Long-Barrel Female DC Power Pigtail Connector (5.5×2.1mm, Red & Black Leads)

Product Overview

The DC-CORFEM Female DC Power Pigtail Cable is an essential power termination accessory engineered for CCTV video surveillance cameras, LED lighting arrays, access control hardware, and low-voltage electronic assemblies. Featuring an industry-standard 5.5 mm outer diameter by 2.1 mm inner pin center (5.5×2.1mm) female barrel receptacle, this extended long-version connector allows technicians to transition standard 12V/24V DC power adapters into clean, stripped wire terminations without cutting factory power supplies.

Constructed with high-conductivity copper conductor wire and insulated in durable, color-coded red (positive) and black (negative/ground) PVC jackets, the DC-CORFEM simplifies circuit polarity identification in the field. The extended barrel length ensures deep, positive retention inside male plug receptacles, preventing accidental disconnections caused by cable movement or vibration. With factory pre-stripped and tinned wire ends, it connects into terminal blocks, lever nuts, or screw barrier strips found on centralized power distribution boxes, video baluns, and access control power management units.

✅ Key Features

• Standard 5.5×2.1mm Female Barrel Interface: Universal inner/outer diameter matches standard low-voltage security cameras and DC power supplies.

• Long-Barrel Extended Profile: Reinforced plug body provides deeper connector seating, strain relief, and vibration-resistant mechanical retention.

• Color-Coded Polarity Leads: Distinct red (+ Positive / Center) and black (- Negative / Shell) wire leads eliminate cross-polarity wiring errors.

• Pre-Stripped & Tinned Wire Ends: Stranded copper wire tips are factory-stripped and solder-tinned for immediate screw-terminal or solder termination.

• High-Flexibility PVC Outer Insulation: Flame-retardant jacket protects internal copper conductors from abrasion, moisture, and bending fatigue.

• High Electrical Conductivity: Pure copper stranded core minimizes DC voltage drops across low-voltage camera runs.

• Plug-and-Play Field Termination: Eliminates splicing or destroying OEM power adapter cables during installation or maintenance.
