression or filtering?
A: Absolutely. We can integrate filtered contacts containing capacitors, inductors, or transient voltage suppressors (TVS) directly into the connector insert to provide EMI/RFI filtering and circuit protection at the interface point. - Q: What is the typical lead time for a customized order of this connector?
A: Lead time depends on the complexity of customization and order quantity. For standard configurations, we maintain efficient stock or production cycles. For customized orders, we provide a detailed project timeline upon receipt of your specific requirements. We prioritize communication to ensure timely delivery for your program needs.
