Solder dupont connector1/6/2024 I also like the flush headers, as they fit into a lot of through-hole configurations with a bit of wrangling.and work great. I like the jst wire-to-board stuff.they seem to survive many many pluggings and unpluggings, so I use them on the dev boards. I hate the little buggers, and they fail all the time for me, or it takes me hours to do just a few wires. On the JST-JWPF seems to be fine as long as *I'm* not the one crimping them. The 3rd party tools aren't quite as nice, but they work just fine. It might be odd, but we have found much better reliability with the JST connectors and pins. We have reduced our failures by making a jig that holds the wire and the crimp entirely inline, but building that jig probably cost as much as a pneumatic crimper. They are fine for machine crimping, but we have a failure rate over 50% with hand crimping these. MX and MXP connectors are a pain in the ass. I like the ones with the little barb.you push it through your solder hole, and it holds the wire in place while you get your heat on. If you have stuff that gets yanked on, use these. They are crimps that reinforce the wire at the solder. My favorite one is made from a ground down bicycle spoke. Buying or building a pin-set tool is vital for this. Most of the errors we see here are from improper pin orientation or setting. We use nano in about 50% of our non-waterproof stuff. The Nano-fit are also good, but the 3rd party crimpers are crap. Also, the cheap tools for crimping these are superior to the Molex branded tool (which suffers from slow pin loading and requires ultra-precise alignment.easy to mis crimp stuff) as well as being 1/8 the price The dual crimp (wire and insulation) results in connections that are plenty robust for multiple uses. The Molex Mini-Fit stuff, while a bit large, is very reliable. We use several types of connector (crimped) at work. Soldering a connector contact designed for crimping increases the likelihood of the wire breaking at the connector body. The improvement gained by soldering was simply due to poor inital practice. But those centered around improper tooling or methods. A good example are the numerous MTA failures with the Klee kit. While it may be true in the isolated case, it is not good practice. Suggest taking that with a grain of salt. This statement is sure to result in anecdotal reassurances that soldered MTAs and other crimped connectors actually increased their reliability. While soldering a connector designed for crimping is often possible, you will almost always reduce its lifetime and reliability over a proper crimped connection to stranded wire. If youre making things for pay, get the right tools. See ARP 2600 for example of this useage on the PCB power pins using Molex KK156 connectors and mill max round pins.Īgree with the prior post that decent import crimp tool for 'DuPont' style connectors will work fine for most DIY crimped connectors, and only cost around $30. 100" spaced wire leads of the pot itself you do NOT want to use MTA-100 series as these have limited pin depth due to their IDC contact construction.Ī molex KK-100 with crimped pins -which can be soldered instead- will allow the pot pin leads to slide past the contact and exit the connector body as far as required. If you're planning to put the connector on the. Originally created by the AMP connector company, which has now become part of another company and operates under a new name. MTA-100 and MTA-156 are IDC connector families. They make hundreds of different connector types.
