DC coaxial power connector, male barrel jack - cable mount

Product detailed description

DC coaxial power connector (so-called barrel jack) in a male version designed for cable mounting. You can use it to create your own power cable for Arduino, ESP32 boards, routers, LED strips, or any device with a DC power input. The connector body is detachable; wires are attached by soldering, and the plastic cover is screwed back on to provide mechanical strain relief and insulation. Select the connector based on the size of your device's power input.

Specifications:

• Type: DC coaxial power connector (jack), male, for cable
• Max. load: 30 V DC / 1 A
• Contact resistance: ≤ 0.03 Ω
• Insulation resistance: ≥ 100 MΩ
• Wire connection: soldering (2 terminals – positive centre pin, negative sleeve)
• Material: plated metal contact + plastic body with screw cover
• Dimensions (outer × inner diameter):
  • 5.5 × 2.1 mm: the most common size – Arduino UNO/Mega, development boards, routers, LED power supplies
  • 5.5 × 2.5 mm: looks the same as 5.5/2.1 mm, but has a thicker centre pin – laptops, 3D printers, high-power adapters
  • 6.3 × 3.0 mm: larger connector for power supplies with higher current draw
  • 3.5 × 1.35 mm: small connector – cameras, small audio devices, small electronics

Package contents:

• 1× DC power connector for cable (depending on selected variant)

Note:

• Dimensions 5.5/2.1 mm and 5.5/2.5 mm are indistinguishable from the outside – verify the inner diameter of your device's power input before purchasing. An incorrect combination leads to poor contact or damage to the socket.
• Check the power polarity of your device. For most electronics, the centre pin is the positive pole (+).
• This product is not a standalone functional unit and may require professional installation.
• Product images are for illustrative purposes only and may sometimes differ from the actual appearance of the item. However, this does not change their basic properties.
