The DW-32-20-G-T-811 is a board-to-board connector from Samtec Inc., part of their DW Series of discrete wire connectors. These connectors are designed to provide a reliable and space-saving solution for stacking PCBs. The DW series is known for its low profile and high density, making it suitable for applications where space is limited.

Applications:

• Board Stacking: Connecting multiple PCBs together in a stacked configuration.
• Mezzanine Connectors: Providing a connection between a main board and a daughter card.
• Industrial Automation: Connecting control boards and I/O modules.
• Telecommunications Equipment: Linking PCBs in networking and communication devices.
• Medical Devices: Interconnecting boards in diagnostic and monitoring equipment.

Features:

• Number of Rows: Two rows of contacts for increased density.
• Pitch: Typically a fine pitch (e.g., 0.050" or 1.27mm) for space efficiency. Specific pitch is dependent on series but is a key characteristic.
• Contact Material: Gold-plated contacts for reliable electrical performance and corrosion resistance.
• Insulator Material: High-temperature thermoplastic for durability and resistance to soldering temperatures.
• Termination Style: Through-hole termination for secure mounting to the PCB.
• Stacking Height: Provides a specific distance between stacked boards, as determined by the "-811" designation.

Benefits:

• Space Saving: Compact design allows for high-density board stacking in limited spaces.
• Reliable Connection: Gold-plated contacts ensure a stable and corrosion-resistant electrical connection.
• Easy Assembly: Through-hole termination simplifies the soldering process.
• Design Flexibility: Available in various stacking heights to accommodate different application requirements.
• Durable Construction: High-temperature thermoplastic insulator ensures reliable performance in harsh environments.

Additional Details:

The DW-32-20-G-T-811 features a specific number of positions per row, indicated by the "-20" in the part number, meaning 20 contacts per row, for a total of 40 contacts. The "G" denotes gold plating. The "T" signifies through-hole termination. The "-811" likely refers to a specific stack height, however specific data sheets should be consulted to confirm. These connectors are designed for automated assembly processes and can withstand standard reflow soldering temperatures. They are often used in applications requiring robust and reliable inter-board connections. Samtec offers extensive technical documentation, including 2D/3D models and footprint recommendations, to facilitate design integration.
