🔌 What Is a PoE RJ45 Connector?
A PoE RJ45 connector is a network interface module that supports Power over Ethernet—delivering both data and DC power through the same cable. Unlike a standard connector, a PoE-capable RJ45 includes enhanced isolation, optimized magnetic design, and sometimes higher voltage tolerance.
🧲 Are LINK-PP RJ45 Connectors Magnetically Integrated?
Yes. All LINK-PP PoE RJ45 connectors are magnetically integrated, combining Ethernet transformers (magnetics), common-mode chokes, and RJ45 jacks into a single, compact unit. This improves EMI performance, saves PCB space, and simplifies the manufacturing process.
⚙️ What Are the PoE Standards Supported?
LINK-PP connectors are designed to support the following IEEE standards:
PoE (IEEE 802.3af): Provides up to 15.4 watts, suitable for devices like VoIP phones and basic IP cameras.
PoE+ (IEEE 802.3at): Delivers up to 30 watts, ideal for more power-intensive devices such as advanced cameras and wireless access points.
PoE++ (IEEE 802.3bt): Offers up to 60 watts or more, supporting high-performance devices like pan-tilt-zoom cameras and industrial equipment.
These standards ensure reliable performance for devices like IP cameras, VoIP phones, access points, and more.
🌡️ What Is the Operating Temperature Range?
Our industrial-grade models support wide temperature ranges:
Standard: 0°C to +70°C
Industrial: -40°C to +85°C
This makes them suitable for both commercial and rugged environments.
📐 What Mounting Options Are Available?
We offer a wide range of mounting styles, including:
Through-Hole (THT)
Surface Mount (SMT)
Vertical and Right Angle configurations
This flexibility allows seamless integration into various PCB layouts.
🔒 Are LINK-PP PoE RJ45 Connectors Safe and Certified?
Absolutely. Our connectors comply with key global certifications and standards:
IEEE 802.3 Ethernet protocols
UL, RoHS, REACH compliant
High-pot (Hi-Pot) test voltage up to 1500Vrms or 2250VDC, ensuring strong isolation between power and data paths.
🧩 Can LINK-PP Products Replace Other Major Brands?
Yes. LINK-PP RJ45 connectors are fully compatible with popular brands like:
Pulse Electronics
Halo Electronics
Belfuse
Tyco / TE Connectivity
We offer cost-effective alternatives with equivalent or better performance.
❓ How Do I Know If My Device Is Compatible with LINK-PP PoE RJ45 Connectors?
Check your device’s specifications. Ensure it supports one of the PoE standards (PoE, PoE+, or PoE++). Also, verify that your Ethernet cable meets the required category, such as Cat5e or higher.
🛠️ Does the LINK-PP PoE RJ45 Connector Require Special Tools for Installation?
You’ll need only basic tools such as a crimping tool and a cable tester. These tools help you secure the connector to the Ethernet cable and verify the connection’s functionality.
🔧 How Can I Maintain the LINK-PP PoE RJ45 Connector for Long-Term Use?
To ensure long-term performance:
Clean the connector regularly to remove dust.
Avoid bending or over-flexing the cables.
Inspect periodically for damage or wear, and replace if needed.
Proper handling and maintenance can significantly extend the connector’s service life.
