content: Hello everyone, I'm building a project that uses one of these mike connectors (that's how they are known here in Brazil). They are basically 5-pin 240 degree DIN connectors with threads so that the plug can screw into. I want to solder one of these directly into my PCB so that it can be screwed in to the panel later and be used as a convenient support for the PCB. Are there any libraries available for this part or at least somewhere I can get a drawing file with the dimensions so that I can make the footprint myself?This is how it looks like:

content: They are actually microphone sockets. Look for a PDF data sheet and it should have the footprint dimensions to make your own. Eagle should have some under con-hirschman MAB5SV or something.

content: Be carefull though, these are not made to be soldered directly on a pcb.If you look at the mechanical ring construction that is to withstand the pull out forces.If you do not have any other mechanical strain relief, that full force will go onto the soldered pcb contacts, which is not going to last.There are alternative connectors that are made for pcb mounting see pictures.

content: Quote from: wasyoungonce on August 17, 2017, 10:46:01 pmI looked at that footprint, but it appears to be for the 180 degree type, not the 240 degree like mine.Quote from: Kjelt on August 18, 2017, 09:24:04 amThanks very much for the input, but the connector will be screwed on to the front panel using the ring, then soldered to the PCB, so that it will be fully mechanically supported by the front panel and will just provide a nice support to raise the PCB from the front panel, so any forces applied to the connector are never going to stress the solder connection.

content: I would love to make my own footprint, but the problem is that I can't find a drawing with the dimensions and spacing of it anywhere.

content: Is the contact arrangement equivalent to DIN EN 61076-2-106? Would this information help?http://www.mouser.com/ds/2/18/40_c091_abd_e_20140411-321027.pdfhttp://www.lumberg.com/wp-content/uploads/lumberg_03_layouts_emc.pdf

content: Looks like they match the one I have quite nicely. Thanks very much for sharing these documents. I will use the dimensions from the Amphenol catalog to build the footprint:I noticed that in the plug the bottom pins are bit closer to the center of the connector, of course this is because they are 60 degrees apart from each other as shown in the Lumberg datasheet:Is there a way to do something like a circular pin placement in Eagle? So that I can say the circle has a radius of 3.5mm (from the Amphenol data) and a spacing of 60 degrees to get a perfect footprint?

content: What you're asking is a machinist's problem, to be solved with machinist's calculators. Use this Bolt Circle calculator (http://littlemachineshop.com/mobile/bolt_circle.php) to determine the X-Y coordinates of the centres of each of your six pins. Input your # of pins, the bolt circle diameter from the Amphenol drawing, the pin diameter and the degree of separation (60). It does the rest. Then produce your footprint centering the pin holes where the calculator says.

You can then lay down redial angle dimension line (from that centre point) that show the angle measurement that the pin is on. Obviously the pin is on the intersection of the PCD and radial line. You can also use maths, sine and cos and vectors but I find it easier to use a small grid a radial line and measure.The dimension data info can be removed or edited ("edit properties") as wished..eg: to edit that a dimension exactly points to a line.
