What are the key features of TSM-126-01-FM-DH-A-K-TR?
- 52-position single-row .100" (2.54 mm) pitch terminal strip for broad signal routing in surface mount assemblies
- Dual-height (DH) body profile with kinked (K) solder tails provides mechanical stability and alignment during SMT reflow soldering
- Tape-and-reel (TR) packaging for automated pick-and-place assembly, reducing placement time in high-volume production runs
What is TSM-126-01-FM-DH-A-K-TR used for?
The TSM-126-01-FM-DH-A-K-TR is used in backplane interconnect designs, industrial controller cards, and test fixture boards where a 52-position single-row SMT terminal strip at 2.54 mm pitch is required. Its dual-height body suits applications needing elevated mating clearance above the PCB surface, such as through-board cable routing. The tape-and-reel packaging integrates smoothly into automated assembly lines for high-throughput electronics manufacturing.

Frequently Asked Questions
What does the DH suffix mean in TSM-126-01-FM-DH-A-K-TR and how does it affect mounting height?
The DH suffix stands for dual-height, indicating a taller body profile compared to the standard single-height TSM variant. The dual-height body raises the mating interface approximately 4 mm above the standard position, providing clearance for routing cables or PCB traces beneath the connector. This is especially useful in 52-position backplane and industrial control assemblies where component clearance above the board is critical.
For a 52-position SMT terminal strip, how does the TSM-126-01-FM-DH-A-K-TR perform in automated reflow soldering?
The TSM-126-01-FM-DH-A-K-TR uses kinked (K) solder tails that lock into PCB pads and prevent tombstoning during reflow at temperatures up to 260°C. Its tape-and-reel packaging ensures consistent pick-and-place positioning within ±0.05 mm, which is essential for maintaining coplanarity across all 52 solder joints in a single-pass reflow cycle on high-speed assembly lines.
When is TSM-126-01-FM-DH-A-K-TR a suitable choice compared to a through-hole terminal strip of the same pitch?
The TSM-126-01-FM-DH-A-K-TR is preferred over through-hole alternatives when a double-sided PCB design cannot accommodate via drills for 52 pins at 2.54 mm pitch or when wave soldering is not available. Its SMT footprint saves roughly 50% of the board-layer space consumed by plated through-holes and allows placement on either board side, supporting high-density backplane and control card designs in modern surface mount production environments.
