1. Basics

• Type: Double row inline header pin header with 2 rows of 2 pins each, totaling 4 pins.
• Application: Widely used in electronic devices as an electrical connection interface between circuit boards and other components.

2. Structural Features

• Double Row Design: Offers twice the pin count of a single-row connector, suitable for applications requiring more connection points.
• Inline Configuration: Enables direct insertion into holes on circuit boards for simple installation.
• Compact Structure: With two rows and a moderate pin count per row, the overall structure is compact, saving space.

3. Technical Specifications

• Pin Pitch: Common pin pitches include 1.27mm, 2.0mm, 2.54mm, etc., depending on the product model and specifications. The pin pitch affects connector density and installation accuracy.
• Materials:
  • Contact Material: Typically copper alloy or copper plated with gold, silver, or other metals for excellent conductivity and corrosion resistance.
  • Insulator Material: Made of high-temperature, flame-retardant plastic materials such as nylon (PA) or polybutylene terephthalate (PBT), ensuring connector stability and safety.
• Electrical Performance:
  • Current Rating: May vary based on product specifications but generally meets the needs of typical electronic devices.
  • Voltage Rating: Also determined by product specifications, adhering to industry standards or customer requirements.
  • Contact Resistance: Low contact resistance ensures accurate and stable signal transmission.

4. Application Areas
