Key Features
- 52-position dual-row configuration provides high pin count at 2.54 mm pitch in a compact SMT footprint
- Flat (F) contact style optimizes coplanarity for consistent solder joint formation across all 52 positions
- Anti-wicking (A) contact treatment prevents solder flow into the connector housing during reflow, maintaining contact integrity
- Dual-height (DH) housing option accommodates varying board-to-board stack heights in multi-board assemblies
- Tape-and-reel (TR) packaging enables high-volume automated pick-and-place SMT assembly
Applications
The TSM-126-02-F-DH-A-K-TR suits embedded computing modules, FPGA daughter cards, and industrial I/O backplanes where a 52-circuit dual-row SMT connector at 2.54 mm pitch is needed for board-to-board signal interconnection. Its anti-wicking and flat-contact design make it reliable in high-volume production environments running standard SMT reflow profiles up to 260°C. The dual-height housing option provides additional flexibility for mezzanine card designs that require varying standoff heights between the main board and the attached module.

Frequently Asked Questions
How many positions and rows does TSM-126-02-F-DH-A-K-TR have and what pitch separates each contact?
The TSM-126-02-F-DH-A-K-TR is a 52-position, dual-row surface mount terminal strip with contacts on a 2.54 mm (0.100") center-to-center pitch. The dual-row layout places 26 contacts per row, providing a total of 52 signal or power circuits in a connector body approximately 33 mm long, suitable for dense board-to-board signal routing in embedded systems.
What does the anti-wicking (A) contact treatment in TSM-126-02-F-DH-A-K-TR prevent during SMT reflow?
The anti-wicking treatment on TSM-126-02-F-DH-A-K-TR contacts prevents molten solder from flowing up the contact tails into the connector housing during reflow soldering at temperatures up to 260°C. Without this treatment, solder wicking can bridge contacts inside the housing, causing shorts across the 52 positions and requiring expensive rework. The anti-wicking feature is particularly important for high-pin-count SMT connectors assembled in high-volume production runs.
For a mezzanine card design requiring adjustable board-to-board standoff height, how does TSM-126-02-F-DH-A-K-TR's DH option help?
The DH (dual-height) housing option on TSM-126-02-F-DH-A-K-TR provides a taller insulator body compared to the standard single-height TSM series, accommodating board-to-board stack heights where additional clearance of several millimeters is required between the base PCB and the mezzanine module. This suits designs where components taller than 2 mm on the base board must fit beneath the mezzanine card without mechanical interference.
Is TSM-126-02-F-DH-A-K-TR supplied in tape-and-reel for automated assembly, and what production volume does this serve?
Yes, the -TR suffix confirms tape-and-reel packaging, typically with 500 or 1000 pieces per reel for use in automated SMT pick-and-place assembly. This packaging format ensures the 52-position connector is accurately fed to the placement head within ±0.1 mm, enabling high-yield solder joint formation across all 52 pads during standard IPC-compliant reflow profiles.
