Key Features
- 52-position dual-row configuration at 0.050-inch pitch delivers 26 contacts per row for high pin-count board-to-board connections
- Short-profile (S) contact design reduces overall mated stack height for slim multi-board assemblies
- High-reliability rated socket for demanding applications requiring repeated mating and vibration resistance
- Tape-and-reel (TR) packaging ensures compatibility with automated pick-and-place SMT production lines
Applications
The SFM-126-T2-S-D-A-K-TR is ideal for high-density mezzanine and daughter-card interconnects in telecom backplanes, embedded computing systems, and industrial automation equipment where 52 signals or mixed power-signal channels must be routed between boards. Its 0.050-inch pitch short-profile socket minimizes the z-axis stack height while supporting reliable high-cycle mating. The SMT footprint enables seamless integration into modern lead-free reflow assembly processes.

Frequently Asked Questions
How many contacts are in the SFM-126-T2-S-D-A-K-TR and what is their arrangement?
The SFM-126-T2-S-D-A-K-TR has 52 total contacts arranged in a dual-row layout at 0.050-inch (1.27 mm) pitch, with 26 pins per row. This high-density arrangement supports simultaneous routing of 52 signal or power lines between two boards in mezzanine, backplane, or module stacking applications within a compact surface-mount footprint.
What does the short-profile (S) feature mean for PCB stack height in SFM-126-T2-S-D-A-K-TR?
The S designation indicates a short-profile contact, which reduces the connector's contribution to overall mated assembly height compared to standard or high-profile variants. In practice this allows a mated board pair to achieve a smaller separation, enabling slimmer enclosures in embedded computing modules, portable test instruments, and compact industrial controllers that have tight z-axis constraints.
What is the SFM-126-T2-S-D-A-K-TR's pitch, and why does 1.27 mm pitch matter for signal integrity?
The 0.050-inch (1.27 mm) pitch of the SFM-126-T2-S-D-A-K-TR keeps adjacent contacts close enough for high pin-count routing while maintaining adequate electrical isolation between pins. At this pitch, impedance-controlled differential pairs can be routed through the 52-pin connector at data rates up to several Gbps, meeting the needs of high-speed SerDes, LVDS, or similar interfaces used in telecom and data acquisition systems.
How should engineers specify a mating header for SFM-126-T2-S-D-A-K-TR?
Engineers should select a SAMTEC SFM series plug header with 52 positions, dual row, and matching 0.050-inch (1.27 mm) pitch to mate with the SFM-126-T2-S-D-A-K-TR. The resulting stacked assembly accommodates board-to-board separations typically ranging from 8 mm to 20 mm depending on the chosen header stack height, giving flexibility for power plane and signal routing between layers in multi-board system designs.
