The SFSD-40-28-G-03.75-DS-NDX is a Samtec SFSD series, high-density socket strip. It features a 0.050" (1.27 mm) pitch and a double-row configuration with 40 positions (2x20). The 'G' indicates gold plating on the contacts for optimal conductivity and corrosion resistance. The '03.75' specifies the stack height in inches, measured from the board surface to the top of the connector. The 'DS' indicates a double shrouded design for enhanced pin protection and alignment. The 'NDX' usually signifies a specific design feature or a customer-specific modification, often relating to packaging or manufacturing processes.

Applications

• High-density board-to-board connections in electronic devices.
• Data and signal transmission in compact systems.
• Medical devices requiring reliable connections.
• Industrial control systems where space is limited.
• Telecommunications equipment for signal routing.

Features

• 0.050" (1.27 mm) pitch allows for high-density interconnects.
• 40 total positions in a double-row configuration (2x20).
• Gold-plated contacts for superior electrical performance and durability.
• Double shrouded design for increased contact protection and secure mating.
• Through-hole termination for robust mechanical connection to the PCB.

Benefits

• Enables compact and space-saving designs in electronic assemblies.
• Provides reliable signal transmission with gold-plated contacts.
• Minimizes the risk of contact damage during handling and assembly due to the shrouded design.
• Ensures long-term performance and reliability in harsh environments.
• Offers secure and stable connection to the PCB with through-hole mounting.

Additional Details

The SFSD series is known for its robust construction and high-performance capabilities. The gold plating ensures low contact resistance and excellent resistance to corrosion, making it suitable for demanding applications. The double shroud provides enhanced protection and facilitates accurate alignment during the mating process. The 'NDX' designator likely specifies a unique customer requirement or internal Samtec specification, often related to packaging or special testing. Mating connectors would typically be a terminal strip from the same series or a compatible series with the same pitch and number of positions.
