Dupont 2.54mm Pitch Connector: Features, Applications and Advantages
Product Overview
The Dupont 2.54mm pitch connector is a widely used standardized interconnect solution, primarily for wire-to-board and wire-to-wire connections. Named after its 2.54mm (0.1 inch) pin spacing, this connector has become an ideal choice for electronic prototyping, industrial control systems, and consumer electronics applications.
Key Features
（1）Standardized Design
Uniform pitch: 2.54mm (0.1 inch) spacing compatible with most PCB layouts and breadboards
Multiple pin configurations: Available in single-row (1xN) or double-row (2xN) arrangements with flexible pin counts (typically 2P to 40P)
Versatile combinations: Offers male/female headers and terminals for various connection needs
（2）Reliable Electrical Performance
Current & voltage: Rated for 3A current and 250V, suitable for low-voltage signal transmission and low-power supply
