![]() Headers, eliminating the need for customers to make major revisions or investments in their applications. There is a plastic locator at the rear to hold contacts in place while crimping. Above is a close-up of the official tool. The current tool is 63811-8200, again made by Pressmaster Sweden, priced at around 300. Mini-Fit TPA2 Receptacles are backward compatible with Mini-Fit Jr. The contacts, regardless of brand are all of the same design, so looking at Molex’s tool is relevant. Mini-Fit TPA2 Connectors prevent end-product failure by offering terminal position assurance (TPA), which reduces terminal back-out by providing locking redundancy. The impact of terminal back-outs can result in liability costs to manufacturers and harm to individuals. Incorrectly assembled connectors can lead to terminal back-outs, causing end-product failure. Furthermore, they feature flanges that help “gather” the mating receptacle for more accurate mating. Mini-Fit BMI Connectors allow misalignment and provide up to 2.54mm of float between mating surfaces for easy blind-mate connections. and Mini-Fit Plus Connectors are compatible with each other, including with Mini-Fit TPA2 and Mini-Fit BMI Components, bringing flexibility to the toughest design dilemmas.Ĭustomers with blind mate applications require connectors that make assembly easier, protect against mis-mating and prevent potential damage to terminals. To meet these needs, Mini-Fit Jr., Mini-Fit Plus, Mini-Fit Blind-Mate Interface (BMI) and Mini-Fit TPA2 Connectors offer polarized housings with isolated terminals, positive locks and low-engagement forces. Provides excellent support for the rubber cap that mounts around the back of the housingĪllows for accurate mating to standard Mini-Fit 4.2 Power ConnectorsĪ wide range of OEMs require high-current, high-density power connectors that also support design flexibility.

It is too advanced for me, but I did pick-up a few ideas about ground planes (tip #6 from the video).Enables operator to mate connectors in hard to reach areasĮnsures header and receptacle cannot be mismatedĮasy to operate thumb latch assures connectors are fully mated Mini-Fit BMI Connectors allow misalignment and provide up to 2.54mm of float between mating surfaces for easy blind-mate connections. Tonight, I saw this video: It describes common PCB errors. In effect this thing has saved me from buying an oscilloscope for my simple little bench. Power Profiler Kit II has been indispensable in watching power usage and seeing into the details of the radio transmission. Not only is the signal density displayed on the software (SDR#) but so is the frequency. Using this I can clearly discriminate between effective 433 MHz transmitters and bad ones. With the help of Andreas Spiess explanation of IQ transformations, I learned about Software Defined Radios and I bought one (RTL-SDR). Software Defined Radios for signal analysis. This library of information (Thank you NeverDie and others) has been so helpful in my hobby developments. It has been a long time but I’ve learned a few things that I wanted to share. Used correctly, either the 28B or the 2549 will produce identical results. ![]() If I hurry the crimp cycle with any appropriately-sized crimp tool, I'm going to get a bad crimp, so bear that in mind. If you see somebody in an online video using a crimp tool and obtaining satisfactory results, keep in mind that that person's circumstances will not necessarily be the same conditions of use for you. There is no single crimp tool for all terminal types, and what works well for one individual may not necessarily work well for you, and that has a lot to do with wire type, brand of terminal, tension setting of the crimp tool being used, the level of polish on the dies in use, and probably most notably, the speed with which the crimp cycle is executed. The AP-153045 is too large, being designed for Anderson Power Pole connectors, and the IWS-3220 is just a bit small for such duty. The SN-28B, as well as a couple of the other crimp tools, will crimp the terminal types you have mentioned, as well as the SN-2549.
