Frequently Asked Questions
What pin count and pitch does TSM-128-04-TL-DH-A-P-TR offer for dual-row interconnect designs?
TSM-128-04-TL-DH-A-P-TR provides 56 contact positions in 2 rows on a standard 0.100 inch (2.54 mm) pitch, giving engineers a high-density interconnect option for backplane, daughtercard, and module-to-baseboard designs on standard PCB manufacturing tolerances.
How do through-hole locating pegs (TL) on this SAMTEC terminal strip improve SMT soldering quality?
Through-hole locating pegs mechanically anchor the 56-pin connector body to the PCB before and during reflow soldering at temperatures up to 260°C, minimizing drift and ensuring all 56 contacts land within pad tolerances, which reduces rework rates on automated assembly lines.
When should a procurement engineer choose TSM-128-04-TL-DH-A-P-TR over a comparable tin-plated variant?
Gold-plated (-P) contacts are preferred over tin when the design requires more than 50 mating cycles, low and stable contact resistance below 20 mΩ, or operation in humid or mildly corrosive environments, making the gold-plated TSM-128-04-TL-DH-A-P-TR the correct choice for modular industrial or test-equipment applications.
What tape-and-reel specifications make TSM-128-04-TL-DH-A-P-TR suitable for high-volume automated assembly?
The -TR suffix indicates standard EIA-481 tape-and-reel packaging compatible with 24 mm or 32 mm carrier tape feeders on pick-and-place machines. Volume orders typically come in reels of 500 pieces, reducing per-unit setup overhead for production runs exceeding 1,000 boards.
