DC 5.5x2.1 mm Magnetic Charging Cable

Overview

Magnetic charging cable with a 5.5 x 2.1 mm coaxial DC jack on the device side. The DC jack is the most common low-voltage DC barrel size on CCTV cameras, LED strip drivers, routers, small household appliances and hobby electronics. The magnetic coupling lets the user pull the cable free without stressing the device socket.

Construction and Materials

Two-conductor 20 AWG tinned copper, PVC jacket. The DC jack end is a custom moulded magnetic head with two pogo pins contacting the inner pin and outer sleeve of the DC jack. Centre-positive polarity is the default; the magnet and pin geometry can be flipped to centre-negative without changing the mould.

Typical Applications

CCTV cameras, DVR and NVR power adapters where breakaway cables prevent the camera from being pulled off the wall
LED strip drivers and small DC fans
Routers, set-top boxes and small network gear
Hobby electronics and bench supplies
