Harwin Archer M52 Series 20-Way SIL Vertical Pin Header

The Harwin Archer M52 Series 20-Way SIL Vertical Pin Header is a high-quality, single-in-line (SIL) connector designed for reliable board-to-board connections in demanding applications. This vertical header features a robust black polyamide (nylon) 6T housing, rated UL94V-0 for excellent flame retardancy and thermal stability. The connector utilises gold-plated brass contacts to ensure a low-resistance, corrosion-resistant connection, enhancing both signal integrity and long-term durability.

With a compact contact pitch of 1.27mm x 2.54mm and a 4mm mating pin height, this header offers a space-saving solution for high-density PCB layouts. The through-hole straight termination provides a secure mechanical and electrical bond to the printed circuit board, suitable for wave soldering processes. It is engineered for a contact rating of 1A, with a maximum contact resistance of 20mΩ and a minimum insulation resistance of 1000MΩ, guaranteeing consistent performance.
