In complex PCB layouts where components are crowded or recessed, standard connectors often fall short. The RJ45 8P8C 90-Degree 21mm Long Modular Jack by Pran Electronics Pvt. Ltd. is specifically engineered with an extended body length to bridge the gap between the PCB and the external enclosure.
This unshielded (UTP) version is designed for high-speed Ethernet applications where vertical space is limited, but horizontal reach is required for seamless panel integration.
Optimized Design for Recessed Panel Mounting
The “21mm Long” specification refers to the depth of the connector body. This extra length provides several mechanical advantages:
-
Deep-Enclosure Access: Perfect for devices where the PCB is mounted deep within the chassis, allowing the RJ45 port to sit flush with the outer casing.
-
Reduced Mechanical Stress: The extended 90-degree (Right Angle) profile allows for stable anchoring on the PCB while providing a clear path for Ethernet cable insertion.
-
Thermal Management: The elongated body creates natural spacing between the connector and heat-generating components (like processors or power modules) on the board.
Key Product Features
-
Standard 8P8C Interface: Fully compatible with all Category 5e (Cat5e) and Category 6 (Cat6) RJ45 Ethernet cables.
-
Unshielded (Non-Shielded) Design: A cost-effective, high-performance solution for internal networking environments where EMI/RFI interference is not a primary concern.
-
Precision PCB Mounting: Features robust through-hole (THT) solder pins for superior mechanical strength during repetitive plugging and unplugging.
-
High-Quality Contacts: Selective gold plating over nickel ensures maximum conductivity and prevents oxidation over the product’s lifespan.
-
Durable Housing: Molded from high-temperature, UL 94V-0 rated thermoplastic, ensuring safety and resilience during the wave soldering process.
