FAQs

Q: Does this support Power over Ethernet (PoE)?
A: Yes, the integrated magnetics are compatible with PoE applications per IEEE 802.3af standards.

Q: What is the purpose of the EMI finger?
A: The brass EMI finger creates a grounding path between the connector shield and chassis, reducing electromagnetic interference.

Q: Can this connector handle industrial temperature ranges?
A: This variant operates at 0°C to 70°C. For extended temperatures (-40°C to 85°C), inquire about industrial-grade alternatives.

Q: Why choose jacks with integrated magnetics?
A: Integrated magnetics reduce board space, simplify design, improve signal quality, and lower total system cost versus discrete solutions.

Q: Is the gold plating sufficient for frequent mating cycles?
A: The 15µin gold plating on phosphor bronze contacts ensures durability for 1,500+ mating cycles in standard applications.

Q: How does AutoMDIX functionality benefit my design?
A: AutoMDIX automatically detects and corrects transmit/receive pairs, eliminating crossover cables and simplifying installation.
