XLR

Basics

• An electronic connection standard, in similar widespread use to USB , 12v Barrel Jacks , and MIDI
• Is often lockable, and enviroment hardened
• Available in:
  • Two-Pin
  • Three-Pin (Most common)
  • Four-Pin
  • Six, and Seven Pin are less common, but DO exist if need be
• "Bundled" cables are available for large amounts of cables ( Cable Managment is the only advantage
  • With these, you use either a "frayed/split off" end, or some short cables to connect the bundle to your devices, and use the solid bundle as the long distance element
    • These (outside of power applications) are largely replaced by ArtNet and similar protocols (These use standard lan so it can be as simple as into the box, then a single ethernet, or even a wifi connection

Sourcing

Two Pin

• Seem quite rare, and a 3 pin xlr could work fine, just would need other pcb side wiring (don't use 1 pin)
• MAY be cheaper for cable though due to less total copper etc
• Two Pin Socket Source ~2.00 USD Each, comes in packs of 5 or 10) not pcb, but could work with 3d printed case

Three Pin

• Amazon Source for Metal Option
• Amazon Source for Cheaper Option
