Import 5.5*2.1mm Female Dc Plug For Cctv — Buy in wholesale FOB from Supplier in China

Chinasky Electronics Co. Limited manufactures a 5.5x2.1mm female DC barrel plug designed for 12V DC power distribution in closed-circuit television and security camera installations. The connector mates with standard male DC plugs carrying the same 5.5 mm outer diameter and 2.1 mm inner pin dimension, a de facto industry standard for low-voltage CCTV power. The supplier specifies copper alloy contacts with nickel or gold plating options, housed in either PVC or ABS insulating bodies, with screw terminal termination for field wiring without soldering equipment. This configuration targets installers and maintenance technicians requiring rapid, tool-free connection changes in distributed surveillance networks.

The contact material selection carries implications for corrosion resistance and contact resistance stability in environments ranging from climate-controlled server rooms to outdoor installations with humidity cycling. Copper alloy with nickel plating offers cost-effective oxidation protection adequate for indoor and protected outdoor use; gold plating, at additional cost, provides superior low-resistance stability for critical applications or where connector mating cycles exceed typical maintenance frequencies. Housing material choice between PVC and ABS affects flame retardancy, UV resistance, and mechanical robustness, with ABS generally offering higher impact resistance and PVC providing greater flexibility in cable strain relief designs. The screw terminal design accepts stranded copper conductors typically ranging 22-18 AWG, though buyers should confirm maximum conductor diameter and recommended torque to prevent thread stripping or loose connections.

Primary applications include power input connections for bullet cameras, dome cameras, DVR/NVR power port extensions, and LED illumination arrays in retail loss prevention, banking security, transportation monitoring, and residential surveillance systems. The product serves security integrators, CCTV distributors, and maintenance contractors sourcing bulk connectors for installation fleets or spare parts inventory. Chinasky Electronics is located in Hangzhou, Zhejiang Province, with the source indicating standard export packaging and FOB/CIF shipping options. Exact MOQ, pricing, lead times, and certification scope are not provided in the listing and require direct supplier confirmation. Buyers should specify whether their deployment environment requires UL-listed, CE-marked, or RoHS-compliant components before finalising specifications.

Chinasky Electronics Co. Limited operates from Xiacheng District, Hangzhou, Zhejiang Province, China, a city with established electronics manufacturing and e-commerce infrastructure. The supplier holds a harbor trust tier with a recorded response rate of 0.00% and zero average response hours, metrics that may indicate incomplete platform tracking rather than non-operational status. The source provides no information on factory ownership model, year of establishment, employee count, annual revenue, or facility certifications such as ISO 9001. Buyers should treat any assumed scale or longevity as unverified until documentation is requested.

The company's product focus centres on CCTV accessories and surveillance system components, with this female DC plug representing a standardised connector within broader security equipment portfolios. The listing targets B2B buyers including security system integrators, CCTV installers, and equipment distributors serving retail, financial, and transportation verticals. No information on export licence scope, existing market presence, or reference customer installations is provided. Buyers should verify whether Chinasky maintains in-house injection moulding and contact plating capabilities or operates as a trading company aggregating third-party manufacturing, as this distinction affects quality control consistency and supply chain transparency.
