Frequently Asked Questions
How many contact positions does the TSM-120-03-LM-DH-A-K-TR provide and at what pitch?
The TSM-120-03-LM-DH-A-K-TR offers 40 total positions arranged in a dual-row layout at 0.100" (2.54 mm) pitch, with 20 contacts per row, making it suitable for high-density signal routing in embedded computing and industrial applications.
What does the keying option (K suffix) on the TSM-120-03-LM-DH-A-K-TR prevent during board assembly?
The K suffix indicates a keying feature that physically prevents incorrect mating with non-keyed or misaligned connectors. This reduces assembly errors on PCBs with multiple 40-position headers at 0.100" pitch, which is critical in high-mix manufacturing environments with similar-looking connectors on the same board.
Is the TSM-120-03-LM-DH-A-K-TR compatible with high-volume automated SMT assembly?
Yes. The TSM-120-03-LM-DH-A-K-TR is supplied in tape-and-reel (TR) packaging, which is fully compatible with automated pick-and-place machines. Its surface mount termination supports reflow soldering at standard SMT profiles, enabling consistent placement of 40 contacts at 0.100" pitch in high-volume PCB production runs.
