Frequently Asked Questions
What are the PCB layout and mounting hole dimensions for this RJ45 8P8C modular jack?
For precise through-hole PCB integration, the layout requires 8 signal pin holes of Ø0.90mm on a 1.02mm staggered pitch, 4 LED pin holes of Ø1.02mm, 2 shield grounding slots/holes of Ø1.60mm spaced 16.26mm apart, and 2 locating peg holes of Ø3.20mm spaced 12.70mm apart.
Why does this RJ45 connector use 50 micro-inch gold plating on the terminals?
The 50μ" thick gold plating over 0.35mm phosphor bronze terminals provides superior oxidation resistance and electrical conductivity, maintaining contact resistance below 30 mΩ initially and under 50 mΩ after 750 mating cycles in industrial environments.
What are the electrical specifications for the integrated Yellow and Green LEDs?
Both the left Yellow LED (585nm wavelength) and right Green LED (568nm wavelength) operate at a standard forward current of 20mA, with a forward voltage range of 1.7V to 2.2V for Yellow and 1.85V to 2.45V for Green.
Can this shielded RJ45 jack operate in extreme industrial temperatures?
Yes, constructed with UL94V-0 black PBT housing and a C2680 nickel-plated brass shield, this connector is rated for continuous operation and storage across an industrial temperature range of -40°C to +85°C while withstanding 1000 VAC dielectric testing.
Overview and Application Notes
This RJ45 8P8C Shielded Modular Jack is a high-reliability, right-angle PCB through-hole network connector engineered for industrial Ethernet, telecommunications, and embedded networking hardware. Outfitted with a nickel-plated brass EMI/RFI shield with panel-grounding flanges and integrated dual LED status indicators (Yellow/Green), it delivers superior signal integrity and real-time link activity monitoring. Its 50μ” gold-plated phosphor bronze contacts ensure stable conductivity and corrosion resistance across demanding operating environments from -40°C to +85°C.
Key Features
- 50μ” Gold-Plated Contacts: Precision 0.35mm phosphor bronze terminals with 50 micro-inches of gold plating on the contact area guarantee low contact resistance (≤30mΩ) and a minimum durability of 750 mating cycles.
- Enhanced EMI/RFI Shielding: Enclosed in a 0.20mm C2680 brass outer shell with 20μ” min. nickel plating and grounding flanges to suppress electromagnetic interference.
- Integrated Dual LEDs: Built-in Left Yellow (585nm) and Right Green (568nm) LEDs provide clear visual diagnostics for network link status and data transmission rates.
- Industrial Temperature Grade: Black UL94V-0 PBT thermoplastic housing withstands extreme operating and storage temperatures from -40°C to +85°C.
- High Mechanical Retention: Provides a secure 7.7 kgf minimum retention strength between jack and plug with a smooth 2.2 kgf maximum insertion force.
Engineering Specifications & PCB Integration
Designed for right-angle through-hole technology (THT) mounting, this 8P8C connector features a 16.50mm front width, 13.50mm profile height, and 15.75mm body depth. The recommended PCB layout requires 8 signal pin holes (Ø0.90mm at 1.02mm pitch), 4 LED pin holes (Ø1.02mm), 2 metal shield grounding tabs (Ø1.60mm spaced at 16.26mm), and 2 plastic mounting pegs (Ø3.20mm spaced at 12.70mm) for precise board alignment and strain relief during wave soldering.
