RS Pro 7mm Straight HeadersOur own range of RS Pro PCB headers are unshrouded headers with 0.64mm square pins and 7mm pin height. They feature a 2.54mm pitch and are made from UL94V-0 black glass filled PBT. The contacts are plated with a pure and bright tin. Our RS Pro PCB headers are a through-hole solder termination for easy and permanent use. These PCB headers make great use in board to board, wire-wrap or programming applications.PCB Headers are used to connect two PCB boards together. This makes it highly efficient by not having to solder the board together or wire them and will save you time. It also makes it very easy to remove the second board if anything fails. Features and Benefits: • Current rating of 1A • Can be snapped to get your desired length• 0.64mm square pins for general universal connections • PCB Headers are brilliant for prototyping & permanent solutions• Faster and efficient of connecting boards and wires. • 7mm pin height Need different sizes?Dimensions are AxB (Above x Below)Size 1: 251-8301, 251-8373 3.0mm x 4.6mmSize 2: 251-8317, 251-8389 4.3mm x 2.7mmSize 3: 251-8339, 251-8395 5.7mm x 7.6mmSize 4: 251-8345, 251-8402 5.7mm x 12.7mmSize 5: 251-8632, 251-8648 7.0mm x 3.0mmSize 6: 251-8351, 251-8418 12.7mm x 3.1mmSize 7: 251-8367, 251-8424 14.7mm x 2.9mm2.54mm PCB Connector RS RangeA large variety of connector options, to cover the majority of board-to-board, bussing and programming requirements.
