Here is a list of crimp contacts for part 455-2266-ND which you will need to select the proper contact by the size wire gauge being used. Shrouded headers on radial-tape are also available. Header pins are round and reflow-treated, which provides low insertion force. ![]() Header wafer is made of solder crack preventive material, glass-filled PA66 nylon. Crimp contacts are not included with the inline connectors so be sure to include them with your order. Secure locking device prevents accidental disconnection. ![]() Here is an option for a 2 position header, part 455-2247-ND, scroll down and you will see the inline mate to this would be part 455-2266-ND. This handy chart is intended to help with. Most people don’t have to deal with these things on a daily basis, and one look at the back of your PC or the side of your laptop can sometimes be a bit confusing. These are wired with a JST connector that is compatible with the Modular. When looking for a mating connector scroll towards the bottom of the page to the section that lists the “Mating Products” and select the option that best suits you’re needs. The world of computers has a staggering array of cables, adapters, and ports in a variety of shapes, sizes, and colors. Nominal voltage chart for 52V Li-Ion Ebike batteries showing the percentage. These lists show the vertical and right angle versions along with the option to select tin or gold contacts. These numbers, XH2.54-2 or XH2.54-3 are referring to the XH 2 position headers or XH 3 position headers. These are actually the XH series of connectors from JST available here at Digi-Key, XH Series connectors Often what you will see in the BOM (Bill of Materials) listed for a board will be numbers like JST XH2.54-2 or JST XH2.54-3 which is not the actual part number you would use when ordering, for example purposes you will see I used the -2 and -3 suffix which is simply calling out the number of positions on the header. Purchase Parts 720 PCS JST-XHP Connector Kit - $10.99Ģ2 AWG Stranded Wire - $14.99 Tools (Optional) Wire Stripper Tool - $4.XH2.54 connectors from JST: We have several inquiries about this connector since it is a commonly used pin header on power supplies, eval boards, etc. But for hobbyists doing frequent upgrades or those running home based printer farms, we can certainly benefit from crimping our own JST connectors as needed. ![]() For a one off weekend project, this probably isn’t worth the expense of parts and tools. Better yet, they are easy enough to make on demand. I could just splice the new fan to the original fan’s wiring, or solder the wires to the board, but I prefer to keep my setup clean and professional.Īfter some Google research, it turned out almost every 3D Printer board uses JST Connectors, the XH series to be exact. Sure, there were perhaps better options on the table that would cost less upfront. This conundrum introduced me to the art of crimping my own JST Connectors. It came with a small, 30mm cooling fan and plenty of wiring length was included, but it didn’t have a plug for the board. Here is a general guideline for the continuous and burst current ratings of some commonly used connectors: JST connector: 5A (10A) 2mm bullet connectors: 20A (40A) XT30: 30A (60A) XT60: 60A (180A) While it’s tempting to overcompensate and use larger connectors, it’s not always necessary and can add unnecessary weight to your drone. When I first started down the rabbit hole of 3D Printer upgrades, one of my earliest projects was installing a V6 hotend on the Anet A8.
