Frequently Asked Questions
How many signal positions does SEAM-30-03.5-L-04-2-A-K-TR provide and what pitch does it use for board stacking?
The SEAM-30-03.5-L-04-2-A-K-TR provides 120 positions arranged on a 0.050" (1.27 mm) pitch open-pin-field array, enabling board stacking with very high density. This pitch and position count suits designs requiring 120 high-speed signal channels between stacked PCBs in a compact footprint measuring 1.696 inches in body length.
What contact finish does SEAM-30-03.5-L-04-2-A-K-TR use and how does it affect mating reliability in high-cycle applications?
The mating contacts feature 10 microinch gold over 50 microinch nickel plating, providing excellent corrosion resistance and low contact resistance across thousands of mating cycles. This finish is appropriate for board stacking applications that require reliable electrical continuity and reduced insertion force over the product lifecycle.
In which high-speed communication systems is SEAM-30-03.5-L-04-2-A-K-TR typically specified over traditional 0.100" pitch alternatives?
SEAM-30-03.5-L-04-2-A-K-TR is specified in FPGA mezzanine cards, advanced radar systems, and multi-gigabit networking equipment where signal density requirements exceed what 2.54 mm pitch connectors can provide. The SEARAY open-pin-field platform supports data rates of 10 Gbps per channel or higher, enabling SerDes and DDR interfaces in space-limited backplane designs.
