Key Features
- 50-position dual-row SMT layout on 0.100" (2.54 mm) pitch delivers high-density signal routing in a standard industry footprint
- Stainless steel (SS) hardware provides corrosion resistance and enhanced mechanical durability for demanding industrial and outdoor deployment environments
- Tape-and-reel (TR) packaging supports automated pick-and-place SMT assembly, enabling efficient high-volume production with minimal manual handling
Applications
The TSM-125-01-SS-DH-A-K-TR serves as a high pin-count board-to-board terminal strip in industrial control systems, rugged embedded computers, and test equipment requiring 50 signal connections at 0.100" pitch. Its stainless steel hardware makes it suitable for harsh environment applications exposed to moisture, chemicals, or vibration. The dual-row SMT configuration supports compact PCB layouts in data acquisition and communication modules.

Frequently Asked Questions
How many positions does TSM-125-01-SS-DH-A-K-TR provide, and what is its row configuration?
The TSM-125-01-SS-DH-A-K-TR provides 50 total positions in a dual-row arrangement at 0.100" (2.54 mm) pitch, with 25 positions per row. This configuration routes 50 individual signals across a board edge in a standard SMT footprint, supporting parallel bus interfaces, multi-channel sensor inputs, or mixed signal-and-power connections in industrial and embedded applications.
Why does the SS (stainless steel) hardware designation matter for harsh-environment deployments?
Stainless steel hardware in the TSM-125-01-SS-DH-A-K-TR resists corrosion from humidity, salt spray, and chemical exposure better than standard brass or zinc alloy alternatives. In outdoor industrial controllers or marine electronics exposed to moisture, the stainless steel retains mechanical integrity across temperature swings from -40°C to 85°C or beyond, preventing loosening of the 50-position connector under vibration over extended service life.
How does TSM-125-01-SS-DH-A-K-TR compare to a 0.050" pitch alternative for a 50-signal interface?
At 0.100" (2.54 mm) pitch, the TSM-125-01-SS-DH-A-K-TR occupies approximately twice the PCB edge length of a 0.050" pitch 50-position connector, but offers broader contact spacing that tolerates larger positional tolerances and simpler PCB routing. Designers choose 0.100" when impedance-controlled routing allows wider trace spacing, or when mating with standard 0.100" pitch headers already in the system. Cost per position is typically lower than fine-pitch alternatives.
