Key Features
- 52-position dual-row layout on 0.100" (2.54 mm) pitch providing broad compatibility with standard PCB grid designs
- Gold-plated contacts rated at 3 A per pin enabling mixed signal and power distribution within a single connector
- Tape-and-reel (TR) packaging supporting automated SMT pick-and-place assembly for high-volume production
- Operating temperature range of -55°C to +125°C qualifying the part for industrial and military-grade applications
Applications
The TSM-126-04-SS-DH-A-K-TR is suited for high-density signal and power distribution headers in industrial automation, embedded computing, and test equipment where a 52-position 0.100" pitch SMT terminal strip is required. Its dual-row configuration provides 52 independent connections in a compact footprint, making it an efficient solution for backplane I/O and daughtercard-to-motherboard interfaces. The tape-and-reel format enables seamless integration into automated SMT assembly lines for consistent high-volume production.

Frequently Asked Questions
How many positions and rows does the TSM-126-04-SS-DH-A-K-TR contain, and what is the per-pin current rating?
The TSM-126-04-SS-DH-A-K-TR has 52 positions arranged in 2 rows of 26, on a 0.100" (2.54 mm) pitch. Each contact is rated at 3 A, giving a total potential current capacity of 156 A across all 52 pins. Designers typically derate to 70% under continuous load, especially above 85°C, to maintain reliable connector performance.
Which reel and packaging format does TSM-126-04-SS-DH-A-K-TR use, and what does that mean for assembly line setup?
The -TR suffix on the TSM-126-04-SS-DH-A-K-TR denotes tape-and-reel packaging, which is compatible with standard SMT pick-and-place machines accepting EIA-481 carrier tape. This format eliminates manual placement for the 52-position terminal strip, reducing placement cycle time and improving placement accuracy to within ±0.05 mm on automated assembly lines processing high-volume PCB runs.
When should a designer choose the TSM-126-04-SS-DH-A-K-TR over a through-hole header for a 52-position interface?
The SMT TSM-126-04-SS-DH-A-K-TR is preferred when PCB thickness is limited to under 1.6 mm, when board-to-board height must stay below 5 mm, or when all components are being reflowed in a single SMT pass. Through-hole alternatives offer higher pull-out retention—typically exceeding 20 N per pin—whereas the SMT variant relies on solder joint strength, which is sufficient for most static-mount applications below 5 g vibration.
Is the TSM-126-04-SS-DH-A-K-TR compatible with standard 0.100" pitch headers from other manufacturers?
The TSM-126-04-SS-DH-A-K-TR is designed to mate with SAMTEC's TSM and TSW series male headers on the standard 0.100" (2.54 mm) dual-row pitch, which is the same grid used by many industry-standard connectors. While mechanical compatibility exists with many 2.54 mm pitch headers from other manufacturers, Samtec recommends mating only with qualified header partners to ensure the gold contact finish retains its rated 3 A per pin performance over the specified mating cycle life.
