Key Features
- 56-position dual-row configuration at 2.54 mm pitch delivering dense signal connectivity in a compact SMT footprint
- Low-profile surface mount termination enabling reflow soldering compatibility and reduced PCB height clearance requirements
- Tape-and-reel (TR) packaging optimized for high-volume automated pick-and-place SMT production
Applications
The TSM-128-01-STL-DH-A-K-TR terminal strip is applied in embedded computing modules, test and measurement backplanes, and industrial control cards that require 56 signal lines through a standard 2.54 mm pitch SMT interface. Its dual-row layout reduces the board edge length needed for high-pin-count signal access compared to single-row alternatives.

Frequently Asked Questions
How many pins does the SAMTEC TSM-128-01-STL-DH-A-K-TR provide and in what arrangement?
The TSM-128-01-STL-DH-A-K-TR provides 56 pins in a dual-row arrangement at 2.54 mm (0.100") pitch, giving a 28 × 2 configuration that carries up to 56 independent signals on a standard grid compatible with common mating headers and test probes.
What current rating should designers assume per contact for the SAMTEC TSM-128 series terminal strip?
SAMTEC TSM series surface mount terminal strips are rated for approximately 3 A per contact at up to 250 V, so the TSM-128-01-STL-DH-A-K-TR can handle mixed power-and-signal backplane connections across standard 3.3 V, 5 V, and 12 V board-level power domains.
How does the TSM-128-01-STL-DH-A-K-TR differ from TSM-127-02-SM-DH-A-K-TR in pin count and board footprint?
The TSM-128-01-STL-DH-A-K-TR carries 56 pins versus 54 pins in the TSM-127-02, adding 2 more signal positions at the same 2.54 mm pitch; both use dual-row SMT layouts, but the 128 variant occupies a slightly longer PCB footprint to accommodate the additional 2-pin column.
