DuPont Connectors
DuPont Connectors are a style of small, 2.54 mm‑pitch electrical connectors commonly used in electronics prototyping for making quick, solder‑free wire‑to‑board or wire‑to‑wire connections. They consist of a plastic housing and metal crimp terminals (male or female) that can be combined into single‑ or multi‑pin configurations. These connectors are popular in breadboards, Arduino/Raspberry Pi projects, sensors, and DIY circuits because they’re easy to assemble, inexpensive, and reusable.
The connector style commonly referred to today as a “DuPont connector” traces back to the Berg Mini‑PV family, introduced in the 1950s by Berg Connectors, a company that later became part of DuPont and later Amphenol. The Berg Mini‑PV design used a 2.54 mm (0.1") pitch and featured a brass contact body with a beryllium alloy spring—an early, precision‑engineered wire‑to‑board connector.
Today, DuPont-style connectors can be found from the following series / manufacturers:
- Amphenol Mini-PV (the official, expensive, and uncommon "DuPont Connector")
- Harwin M20
- Harwin M20 clones
