Screw Terminal Block - 3.5mm Pitch (3-Pin)
£0.99 ex VAT
Screw Terminals with 3.5mm pitch pins. They have the really cool feature of slide-locking together to form any size you need (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.
SFE Eagle Library has this part!
Please note: These may fit standard perf boards if inserted diagonally.
