High Current 20A 300V PCB Mount Screw Terminal Blocks for Aerospace and Railway

The SY825-8.25mm PCB screw terminal blocks are high-quality electrical connectors designed for reliable connections in demanding industrial environments. These terminal blocks feature a robust construction with brass pins and PA66 UL94V-0 flame retardant housing, ensuring excellent performance and safety.

With an 8.25mm pitch and support for wire sizes from 22-14AWG (0.08mm² to 10mm²), these terminal blocks provide versatile connection options. The M3 zinc plated steel screws offer secure wire clamping and high contact pressure, while the brass pin headers ensure optimal conductivity.

The terminal blocks operate within a wide temperature range of -40°C to +105°C, making them suitable for various environmental conditions. They can withstand soldering temperatures up to +250°C for 5 seconds during PCB assembly.

Available in multiple pole configurations from 2P to 24P, these terminal blocks are commonly used in aerospace projects, industrial automation, railway systems, and power distribution applications. The black housing provides a professional appearance while the standardized 8.25mm pitch ensures compatibility with various PCB designs.
