Description
The 2.54mm Female SIL (Single Inline) Header is a versatile connector used to interface with electronic circuits. It features a row of female sockets that match a 2.54mm (0.1 inch) pin spacing, making it suitable for use with standard male pin headers, ICs, and modules . This 40-pin version provides ample connections for complex projects, and its single-row configuration and right-angle design make it ideal for space-constrained PCB layouts . It is commonly used in circuit boards for connecting various electronic components, providing a reliable connection in a compact and space-efficient form.
Key Features
- 2.54mm (0.1 inch) pitch: standard spacing for breadboards, Arduino, and most development boards
- 40 pins: ample connections for complex projects and multi-module setups
- Female connectors: for interfacing with male pin headers, ICs, and module pins
- Single row configuration: straightforward alignment and easy soldering
- Right angle design: suitable for low-profile installations where vertical space is limited
- Gold-plated contacts: enhances conductivity and resists corrosion for reliable connections
- High-temperature plastic body: withstands soldering heat and provides good insulation (rated up to 180°C)
- Suitable for PCB mounting: easy integration into custom boards and prototypes
- Reliable and durable connection: designed for repeated mating cycles (typically 50–100 cycles)
