Streamline your low-voltage power installations with the 2.1mm DC Plug to Terminal Block Adapter. This essential connector eliminates the need for specialized crimping tools or messy soldering, allowing you to bridge the gap between bare-wire power runs and standard barrel-jack equipment. Featuring a precision-machined 2.1mm x 5.5mm Male Plug and a secure 2-pin screw terminal, it is the perfect solution for CCTV cameras, LED lighting, and custom electronics projects.
CCTV & Security Systems: Connect security cameras to centralized power supplies using UTP or standard 2-core power cable.
LED Strip Installations: Easily bridge the gap between a standard 12V/24V power adapter and custom-cut LED strip light segments.
DIY Electronics & Robotics: A must-have for makers needing to provide power to Arduino boards, sensors, or motors from a bare-wire source.
Field Repairs: Quickly replace a damaged power plug on routers, hubs, or monitors using only a small screwdriver.
Solderless Screw Terminal: The green 2-pin (+/-) block features high-retention screws that provide a solid, vibration-resistant connection for bare copper wires.
Universal 2.1mm x 5.5mm Fit: Designed to work with the most common DC barrel size used in consumer electronics and surveillance hardware.
Industrial-Grade Strain Relief: The rugged black PVC housing is molded with grip textures to protect internal connections from physical stress and pulling.
High-Conductivity Contacts: Features nickel-plated brass contacts to ensure maximum power delivery and resistance to oxidation.
"Tool-Free" Efficiency: Install or swap power connections in seconds using only a small flathead screwdriver, saving significant time on-site.
Stable Power Delivery: Engineered for low-resistance transmission, ensuring your devices receive steady voltage without heat buildup at the connection point.
Marked Polarity: Clearly labeled with "+" and "-" symbols on the terminal block to prevent accidental reverse-polarity damage to your equipment.
Connector A: 2.1mm x 5.5mm DC Male Plug
Connector B: 2-Pin Screw Terminal Block (Positive/Negative)
Will this fit a 2.5mm port?
No. While they look similar, a 2.1mm plug will feel "loose" or fail to make contact in a 2.5mm socket. Please verify your device's barrel size before ordering.
Can I use this with Cat5e/Cat6 cable?
Yes. You can use the twisted pairs inside an Ethernet cable to carry DC power to your devices, which is common in CCTV setups.
Is it safe for 24V systems?
Yes. This adapter is rated for standard low-voltage DC applications (up to 36V), making it ideal for 12V and 24V LED drivers and security hardware.
