Key Features
- 74-position dual-row layout at 0.050" (1.27 mm) pitch provides very high contact density for large board-to-board signal buses in compact PCB footprints
- Right-angle (L) surface mount termination enables horizontal mating orientation, ideal for edge-access and panel-interface board designs
- Tape-and-reel (TR) packaging supports automated pick-and-place SMT reflow assembly for high-volume production runs
- Gold-plated stamped contacts deliver low contact resistance and reliable performance over extended mating cycles in industrial and embedded systems
Applications
The SFM-137-02-L-D-A-K-TR is suited for large-format board-to-board and edge-interface signal connections in FPGA module systems, high-channel-count data acquisition platforms, and industrial automation controllers requiring 74 signal positions at 0.050" pitch in a right-angle orientation. The right-angle termination style is especially useful when mating connectors must be accessed from the side of a PCB assembly, such as in card-cage or panel-mount configurations. Its tape-and-reel packaging makes it an efficient choice for production environments running automated SMT lines with tight placement tolerances.

Frequently Asked Questions
What does the right-angle (L) termination style of SFM-137-02-L-D-A-K-TR enable in PCB layout and system integration?
The L (right-angle) termination on SFM-137-02-L-D-A-K-TR orients the mating interface perpendicular to the PCB surface, allowing the 74-position dual-row socket at 0.050" (1.27 mm) pitch to connect to a mating connector from the board edge. This is ideal for card-cage assemblies, panel-mount applications, or stacked board configurations where vertical space is limited.
For a 74-position signal bus at 0.050" pitch, how does SFM-137-02-L-D-A-K-TR compare to using two smaller connectors?
A single SFM-137-02-L-D-A-K-TR provides 74 contacts (37 per row) at 0.050" (1.27 mm) pitch in one continuous housing, which eliminates the alignment complexity and potential signal discontinuity of using two separate 37-position connectors. It also reduces BOM entries and simplifies SMT placement in automated reflow production.
What industries require a 74-position 0.050" pitch right-angle socket like SFM-137-02-L-D-A-K-TR?
Industries including defense electronics, high-performance computing, FPGA prototyping, and industrial automation commonly require 74-position 0.050" (1.27 mm) pitch right-angle socket strips like the SFM-137-02-L-D-A-K-TR to interface high-channel-count I/O boards, backplane signal buses, and modular instrument cards where side-access mating at high pin counts is essential.
How does tape-and-reel packaging of SFM-137-02-L-D-A-K-TR benefit volume PCB assembly operations?
Tape-and-reel (TR) packaging of SFM-137-02-L-D-A-K-TR enables automated pick-and-place machines to handle 74-position right-angle SMT connectors at 0.050" (1.27 mm) pitch with precise orientation control, reducing manual handling errors and supporting continuous high-throughput SMT reflow assembly lines producing hundreds or thousands of units per shift.
