Pin Connectors (Dupont, Mini-PV, Berg)
Dupont connectors are used in electronics for making jumper wire connections. They are commonly used in breadboards and other prototyping tools. For example, a hobbyist building a DIY robot might use Dupont connectors to connect various sensors to a microcontroller.
People often call PCB pin strips, un-shrouded female PCB headers, and un-shrouded female plugs "Duponts". However these incredibly common 0.1" pitch, 0.025" square pin headers have acquired many different names such as “AMPMODU”, “Mini-PV”, and “Berg”.
History:
These connectors were first made by , which was founded in 1946. Berg was eventually bought by DuPont (the same company that makes chemicals) In 1993, DuPont sold to . DuPont now only makes the . In 1998, HM Capital Partners sold Berg to Framatome Connectors International (FCI), and in 2016, was FCI sold to Amphenol. Amphenol calls these connectors "Mini-PV Basics" Today, lots of other companies make the same connectors, and "DuPont" is now , just like Kleenex-for example, AMP rolled out its AMPMODU series based on this standard, before it was sold to Tyco. The dizzying set of sales has resulted in a confusing genealogy, and many of today's standards are not interchangeable.
Dupont Connectors
These are rarely used by hobbyists, but have a long history, originally starting production in 1950. This type of connector has often been used in higher-end applications, and can get a bit pricey.
The ’DuPont’-clone: the M20.
Note the small size compared to the integrated circuit-and the size of the IC itself. These connections fit easily inside of small devices.
Each type of connector pin is attached to the printed circuit board by soldering and then easily connected to other devices using proper cabling. But there’s a lot of variety, and not all components work well together. Wires must also be properly crimped down when being soldered to pin leads, and the quality of crimps can vary. The hobbyist may often find it necessary to do this themselves. If they do, they should be careful to strip the wire properly, and make the crimp with care. This will greatly improve the quality of the wire leads, adding longevity and performance to their builds.
