Key Features
- 28-position dual-row 2×14 layout on standard 0.100" (2.54 mm) pitch for broad mating compatibility
- Stainless-steel (SS) hardware providing enhanced corrosion resistance and mechanical durability in harsh environments
- Surface-mount vertical orientation enabling reflow soldering without through-hole drilling on single or double-sided PCBs
- Tape-and-reel packaging for seamless integration with automated pick-and-place assembly lines
Applications
The TSM-128-05-SS-SH-P-TR is used in industrial control panels, test and measurement chassis, and embedded system backplanes where a 28-contact 0.100" dual-row header with corrosion-resistant hardware is required. Its surface-mount vertical profile suits dense PCB assemblies in telecommunications equipment and instrumentation racks. The stainless-steel hardware option makes it particularly suitable for outdoor equipment enclosures or humid industrial environments where standard tin-plated hardware would corrode.

Frequently Asked Questions
How many contacts does the TSM-128-05-SS-SH-P-TR carry, and what row configuration is used?
The TSM-128-05-SS-SH-P-TR has 28 contacts in a 2×14 dual-row arrangement on a 0.100" (2.54 mm) pitch. This standard pitch mates with a wide range of off-the-shelf 0.100" female connectors and ribbon-cable IDC sockets, making it a versatile choice for board-to-board and cable-to-board interconnect in industrial and embedded applications.
Why does the TSM-128-05-SS-SH-P-TR include stainless-steel hardware, and where is this feature most valuable?
The SS (stainless-steel) hardware designation means the mounting and retention hardware is manufactured from stainless steel rather than standard carbon steel, offering better resistance to oxidation and corrosion in environments with humidity above 85% RH or exposure to industrial chemicals. This feature is most valuable in outdoor weatherproof enclosures, marine electronics, food-processing equipment, and HVAC control boards where long-term corrosion resistance is required to maintain contact integrity over a 10-year or longer product lifetime.
Does the surface-mount design of the TSM-128-05-SS-SH-P-TR support standard lead-free reflow soldering?
Yes. The TSM-128-05-SS-SH-P-TR is a surface-mount component compatible with standard lead-free reflow profiles at 260 °C peak solder temperature. The tape-and-reel (TR) format positions each part precisely in the carrier tape for automated pick-and-place equipment, eliminating the manual insertion step needed for through-hole alternatives and reducing per-unit assembly labor by roughly 30 seconds per connector in typical SMT line configurations.
When would an engineer select the TSM-128-05-SS-SH-P-TR over a 0.050" pitch connector for a backplane interface?
An engineer chooses the 0.100" pitch TSM-128-05-SS-SH-P-TR when signal density does not require 0.050" spacing and when lower-cost, widely available 0.100" mating receptacles or IDC ribbon connectors must be used. The 0.100" pitch also relaxes PCB trace-width and spacing design rules compared to 0.050" pitch, enabling use of standard 6-mil design rules on cost-effective 2-layer boards. For 28 signals, this connector fits in about 38 mm of connector length while remaining compatible with a broader range of off-the-shelf mating hardware.
