The SNY 2.1mm DC Plug to Terminal Block Adapter provides a professional, solderless connection for your low-voltage power needs. Designed for efficiency and reliability, this adapter bridges the gap between bare-wire power runs and standard barrel-jack ports. Featuring a high-grade 2.1mm x 5.5mm Male Plug and a heavy-duty 2-pin screw terminal, it is the preferred choice for security installers and electronics hobbyists alike.
CCTV & Security Installations: Connect cameras to centralized power supplies using Cat5e, Cat6, or standard 2-core power cable.
LED Strip Lighting: Ideal for connecting custom-cut LED light segments to standard 12V or 24V power adapters.
Prototyping & DIY: A must-have for makers providing power to Arduino, Raspberry Pi (via DC shields), and other board-level projects.
Emergency Repairs: Quickly replace a damaged or frayed DC plug on routers, monitors, or audio equipment without a soldering iron.
Solderless Screw Terminal: The green 2-pin block features high-retention screws that ensure a rock-solid, vibration-proof connection for bare wires.
Standard 2.1mm x 5.5mm Fit: Precision-engineered to fit perfectly into the most common DC sockets found in the surveillance and consumer electronics industries.
Reinforced PVC Body: The rugged, molded black housing includes integrated grip textures for easy plugging/unplugging and serves as built-in strain relief.
Nickel-Plated Contacts: Features high-conductivity nickel-plated brass to ensure stable power delivery and long-term protection against oxidation.
Reliable Polarity Management: The terminal block is clearly marked with "+" (Positive) and "-" (Negative) symbols to prevent wiring errors and equipment damage.
Low-Resistance Transmission: Optimized for high-current applications, ensuring minimal voltage drop and no heat buildup at the connection point.
Industrial Build Quality: Built to endure constant use in both residential DIY projects and professional commercial installations.
Connector A: 2.1mm x 5.5mm DC Male Plug
Connector B: 2-Pin Screw Terminal Block
Compatibility: Fits all standard 2.1mm female DC sockets.
Is this compatible with my 2.5mm device?
No. While very similar in appearance, a 2.1mm plug will not provide a secure connection in a 2.5mm socket. Please verify your device's jack size before purchasing.
Can I use this for PoE systems?
While not for the Ethernet data lines, this is frequently used to provide the DC power input for non-PoE cameras that are being powered via the spare pairs in a Cat5e/Cat6 cable.
Does it require specialized tools?
Not at all! All you need is a standard small flathead or Phillips screwdriver to secure the bare wires into the terminal block.
