What are the key features of TSM-124-02-SS-DH-A-K-TR?
- 48-position dual-row 0.100" (2.54 mm) pitch layout delivers high contact density compatible with standard 0.1" grid PCB designs
- Stainless steel (SS) tail variant provides enhanced corrosion resistance and mechanical durability in harsh-environment board connections
- Tape-and-reel (TR) delivery enables automated pick-and-place SMT assembly, reducing handling time in high-volume production
What is TSM-124-02-SS-DH-A-K-TR used for?
TSM-124-02-SS-DH-A-K-TR is used in backplane connections, FPGA development board expansion headers, and industrial control PCBs requiring high pin-count surface-mount terminal strips at standard 0.100" pitch. Its 48-position dual-row format supports dense I/O routing for signal and power distribution across processor boards, sensor interface modules, and embedded computing platforms where reliable SMT attachment is essential.

Frequently Asked Questions
How many positions does the TSM-124-02-SS-DH-A-K-TR have and what pitch does it use?
The TSM-124-02-SS-DH-A-K-TR provides 48 total positions arranged in a dual-row configuration with a 0.100" (2.54 mm) pitch per row. This standard pitch ensures compatibility with conventional 0.1" grid PCB layouts and matching male header pins widely used in development boards, test fixtures, and embedded module connector systems.
What does the stainless steel tail designation mean for this SAMTEC TSM series connector?
The SS designation indicates stainless steel press-fit or surface-mount tails, which offer superior corrosion resistance compared to standard brass or phosphor bronze tails. This makes the TSM-124-02-SS-DH-A-K-TR suitable for marine, outdoor industrial, and high-humidity environments where moisture or contaminants could degrade standard copper alloy contacts over the connector's operational lifetime of 30 or more mating cycles.
For a 48-pin bus expansion header on an FPGA board, what board area does this connector occupy?
With 0.100" (2.54 mm) dual-row pitch and 24 positions per row, the TSM-124-02-SS-DH-A-K-TR spans approximately 60.96 mm (24 × 2.54 mm) along its length and 2.54 mm between the two rows. This footprint fits directly into standard 2×24 dual-row SMT pad layouts used on 1.6 mm FR4 PCBs, occupying roughly 60 mm × 5 mm of board space including pad keep-out areas.
Does TSM-124-02-SS-DH-A-K-TR support reflow soldering and what packaging format is available?
Yes, TSM-124-02-SS-DH-A-K-TR is packaged in tape-and-reel (TR) format for automated SMT pick-and-place assembly and is compatible with standard lead-free reflow soldering profiles peaking at 260°C. The surface-mount termination style eliminates wave-solder requirements, and the SAMTEC TSM series is rated for operating temperatures from -55°C to +125°C across industrial and commercial applications.
