Connector Adapters & Special Cables
Our connector adapters & special cables are used in applications where you can’t think of why you would ever need them until you need them! They include adapters and cables with a mix of USB and barrel connectors, right-angle bends, thin flat flexible cables (aka FFC cables), cables with connectors at one end and bare wires at the other end, cables with built-in power switches, etc. Check back occasionally to see if we have any new additions, or you can e-mail us at [email protected] with your requirements, and can we see if it’s something we can get or have made up for you from one of our custom cable manufacturers.

6.5-ft Power Cable - OUTDOOR RATED (IP66) - REGULAR-DUTY - 22AWG - 2A - 5.5mm x 2.1mm Male Barrel Plug with M12-1.75 Screw Threads - Pair of Tinned  Bare Conductors - Works with Outdoor Battery Eliminator Kits 6.5-ft Power Cable - OUTDOOR RATED (IP66) - REGULAR-DUTY - 22AWG - 2A - 5.5mm x 2.1mm Male Barrel Plug with M12-1.75 Screw Threads - Pair of Tinned Bare Conductors - Works with Outdoor Battery Eliminator Kits

This OUTDOOR RATED (IP66), REGULAR-DUTY, 22AWG, 6.5-ft (2m) long DC power cable can handle up to 2A of current. This outdoor cable has an M12-1.75, 5.5mm x 2.1mm male barrel plug at one end of the cable, and the other end of the cable has a pair of 2mm bare conductors (see illustrations) that are tinned and ready to be soldered to the appropriate points in an electronic circuit. This outdoor power cable is intended for the do-it-yourselfer with the equipment and skills necessary to solder the stripped and tinned bare ends of the cable to the appropriate points in an electronic circuit. The most common application of this outdoor cable is to replace an existing power cable on a solar panel since most solar panels on the market do not have outdoor rated (IP66) power cables. Most solar panels on the market have simple “push-to-connect” type 5.5mm x 2.1mm male barrel plugs which allow water and dirt to penetrate which eventually leads to an unreliable connection due to corrosion and degradation of the electrical connection between barrel connectors. The M12-1.75, 5.5mm x 2.1mm male barrel plug at one end of this outdoor rated cable creates a weatherproof seal when the M12-1.75 screw connector is mated with an appropriate M12-1.75, 5.5mm x 2.1mm female barrel socket. A weatherproof seal is created by compression of the rubber O-ring on the M12-1.75, 5.5mm x 2.1mm male barrel plug when mated with the appropriate M12-1.75, 5.5mm x 2.1mm female barrel socket (refer to illustrations) such as those found on our outdoor rated battery eliminator kits and outdoor accessories such as our outdoor power extension cables, outdoor power splitter cables, and outdoor active dummy cell batteries. This outdoor power cable can also serve as a replacement of the power cables found on our outdoor solar panels and modules.
