The SFSD-40-30C-G-19.69-DR-NDS is a double row, 40-position (2x20), high-density socket strip from Samtec's SFSD series. It features a 0.050" (1.27 mm) pitch, gold-plated contacts, and a shrouded body ('C' designation). The '30C' specifies the insulator height. The 'G' stands for gold plating on the contacts. '19.69' refers to the stack height in millimeters from the board surface to the top of the connector. The 'DR' signifies a double row configuration, and 'NDS' usually indicates a customer-specific or Samtec internal specification, often pertaining to packaging or a particular design modification.

Applications

• High-density board-to-board connections in electronic systems.
• Signal routing in compact devices.
• Medical instrumentation.
• Industrial automation equipment.
• Telecommunications and networking hardware.

Features

• 0.050" (1.27 mm) pitch for high-density interconnects.
• 40 positions in a double-row configuration (2x20).
• Gold-plated contacts for superior conductivity and corrosion resistance.
• Shrouded body for enhanced contact protection and alignment.
• Through-hole termination for secure PCB mounting.

Benefits

• Enables compact designs with high pin counts.
• Provides reliable electrical connections with gold-plated contacts.
• Protects contacts from damage during handling and mating due to the shrouded design.
• Ensures long-term performance in demanding environments.
• Offers a stable and secure connection to the PCB.

Additional Details

The SFSD series is designed for high-density applications requiring reliable and robust connections. The gold plating ensures low contact resistance and excellent resistance to corrosion, making it suitable for challenging environments. The shrouded body enhances the durability of the connector and aids in proper alignment during mating. The 'NDS' designator typically refers to a specific manufacturing process, packaging configuration, or internal Samtec specification, often tailored to meet specific customer needs. Mating connectors are typically terminal strips from the same series or a compatible series with the same pitch and number of positions.
