Product details

Shielded RJ45 Jack with Integrated Status LEDs

It carries a Cat3 rating, which limits its signal bandwidth to 16 MHz — suitable for 10BASE-T and 100BASE-TX Ethernet, but not for Gigabit or higher-speed protocols that require Cat5e or better. The jack includes green and yellow LED indicators for link and activity status, a common feature for panel-mount Ethernet jacks that saves the cost of separate indicator components. The shielded housing helps contain EMI emissions and protect the signal path in electrically noisy environments like factory floors or telecom racks.

Contact Plating and Mating Reliability

Contacts are phosphor bronze with 50.0 µ" (1.27 µm) gold plating over the mating surface. The housing is glass-filled PA46 (Nylon 4/6), which handles the reflow temperatures of lead-free soldering without distortion.

Frequently asked questions

Is 1734577-3 compatible with Cat5e cables?

No. The 1734577-3 is rated Cat3, which limits its signal bandwidth to 16 MHz. Cat5e cables require a connector rated to 100 MHz. While the physical 8p8c interface will accept a Cat5e plug, the jack will not pass the Cat5e signal integrity requirements for Gigabit Ethernet.

What is the pinout of 1734577-3?

The 1734577-3 uses the standard 8p8c (RJ45) pinout, with positions 1 through 8 corresponding to the T568A or T568B wiring schemes. The integrated green and yellow LEDs are independently wired and do not affect the signal path.
