DC Coax/Barrel Jack 2.1 x 5.5 mm Snap-In Panel Mount
This 2.1 x 5.5 mm DC plug has a built-in switch for disconnecting battery packs when an AC/DC adapter is used. Many products require the use of only alkaline batteries for power. This jack, when wired properly, disconnects the batteries when an AC/DC power adapter is plugged in preventing the batteries from accidently being recharged. Non-rechargeable batteries get extremely hot, leak, and damage equipment if charged. The two smaller (-) terminals (tip positive circuit) on the DC jack separate when a 2.1 x 5.5 mm plug is inserted.
The DC jack mounts into holes 12.7 mm in diameter and up to 3.2 mm thick panels. This enables it to quickly mount into metal and plastic panels or project boxes. Total outer diameter for the jack is 14.2 mm and total length without terminals is 14 mm. The tip mounting terminal is 2.72 mm W x 5 mm L x 0.3 mm thick.
