What are the key features of TSM-128-04-SS-SH-A?
- 28-position dual-row layout at 2.54 mm (0.100 inch) pitch delivers high-density interconnection in a compact surface-mount footprint
- Stainless-steel contacts provide corrosion resistance and long-term reliability in harsh industrial and instrumentation environments
- Horizontal single-row orientation simplifies board edge or header mating in space-constrained PCB layouts
- Surface-mount termination enables automated pick-and-place assembly and reflow soldering for high-volume production
What is TSM-128-04-SS-SH-A used for?
The TSM-128-04-SS-SH-A is used in industrial control boards, embedded computing modules, and test-and-measurement instrumentation where a 28-pin dual-row 0.100 inch pitch header provides reliable board-to-board or wire-to-board connectivity. Its surface-mount design and horizontal orientation suit panel-mount PCBs and daughter-card architectures that require a low-profile, high-density connector with stainless-steel durability.

Frequently Asked Questions
How many pins does the TSM-128-04-SS-SH-A have, and how are they arranged on the connector body?
The TSM-128-04-SS-SH-A features 28 positions arranged in a dual-row configuration with a 2.54 mm (0.100 inch) pitch between adjacent pins. The dual-row layout concentrates connectivity into a narrow PCB footprint, accommodating 14 pins per row and making it suitable for high-density board-to-board or wire-to-board applications in industrial and instrumentation systems where connector real estate is limited.
What design advantage does the stainless-steel contact material of the TSM-128-04-SS-SH-A offer compared to standard brass contacts?
Stainless-steel contacts in the TSM-128-04-SS-SH-A provide superior corrosion resistance and mechanical strength compared to standard brass or phosphor-bronze contacts, which is critical in environments exposed to humidity, mild chemicals, or repetitive mating cycles exceeding hundreds of insertions. This material choice extends the connector's service life in industrial control panels, outdoor instrumentation enclosures, and test fixtures that demand long-term contact reliability.
Can the TSM-128-04-SS-SH-A be processed through standard SMT reflow soldering, and what pitch governs pad layout on the PCB footprint?
Yes, the TSM-128-04-SS-SH-A is a surface-mount component compatible with standard SMT pick-and-place and reflow soldering processes at typical lead-free reflow temperatures around 260°C. The 2.54 mm (0.100 inch) pitch governs the pad layout, which is one of the most widely supported footprints in PCB design libraries, simplifying integration into existing board designs and making the connector interchangeable with other 0.100 inch pitch dual-row SMT headers from SAMTEC or compatible manufacturers.
In which embedded computing or industrial control applications does the TSM-128-04-SS-SH-A's horizontal single-row orientation provide a layout benefit?
The horizontal single-row orientation of the TSM-128-04-SS-SH-A is particularly valuable in panel-mount PCBs, daughter-card assemblies, and rack-mount industrial controllers where mating connectors approach from the board edge or a parallel daughter board rather than perpendicular to the PCB surface. This orientation reduces overall assembly height and allows the 28-pin connector to mate with ribbon cable IDC connectors or edge-mounted headers in embedded computing backplanes and industrial I/O expansion cards.
