4-Pair DC Power Connector Kit
This kit contains four male and four female straight blade plugs sized at 5.5mm outer diameter by 2.1mm inner diameter. The green and black connectors are intended for low-voltage DC power links such as CCTV camera installations. Each pair mates a male barrel to a female barrel for inline or panel connections.
5.5mm x 2.1mm Barrel Dimensions
The critical specification is the 5.5mm outer diameter and 2.1mm inner diameter of the barrel interface. This exact size must match the power input on the camera or accessory you are connecting. A mismatch will prevent a secure fit or cause intermittent power.
Sustained Connection Reliability
The plastic and metal construction weighs 49g total for the set and measures 3.8cm long per connector. Under continuous load the contact surfaces maintain a stable mechanical grip without relying on spring tension that can fatigue. The fixed straight blade geometry resists vibration loosening better than coiled-spring alternatives.

Questions about this item
What does the 5.5 mm outer and 2.1 mm inner diameter mean when I plug it into my camera?
The 5.5 mm outer and 2.1 mm inner diameter match the common barrel jack on many CCTV cameras, so the centre pin and sleeve make full contact without an adapter.
The connector uses a straight blade plug format — what does that limit in practice?
The straight blade plug format means the male and female housings lock together in line, preventing rotation but offering no waterproof seal or locking latch beyond friction.
The total size is 3.8 cm long — will it fit inside a tight camera housing?
At 3.8 cm long, 1.4 cm wide and 1.3 cm high, the pair needs about 4 cm of clear depth; check your housing internal length before ordering.
