50-Pack DC Male Plugs 5.5 mm x 2.1 mm
This pack contains fifty straight-blade DC male plugs with a 5.5 mm outside diameter and 2.1 mm inside diameter. Each connector has a 9 mm contact length. They suit repair work, prototyping or bulk cable assembly for standard DC-powered devices.
Solder-Type Inline Connector Limits
These plugs require soldering or crimping to bare wire ends; no screw terminals are present. The 5.5 mm by 2.1 mm barrel size fits only matching female jacks. Polarity follows the centre-positive convention common on many power supplies, so verify the device jack before wiring.
Jack Compatibility Check
Confirm that the target equipment uses a 5.5 mm outer and 2.1 mm inner diameter jack. Measure the existing port if the specification is unclear. Ensure the 9 mm contact depth matches the socket depth to avoid a loose or non-conductive fit.

Questions about this item
Should I choose the 5.5 mm outside diameter version or the 2.1 mm inside diameter version?
This pack contains a single specification: 5.5 mm outside diameter and 2.1 mm inside diameter on every plug.
What does the 9 mm contact length mean once the plug is inserted into my device?
The 9 mm contact length determines how deep the centre pin and barrel engage inside the jack for a solid electrical connection.
Is the 5.5 mm x 2.1 mm size a standard DC barrel interface and what current does it cap in practice?
Yes, 5.5 mm x 2.1 mm is the common barrel standard; the plug itself carries no current rating, so the limit comes from the power supply and cable you attach.
