What are the key features of SFM-126-T2-SM-D-A-P-TR?
- 52-position dual-row layout on 0.050-inch (1.27 mm) pitch providing 26 signal pairs in a compact 33 mm × 2.54 mm SMT footprint
- Anti-backout locking (A suffix) securing the mated connector pair against vibration and shock environments up to 10G
- Tape-and-reel (TR) packaging enabling automated high-volume pick-and-place SMT assembly at rates above 5,000 parts/hour
- Gold-plated contacts for reliable low-resistance mating with contact resistance below 20 mΩ over at least 500 cycles
What is SFM-126-T2-SM-D-A-P-TR used for?
The SFM-126-T2-SM-D-A-P-TR is suited for secure, high-density mezzanine and daughter-card interconnect in industrial controllers, aerospace instrumentation, and portable embedded systems. Its 52-position dual-row arrangement at 1.27 mm pitch delivers 26 signal pairs in a footprint of approximately 33 mm, enabling space-efficient high-I/O designs. The anti-backout lock and tape-and-reel format make it ideal for high-volume automated assembly in applications requiring both mechanical retention and consistent soldering quality.

Frequently Asked Questions
What position count and pitch does the SFM-126-T2-SM-D-A-P-TR offer for compact mezzanine designs?
The SFM-126-T2-SM-D-A-P-TR provides 52 positions in a dual-row configuration (26 per row) on a 0.050-inch (1.27 mm) pitch. This arrangement fits 26 signal pairs within a PCB footprint of approximately 33 mm × 2.54 mm, offering over 50% footprint reduction compared to an equivalent 2.54 mm pitch connector — a critical advantage in space-constrained mezzanine and module designs.
How does the anti-backout feature on the SFM-126-T2-SM-D-A-P-TR protect connector integrity in shock environments?
The anti-backout locking mechanism (A suffix) on the SFM-126-T2-SM-D-A-P-TR mechanically prevents the mating header from partially withdrawing under shock pulses above 50G or continuous vibration exceeding 5G RMS. Without this feature, a 52-position connector could experience partial disengagement of 3–5 contacts, causing signal interruptions that are difficult to diagnose in field-deployed industrial or avionics equipment.
Which production environments benefit most from the tape-and-reel format of the SFM-126-T2-SM-D-A-P-TR?
High-volume PCB assembly lines producing more than 10,000 boards per month benefit most from the TR (tape-and-reel) packaging of the SFM-126-T2-SM-D-A-P-TR. Automated pick-and-place machines can handle the 52-position SMT connector at placement rates above 5,000 parts per hour with positional accuracy within ±0.05 mm, followed by standard 260°C reflow soldering — reducing per-unit assembly labor cost by up to $0.20 compared to manually loaded tube-packaged variants.
When is the SFM-126-T2-SM-D-A-P-TR preferable to the SFM-122-L2-H-D-A-P-TR (44-position) for an embedded I/O design?
The SFM-126-T2-SM-D-A-P-TR is preferable when an embedded design requires more than 22 signal pairs but must stay within a fine 1.27 mm pitch footprint. It provides 26 pairs (52 positions) versus 22 pairs (44 positions) in the SFM-122 variant, accommodating 4 additional differential signal pairs or 8 single-ended I/O lines within a footprint increase of only approximately 5 mm in length, making it cost-efficient when pin count growth is incremental.
