5mm DC Jack Female Connector with Wire

Prototyping and Engineering Tips from Robogears

• Polarity Check: CRITICAL: Most DC adapters are "Center Positive," meaning the inner pin carries the Positive (+) voltage. However, always use a multimeter to verify that the Red wire is connected to the center pin of your specific connector before connecting it to sensitive electronics.

• Mounting in Enclosures: If you are building a 3D-printed or plastic project box, you can secure this pigtail using a cable gland or a zip-tie "strain relief" inside the box. This prevents the wire from being pulled out if the power cable is accidentally yanked.

• The 2.1mm vs. 2.5mm Rule: This jack has a 2.1mm center pin. While a 2.1mm male plug will fit perfectly, a 2.5mm male plug (often used for high-wattage laptops) will not fit. Conversely, putting a 2.1mm plug into a 2.5mm jack will result in a loose, intermittent connection.

• Parallel Powering: You can use multiple female pigtails in parallel to distribute power from a single high-current source to multiple independent modules. Just ensure your main power supply can handle the total combined current of all connected devices.

• Soldering to Terminals: When connecting these leads to a terminal block, avoid over-tightening the screws, which can shear the small copper strands. If possible, crimp a bootlace ferrule onto the wire ends for the most professional and secure industrial-grade connection.

Package Includes

• 1 x 5mm DC Jack Female Connector with Wire (Pigtail)

Disclaimer: Intended for low-voltage DC applications only; do not use with AC mains electricity. Ensure the total current draw does not exceed 5A to prevent overheating the wires. Always double-check the polarity of your power adapter before plugging it into the jack to avoid permanent damage to your circuit.
