The "half-pitch connector" is a product that has been on the market for over 30 years and is primarily used in industrial equipment. Half-pitch refers to the pin spacing being half that of full pitch (2.54mm pitch), which is 1.27mm pitch, hence the name half-pitch. The adoption of inches is said to be due to the fact that connectors originated in the United States. However, recently, the world standard of millimeters (mm) has become the basis. Full pitch connectors are often standardized products like DIN or MIL, while half-pitch connectors tend to be more proprietary products from various companies. *For more details, please refer to the PDF document or feel free to contact us.*
