What are the key features of TFM-126-01-STL-D-A-P-TR?
- 52-position dual-row SMT terminal strip at 0.050" (1.27 mm) pitch for high-density mezzanine interconnects
- Tiger Eye multi-finger contact delivers high normal force and stable contact resistance below 20 milliohms across 500+ mating cycles
- Tape-and-reel (TR) packaging enables automated pick-and-place assembly on high-volume SMT production lines
What is TFM-126-01-STL-D-A-P-TR used for?
The TFM-126-01-STL-D-A-P-TR is suited for high-density board-to-board mezzanine connections in embedded computing, avionics, and instrumentation hardware requiring 52 signal lines at 1.27 mm pitch. The polarized (P) configuration prevents incorrect mating in assemblies where connector orientation is critical, and the solderable tail construction ensures robust SMT joints in reflow-soldered platforms. Tape-and-reel packaging supports high-throughput automated assembly lines.

Frequently Asked Questions
How does the solderable tail (STL) variant of TFM-126-01-STL-D-A-P-TR differ from a standard press-fit termination?
The STL (solderable tail) termination uses a shaped lead that flows solder during reflow at 260°C peak temperature, creating a robust metallurgical bond compared to press-fit contacts that rely on mechanical interference in 1.0 mm to 1.6 mm plated-through holes. This makes the STL variant preferred for high-volume SMT manufacturing lines where automated reflow soldering produces consistent, inspectable solder joints across all 52 positions.
Which design scenarios require the polarized (P) option on this 52-position dual-row connector?
The polarized option physically prevents reverse mating by including a keying feature on the 52-position, 0.050" pitch dual-row housing, which is critical in assemblies where mating a connector backwards would apply voltage or signals to wrong pins and potentially damage components. This option is specified for avionics daughtercards, medical instrument modules, and military embedded computing boards operating at voltages up to 125 V AC where mis-mating carries safety or reliability consequences.
What tape-and-reel reel diameter and packaging format does TFM-126-01-STL-D-A-P-TR ship in for automated assembly procurement?
The TFM-126-01-STL-D-A-P-TR ships in standard 13" (330 mm) diameter tape-and-reel format on 8 mm or 12 mm embossed carrier tape, depending on the connector outline, enabling direct loading into automated pick-and-place machines without hand-kitting. This packaging format supports continuous production runs of thousands of units per reel, reducing changeover time on SMT lines assembling 52-position mezzanine boards in high-volume manufacturing.
