The prototypes has been built and tested. My only concern is that the since the female magnetic connectors will be located at fixed locations and the node that is always energized. It stays somewhat exposed until the male connector makes a contact with it to send the current through the tube......will it be in issue with UL? I have seen many power rails by electronic companies that are using this technology in power rails. Power rail has energized components exposed but since it low voltage, it wont cause an electric shock in case of a human contact but as soon as you place an LED strip on to the power rail housed by a magnet, it forces the LED strip to keep in tact and lights up the LED Strip.

Still not sure your exact usage but something else I thought of: the part that is powered should probably NOT be magnetic, lest it attract and hold metal trash like paper clips, pushpins, etc. The male part would be magnetic, the female (powered) part just metal. Dunno if its a UL thing, just something to keep in mind.

My first computer course was in Fortran and we submitted our programs on decks of punch cards. The IBM 360 we used had a hard drive the size of a La Z Boy which had a capacity of 64k.
Yes, that's a "k".

My first computer course (in high school) was straight machine language on a North American Rockwell Autonetics division Recomp 2.
The terminal was a Friden Flexwriter (with paper tape) and main memory was a 10k word fixed disk. It also had 10 transistorized registers for frequently used values. One of the optimizations for programming was putting variables at an address where they would come around on the disk as soon as possible after the instruction that used them.
Halfway through the course the company went out of the computer business and the salesman who was teaching the course lost his job.
My first college computer class was in Gotran (a single pass load an go compiler with all of 26 named variables, a to z) on the IBM 1620. A computer that needed its addition and multiplication tables loaded into memory from punched cards before it could do arithmetic.

The first hard drive I had was 1MB. The last one I bought was 2 TB. Factor of two million.

And it probably cost a lot less!
Thanks for the tip and yes you are correct only the male housing should contain magnets. I have attached the picture, i hope it helps.
What i am concerned about is the opening of female housing which doesn't have a magnet but as you can see it does have a constantly energized materiel which is internally wired through an AC to DC Adapter

What about designing a snap-cap style cover to plug the port when not in use? The sample I linked to may not be exactly what's needed but conveys the general idea.
Client didn't like the idea of having a snap-cap otherwise that would have been ultimate solution. We deal with cosmetic industry and appearance is a huge factor...

Spent many days and nights typing BASIC code into my Timex Sinclair, straight from a magazine. Then saving it to the cassette tape. I tried explaining it to my son the other night, and about text based games. I showed him Zork, his interest level was minimal.
