Amphenol T821 Series Right Angle Box Header, 2.54mm, 26 Way

The Amphenol T821 Series Right Angle Box Header is a robust and reliable wire-to-board connector designed for precision electrical connections. This 26-way, 2-row connector features a compact right-angle design, making it ideal for applications where space is at a premium or where a perpendicular connection to the circuit board is required. With a standard 2.54mm pitch spacing, it ensures compatibility with a wide range of components and headers.

Constructed for durability, the connector utilises gold-plated phosphor bronze contacts housed within a black, glass-reinforced thermoplastic insulator. This combination provides excellent electrical conductivity, corrosion resistance, and long-term mechanical stability. The connector is shrouded for added protection, helping to prevent mis-mating and offering strain relief for the wire terminations.
