JacobsParts Inc. DCCONN-C Straight Blade Plug 5.5mm x 2.1mm 30cm 2-Pack

Ready-to-use DC power pigtails

These two pre-stripped cables add a 5.5 x 2.1 mm female barrel jack to any low-voltage project. Each lead measures 30 cm of wire with a 40 cm overall length and ends in tinned red and black conductors for immediate soldering or terminal connection. Center-positive polarity is fixed with red for positive and black for negative. The pack suits hobbyists, installers and repair technicians who need a quick, solder-free power interface.

Molded strain relief and PVC jacket

Black PVC insulation covers the full cable run and the molded jack body, protecting the conductors from flex damage during routing. The straight-blade barrel fits panel-mount and inline sockets without adapters, so the plug seats securely in tight enclosures or behind mounted equipment. Pre-stripped ends eliminate the need for wire strippers on site, reducing installation time for CCTV cameras, LED strips or DVR units. No mounting hardware is included, so the builder supplies any panel nuts or cable ties required.

Low-loss conductors for cool operation

The short 30 cm conductor run keeps resistive loss and self-heating negligible at typical 12 V DC loads. No active cooling is required and the assembly runs silently in enclosed cabinets or conduit. The tinned ends resist oxidation, maintaining low contact resistance over repeated connect-disconnect cycles. The lightweight 0.176 oz pair adds no measurable strain to solder joints or terminal blocks. Builders needing longer runs or higher current capacity should select a heavier-gauge harness.
