Key Features
- 52-position dual-row configuration at 0.100 inch (2.54 mm) pitch for high-density SMT signal interfaces
- Stainless steel (SS) contact material providing superior corrosion resistance in harsh environments
- Tape-and-reel (TR) packaging enabling high-volume automated pick-and-place PCB assembly
- Dual-header footprint minimizes board edge length compared to equivalent single-row 52-pin strips
Applications
The TSM-126-03-SS-DH-A-K-TR is designed for signal interface strips on industrial control panels, ruggedized computing modules, and military-grade PCBs where 52 positions and corrosion-resistant stainless steel contacts are required. Its 0.100 inch pitch maintains backward compatibility with 2.54 mm grid board designs while enabling surface-mount assembly. Tape-and-reel packaging supports high-volume production in defense, aerospace, and outdoor industrial equipment manufacturing.

Frequently Asked Questions
How many signal positions does TSM-126-03-SS-DH-A-K-TR provide and what is its contact material?
The TSM-126-03-SS-DH-A-K-TR offers 52 positions in a dual-row layout at 0.100 inch (2.54 mm) pitch, with stainless steel contacts that provide corrosion resistance for applications in humid or chemically challenging environments.
What manufacturing advantage does the tape-and-reel (TR) packaging of TSM-126-03-SS-DH-A-K-TR provide?
The TR suffix confirms tape-and-reel packaging, allowing TSM-126-03-SS-DH-A-K-TR to be fed directly into automated pick-and-place machines, reducing manual handling and supporting high-volume SMT assembly with standard reflow soldering profiles.
In which harsh-environment applications is TSM-126-03-SS-DH-A-K-TR preferred over standard brass-contact alternatives?
Defense electronics, outdoor industrial controllers, and marine navigation equipment that expose connectors to salt spray or condensation favor TSM-126-03-SS-DH-A-K-TR's stainless steel contacts over brass, as they resist oxidation at 52 mating positions across the 2.54 mm pitch interface.
How does the dual-row design of TSM-126-03-SS-DH-A-K-TR impact PCB layout compared to a single-row strip?
Placing 52 signals in a dual-row arrangement at 2.54 mm pitch reduces the connector's board edge footprint to 26 columns versus 52 for a single-row strip, allowing more compact PCB layouts without sacrificing signal count in space-constrained designs.
