I bought a 180-degree 5-pin DIN chassis-mount socket dirt-cheap for a project, but I saw that it looks quite different from the MIDI outs on my MIDI gear; I did some research but couldn't find any info on MIDI plugs being any kind of specialized DIN shape, just 5-pin 180-degree DIN.
I just ordered another chassis-mount socket from UK, advertised on their site specifically as being for MIDI, but it's the same as the cheap one I got before, and doesn't appear to be the same as on my gear. I currently don't own a cable, so my own tests are pending. But when they say MIDI is 180-degree 5-pin DIN, is it really exactly the same or is there some other specification that needs to be made between different layouts of 180-degree 5-pin DIN? Diameter of the semicircle? Size and shape of the aligning nub?
I can easily believe no one has ever actually ordered this product and tried to use it since the UK online store has been running! What I can't believe is that this information doesn't exist anywhere within Google's reach. It's out there somewhere.

"DIN" is the name of the German standardization body; all the relevant dimensions are exactly specified in DIN 41524, or nowadays IEC 60130-9.

The cable's connector has five simple pins:

There are different ways of aligning the springs that hold these pins:
MIDI jack MIDI jack

However, what matters are the positions of the actual pins and holes, and those are always the same:

  • \$\begingroup\$ Thanks for the direct answer! May I ask if you found this info online, and where? Or do you know from your experience? So, when I pick up that cable next week, if it doesn't go into the holes of the panel mount connector I bought, I can complain to Hobbytronics UK. \$\endgroup\$ Apr 13, 2016 at 18:36
  • \$\begingroup\$ This is just from various connector datasheets, found via Google. \$\endgroup\$

Easily found through Google, the current MIDI spec's are available here: of which page 3, excerpted below, describes the connectors:

Following up on their Switchcraft link leads to:

Where you'll surely find what you need.

  • \$\begingroup\$ Thank you, and yes, I read that already, but this does not answer the question of whether all 5-pin 180-degree DIN connectors have the same dimensions - i.e., the distances between the pins, the radius of the circle in which they are positioned, etc. I asked CL where he/she got the info, still waiting to see. \$\endgroup\$ Apr 14, 2016 at 16:06
  • \$\begingroup\$ In fact, most stackexchange answers could probably also be found by following links from links from Google results, sifting through official standards documents, etc., but I still think stackexchange has a place that Google can't take in the exchange of information. \$\endgroup\$ Apr 14, 2016 at 16:20
  • \$\begingroup\$ @ChuckkHubbard: Part 1. If you're still waiting, it appears you missed CL's reply of 11 April, where he cites his source as DIN itself, with his reference being: "DIN 41524, or nowadays IEC 60130-9." If you want to pay to download the document it should give you everything you need. If you choose not to, Switchcraft's site can get you started by giving you the bolt circle for the 180\$\degree\$ 5 pin female. Part 2 follows... \$\endgroup\$

  • \$\begingroup\$ @ChuckkHubbard: Part 3: On top of all of that, you haven't stated what relationship exists between the [your] MIDI equipment you made allusion to and your "project", nor have you responded to requests asking for photos of your equipment from which dimensional assessments might be made in order to help you on your way. Instead, you seem to take every opportunity to demur, slight, and prolong your stay. Why> \$\endgroup\$

  • \$\begingroup\$ @ChuckkHubbard : Part 2. Since the male will have to plug into it, all you'll really have to do once you decide what it is you want to plug into what, is to figure out the diameter of the male pins. But, since that's all been figure out beforehand, it's moot. \$\endgroup\$
