Due to the different specifications applied in electronic products, pin headers are also divided into various models and specifications. The electronic industry classifies pin headers according to certain standards:

  1. Based on the pitch, they can be roughly divided into 0.8mm, 1.0mm, 1.27mm, 2.0mm, 2.54mm, 3.96mm, etc.
  2. The number of rows can be single-row, double-row, triple-row, quadruple-row, etc., with quadruple-row being the most common nowadays.
  3. The pins can be classified as straight pins, bent pins, SMT (Surface Mount Technology), and also by their size.
  4. Dimensions are classified based on the external dimensions such as length, width, thickness, and pitch.
  5. Based on the packaging, they can be categorized as surface-mount SMT (including horizontal and vertical mounting) or through-hole DIP (including straight and angled insertion).
  6. Installation methods are categorized as 180° using “WV,” 90° using “WR,” and SMT using “S.”
