Parts Express 2.5mm Panel Mount DC Jack is rated 4.5833 out of 5 by 12.
Rated 1 out of 5 by from Does not fit 120-052 Power Supply PlugI bought 5 of these and only one worked with the 120-052 Power Supply. They fit too loose and the p/s plug comes out easily. Both state they are 2.5 mm x 5.5 mm. I had to source a plug locally to finish projects.

Rated 5 out of 5 by from Perfect little DC JackThis 2.5mm Panel Mount DC Jack is perfect for some really neat DIY projects. I have bought a couple and mounted one on the outside of a bookshelf speaker, leading to the Dayton DTA-2 Class T Digital Audio Amplifier Module, inside the speaker- making it a self powered unit. I made myself a charging station for a cell phone, an iPod, a Bluetooth receiver and a camera with another. Really cool little jack with 1001 uses.

Rated 5 out of 5 by from Great DC JackThe DC jack on my laptop broke, and I wanted to be sure that what I replaced it with wouldn't break on me so that I wouldn't have to take my laptop apart again. It installed very easily, and it works great! It looks a little goofy having a panel mount DC jack on my laptop, but as long as it works I'm happy with it, and so far I haven't had any problems.

Rated 5 out of 5 by from That Third TerminalJust as an FYI, that third terminal is used as a battery bypass. So without the power being plugged in, you can used the battery if it is connected, and plugging in the power supply will disconnect the path to the battery and allow the power supply to take over.

Rated 5 out of 5 by from Well made, tight fitting DC jack!Very well constructed DC power jack. The split center pin makes for a good tight fit for the plug, providing a very good electrical connection that can't easily be pulled loose. The metal ring surronding the threaded mounting portion makes for super sturdy construction that won't easily be broken if the plug is bumped or pulled sideways.I'm a repeat customer on these!

Rated 5 out of 5 by from Works!Using these to mod my Rock Band instruments. Got tired of buying batteries all the time and my rechargeable ones are for cameras and the bodies are tight in the drums/guitars. Works good and they are cheap. Not sure why there is a 3rd prong on the plug I couldn't get cont. to either the power or ground with volt meter? So I just broke that one off.

Wiring the by-pass

In one of the reviews someone states that the 3rd terminal is used as a battery by-pass. How would something like that be wired? Thank you.
Asked by: TenTwelve
Let us call the center pin terminal 1, this will (typically) be the positive (+) connection. The other two terminals (for the sake of argument) will be common (-), and switched. Simply use a multimeter to test for continuity on the various terminals. The "third" terminal will have continuity to the (-) terminal when the DC plug is disengaged. One would use this terminal to switch the common for the batteries on and off.

is this the same diameter as the jack on Guitar effect pedals, ie, Boss etc?

Asked by: Venturas
not sure but i do know that 2.5mm is the diameter of the center pin of this connector. this is the same as most flat screen computer monitor power plugs if that helps.
