Frequently Asked Questions
How many total signal positions does the TSM-128-03-TL-DH-P-TR support in its dual-row layout?
The TSM-128-03-TL-DH-P-TR provides 56 positions total in a dual-row (DH) configuration, offering 28 contacts per row at a 0.100 inch (2.54 mm) pitch. This high-pin-count layout is well-suited for complex signal buses, industrial I/O expansion boards, and communication backplanes that require many parallel connections in a single connector footprint.
What SMT assembly process is compatible with the TSM-128-03-TL-DH-P-TR, and does its packaging support automated production?
The TSM-128-03-TL-DH-P-TR is designed for surface mount reflow soldering and comes in tape-and-reel (TR) packaging, which supports automated pick-and-place assembly on standard SMT production lines. The 0.100 inch pitch and 56-position footprint provide consistent alignment during placement, making it suitable for high-volume manufacturing of industrial and computing PCB assemblies.
For a PLC expansion module design, why choose TSM-128-03-TL-DH-P-TR over a 0.050 inch pitch connector?
The 0.100 inch (2.54 mm) pitch of TSM-128-03-TL-DH-P-TR offers greater mechanical robustness and easier hand-soldering or rework compared to 0.050 inch pitch alternatives. The wider pitch also accommodates higher current-carrying capacity per contact and is more tolerant of PCB registration tolerances, which benefits high-reliability industrial PLC and motor control applications where ruggedness is prioritized over extreme miniaturization.
Is TSM-128-03-TL-DH-P-TR a suitable choice for signal distribution in multi-board computing systems?
Yes, the 56-position dual-row configuration at 0.100 inch pitch provides enough contacts for parallel bus architectures, GPIO expansion, and mixed signal-and-power distribution in multi-board computing systems. The surface mount form factor and tape-and-reel packaging enable efficient volume production, and the 2.54 mm pitch is compatible with a broad ecosystem of mating socket connectors from SAMTEC and other manufacturers.
