Frequently Asked Questions
How many positions does the TSM-135-02-SS-DH-A-K-TR provide, and what row configuration does it use?
The TSM-135-02-SS-DH-A-K-TR provides 70 positions total arranged in a dual-row (DH) configuration with 35 positions per row on a 0.100 inch pitch, enabling very high pin count SMT board interconnect in a standard footprint.
What is the benefit of the keyed (K) option on the TSM-135-02-SS-DH-A-K-TR for system assembly?
The K keying option physically prevents incorrect mating orientation on the 70-position dual-row connector, reducing assembly errors in systems with multiple 0.100 inch pitch headers and avoiding costly field failures from misconnected boards.
Which high pin count PCB designs are best matched to this 70-position SAMTEC terminal strip?
FPGA daughter cards, server backplanes, industrial controllers, and communications line cards that require 70 or more signals on a 0.100 inch pitch standard grid are ideal candidates for this dual-row SMT terminal strip.
Does tape-and-reel packaging affect minimum order quantities for the TSM-135-02-SS-DH-A-K-TR?
Tape-and-reel (TR) variants like TSM-135-02-SS-DH-A-K-TR are optimized for automated pick-and-place and are typically packaged in reels of hundreds of units, so buyers planning low-quantity prototype builds should verify minimum reel quantity, which is often 500 or 1000 pieces.
