Frequently Asked Questions
How many positions does the SEAM-50-02.0-S-10-2-A-K-TR support and what is its stacking height?
The SEAM-50-02.0-S-10-2-A-K-TR provides 500 positions in a high-density array configuration with a 2.0 mm board-to-board stacking height. This combination delivers extremely high signal density per unit area, making it suitable for compact server blades, FPGA mezzanine cards, and telecom line cards where space is at a premium.
What contact plating does the SEAM-50-02.0-S-10-2-A-K-TR use and how does it affect reliability?
The connector uses gold-plated contacts, which provide a contact resistance typically below 20 milliohms and excellent corrosion resistance over thousands of mating cycles. Gold plating is critical for high-cycle laboratory and field-serviceable equipment where connector oxidation would degrade signal integrity on 500-position high-speed differential pairs.
What does the polarization post on the SEAM-50-02.0-S-10-2-A-K-TR prevent during board assembly?
The polarization post acts as a physical keying feature that prevents the connector from being mated in the wrong orientation, a critical safeguard on a 500-pin assembly where a mis-inserted board would apply voltage to incorrect pins and risk damaging FPGAs or ASICs costing hundreds of dollars. The post also aids PCB alignment during automated SMT placement and hand assembly.
Which Samtec connector families mate with the SEAM-50-02.0-S-10-2-A-K-TR?
The SEAM series mates with Samtec's SEAF and SEAHF receptacle families in the SEARRAY and SAMARRAY system, supporting signal pitches of approximately 1.27 mm per row. The system accommodates stack heights from 2.0 mm up to 10 mm or more, allowing designers to select the stacking dimension that best fits their PCB-to-PCB spacing requirement in backplane or mezzanine configurations.
Why choose tape-and-reel (-TR) packaging for the SEAM-50-02.0-S-10-2-A-K-TR in a production environment?
The -TR suffix indicates the connector is supplied on tape-and-reel for automated SMT pick-and-place equipment, enabling placement rates of several hundred components per hour with consistent position accuracy below 0.1 mm. For a large 500-pin connector at 2.696" body length, automated placement eliminates the manual alignment errors and handling damage common with bulk-tray or tube-fed components in volume production.
