SAMTEC Samtec SEAM-40-02.0-S-10-2-AK-TR 400-way PCB header, 1.27mm

Specification
*Series: SEAM*Pitch: 1.27mm*Number of Positions: 400*Connection Orientation: Straight*Shrouded/Unshrouded: Shrouded*Connector System: Board-to-Board*Termination Method: Solder*Surface Finish: Contact: Gold*1.27 mm SEARAYTM Series Interconnects. SEARAYTM is a 1.27 mm high-density/high-speed board-to-board interconnect system. The SEAM/SEAF series connectors can be mapped for single-ended or differential pair applications. When routed as a single-ended system, the SEARAYTM is rated to 12.5 GHz @ -3 dB. The SEAM/SEAF series high-speed/high-density open pin-field arrays utilize Solder Charge Technology for exceptional solder joint reliability. The SEAM/SEAF series SEARAYTM high-speed/high-density open pin-field arrays utilize Samtec's edge-rate contact system for high-speed performance, zippered mating, and extremely low insertion and extraction forces. High density connectors with various row counts, ideal for board stacking applications. Stack heights from 7mm with SEAF/SEAM combinations. Contact resistance: 5.5 mΩ. Contact plating: 0.76 μm gold on contacts, matte tin on tails.
