Female Pigtail 5.5x2.1mm

ID: 3031_0

A convenient way to plug your power supply into any circuit. 5.5x2.1mm female connector.


Replaced by the CBL4209_1 – Female Pigtail 5.5x2.1

The pigtail is a good way to connect a power supply into your circuit, assuming your power supply has a 5.5x2.1mm connector. This is handy when wiring up sensors that require +12V. Instead of cutting the plug off your power supply, you can solder the pigtail cable into your circuit, and plug the power supply into it.

Note: The white wire is positive and the black wire is ground, assuming your power jack is center-positive. (All Phidgets products use center-positive power jacks).


All the power supplies that Phidgets sells are compatible with this pigtail.
