Description: Screw Terminals with 3.5mm pitch pins. Comes in 2 or 3 positions and have the really cool feature of slide-locking together to form any size you need (4, 5, up to 20 without problems). Rated up to 125V @ 6A. Terminal can accept 30 to 20AWG wire. 3.5mm/138mil pin pitch will not fit standard 0.1" perf boards but this is the most common pitch screw terminal.

  • What library part is this? Seems like M03/M03SCREW (SCREWTERMINAL-3.5MM-3), though the M03 section description says “Standard 3-pin 0.1” header. Use with straight break away headers", M03/M03SCREW doesn’t have anything more specific, and the description above says specifically that it doesn’t work with standard 0.1" spacing.
    Also: how does the pin spacing work on the board when these are locked together in pairs, triplets, etc. Do they form a continuous 3.5mm pin spacing, or is there an extra wide gap between the 3-pin units?

    • I know it’s a few years late, but in case anyone else has the same question… SCREWTERMINAL-3.5MM-3 does seem to be the closest part I could find in the Sparkfun Library, but if you’re planning to lock a few of them together, the borders do overlap significantly if you set them up with the correct hole spacing. When locked together, the pins do follow a continuous 3.5mm spacing. The top portion of the datasheet does a mediocre job of showing that by indicating the width of the block as [number of contacts] x 3.5mm, with the interlocking tabs protruding an additional 0.5mm. Unfortunately the lower portion under “P.C.B. LAYOUT” is rather misleading, the outline ecompases the entire width of the terminal, including the tabs. This would seem to indicate that you need 4.6mm between the holes of two adjacent blocks, but I assure you that will not allow you to snap them together, you’ll have about 0.6mm gap between the tab of one terminal and the edge of the next one.

      Lesson learned: Use 3.5mm spacing between all holes if you want to snap them together. You can use 4.6mm spacing between the holes of adjacent blocks and they’ll still solder in without interfering, but you lose the extra rigidity of having them all snapped together.

  • Will these fit on a arduino protoshield?

  • Please also sell the 2-pin variant of this. Having just the 3-pin ones limits the possible configurations. Also, I need to buy one to complete the last two pins on my Arduino Screw Shield.
