Key Features
- 66-position dual-row SMT socket at 0.050 inch (1.27 mm) pitch for very high density board-to-board signal interconnects
- Straddle-mount tail style (STL) allows the connector to straddle the PCB edge for unique board-edge mating configurations
- Kinked (K) tail option mechanically holds the 66-pin socket in place on SMT pads during automated reflow soldering
Applications
The SFM-133-T2-STL-D-A-K is designed for high-density board-edge and board-to-board SMT interconnects in FPGA daughter modules, high-speed data acquisition cards, and embedded computing systems. Its 66-pin dual-row straddle-mount configuration allows mating along the PCB edge, enabling compact system designs where connectors must be placed at board boundaries. The kinked tail ensures accurate component placement and solder joint integrity during high-volume SMT production runs.

Frequently Asked Questions
What does the straddle-mount tail style (STL) mean for the SFM-133-T2-STL-D-A-K?
The straddle-mount tail style means the 66-pin socket connector's termination tails straddle the PCB edge rather than mounting entirely on one surface, enabling the connector to mate with a mating header inserted from the board's side or edge, saving vertical board space in tight 0.050 inch pitch SMT assemblies.
How many signal contacts does the SFM-133-T2-STL-D-A-K provide and at what pitch?
The SFM-133-T2-STL-D-A-K offers 66 total contacts in a dual-row arrangement of 33 positions per row at 0.050 inch (1.27 mm) pitch, making it one of the higher contact-count options in the SAMTEC SFM series for dense signal routing in board stacking applications.
Which module-to-board designs can take advantage of the SFM-133-T2-STL-D-A-K's 66-pin layout?
FPGA mezzanine cards, processor daughtercards, and high-speed I/O expansion boards that require 66 signal channels at 1.27 mm pitch benefit from this connector, especially when the board-edge straddle mount reduces the PCB footprint compared to fully surface-mounted 66-pin alternatives.
What mating header series is compatible with the SFM-133-T2-STL-D-A-K?
The SFM-133-T2-STL-D-A-K mates with SAMTEC TSM or TFM series male header strips with 66-pin dual-row configuration at 0.050 inch (1.27 mm) pitch, achieving stacking heights that typically range from 0.1 inch to several millimeters depending on the selected mating pair's tail length.
