We sell a crimper that can be used with these contacts, but many crimpers designed for small uninsulated contacts will work as well if you have already have something in the toolbox. TARGET SIDE The JTAG connector is a 20 way Insulation Displacement.

If contacts don’t want to stay in the housing, the plastic tab can usually be pressed down a bit to help lock the contact in place. If this tab is lifted slightly, the contact slides out. There is a plastic tab that locks the contact in place. if you decide you want to change from individual jumpers to one that has a 4-pin housing for hooking up to a sensor for instance, you can easily pop the single housings off and pop a 4-pin housing on. On multi-contact housings you can even mix contacts in the same housing in order to key it.Īnother nice feature is the housings are also very easy to get contacts in and out of unlike most housings. One nice feature is that the same housing can mount either male or female contacts making them flexible in their application. They are also handy for making custom cables for connecting sensors and similar peripherals. This means that when the wire is correctly and precisely positioned in the pin, the optimum wire-strip length is only 0.10 in (2.5 mm). Fits standard Dupont style 2.54mm (0.1″) male and female pinsĭupont style connectors are the ubiquitous connectors used for making solderless breadboard jumpers as they come in both male and female contacts that mate well with 2.54mm / 0.1″ standard male and female headers as well as solderless breadboard contacts.īesides making custom jumpers, many items that are not solderless breadboard compatible can be made compatible by soldering wires to them and adding these connectors. The figure above shows the anatomy of a Dupont pin.It is seen that the total length of wire going into the pin should not exceed.KEY FEATURES OF DUPONT 2.54MM CONNECTOR HOUSING 4-PIN: Qty 10 – Dupont 2.54mm Connector Housing 4-Pin.These Dupont style 2.54mm connector housings are used to make custom jumper cables for solderless breadboards or to go between male and female headers that are on standard 2.54mm (0.1″) centers.
