Key Features
- 52-position dual-row SMD socket at 0.050" (1.27 mm) pitch with 104 total contacts for high-density board-to-board stacking
- High-reliability contact retention system delivers stable mating force and low contact resistance across extended use cycles
- Tape-and-reel (-TR) packaging enables automated SMT pick-and-place placement at production volumes
- Surface-mount design compatible with standard reflow soldering profiles, eliminating the need for through-hole drilling
Applications
The SFM-126-L2-H-D-A-K-TR is used in dual-board stacking architectures for embedded computing modules, industrial I/O expansion cards, and signal acquisition systems requiring 52-position dual-row interconnect at 0.050" pitch. Its 104-contact configuration supports parallel bus interfaces, high-speed differential pairs, and power distribution between adjacent boards. The tape-and-reel format streamlines high-volume SMT assembly on automated production lines.

Frequently Asked Questions
What is the total pin count and row configuration of the SFM-126-L2-H-D-A-K-TR?
The SFM-126-L2-H-D-A-K-TR features 104 total contacts arranged in 52 positions per row across a dual-row 0.050" (1.27 mm) pitch layout, providing a high-density mating interface for board-to-board stacking applications.
For an industrial I/O expansion design, how does the 52-position dual-row layout of the SFM-126-L2-H-D-A-K-TR benefit the PCB routing?
The dual-row 0.050" pitch configuration concentrates 104 signal contacts within approximately 66 mm of board length, allowing routing of up to 52 differential pairs or a wide parallel bus across the board-to-board interface without excessive PCB area.
Does tape-and-reel packaging affect the minimum order quantity for the SFM-126-L2-H-D-A-K-TR?
Tape-and-reel packaging typically sets the minimum order at 1 reel, commonly containing 500 to 1000 pieces, which may be higher than tray packaging minimums but reduces per-unit cost significantly in medium to high production volumes.
When would a designer choose the 52-position SFM-126-L2-H-D-A-K-TR over the 46-position SFM-123 variant?
When a design requires more than 92 signal connections between boards, the SFM-126-L2-H-D-A-K-TR provides 104 contacts — 12 additional contacts over the SFM-123 — at the same 0.050" pitch, accommodating wider buses or additional power and ground pins without switching to a larger connector family.
