Frequently Asked Questions
How does the 0.100-inch pitch of TSM-128-01-TL-DH-A-K-TR compare to 0.050-inch pitch connectors for signal routing density?
The TSM-128-01-TL-DH-A-K-TR uses a 0.100-inch (2.54 mm) pitch, which is twice the spacing of 0.050-inch (1.27 mm) pitch connectors. This larger pitch makes PCB layout and manual inspection easier and provides more mechanical robustness per contact, but results in a longer connector body for the same 56-position count, making it better suited for designs where board space allows standard pitch rather than ultra-dense layouts.
What does the tape-and-reel (TR) suffix indicate for TSM-128-01-TL-DH-A-K-TR, and why does it matter for high-volume production?
The TR suffix indicates the TSM-128-01-TL-DH-A-K-TR is packaged in tape-and-reel format, which feeds directly into automated pick-and-place machines used in high-volume SMT assembly. Tape-and-reel packaging eliminates manual component loading, reduces placement error on the 56-position single-row footprint, and enables continuous production runs with reel quantities typically ranging from 500 to 1000 pieces per reel.
Which mating socket connector should be used with TSM-128-01-TL-DH-A-K-TR to complete a board-stacking assembly?
The TSM-128-01-TL-DH-A-K-TR is designed to mate with SAMTEC SFM series socket strips sharing the 0.100-inch (2.54 mm) pitch and 56-position single-row layout. The DH (dual height) contact design accommodates different stack height configurations, giving designers options for inter-board clearance depending on the height of components mounted on the daughter card between the two boards.
Is TSM-128-01-TL-DH-A-K-TR appropriate for industrial designs requiring operation across a wide temperature range?
Yes. SAMTEC TSM series terminal strips are rated for operation over a temperature range typically spanning -55°C to +125°C, making the TSM-128-01-TL-DH-A-K-TR suitable for industrial control panels, factory automation I/O modules, and embedded computing boards that must function reliably in harsh thermal environments. The 56-position SMT format also meets standard industrial vibration and shock requirements when properly reflowed.
