What are the key features of SFM-128-02-H-D-A-P-TR?
- 56-position dual-row layout at 0.050" (1.27 mm) pitch supports 56 signal connections in a compact fine-pitch SMT footprint
- High-reliability H-series contacts provide consistent low-resistance mating across the rated insertion cycle life
- Polarization (P) option prevents incorrect mating orientation, protecting sensitive signal and power connections during assembly and field maintenance
- Tape-and-reel (TR) packaging enables automated SMT pick-and-place for high-volume production with 260°C Pb-free reflow compatibility
What is SFM-128-02-H-D-A-P-TR used for?
The SFM-128-02-H-D-A-P-TR is used in FPGA mezzanine cards, high-speed data acquisition daughter boards, and industrial embedded computing modules requiring 56 fine-pitch signals at 0.050" pitch. Its polarized socket design prevents mating errors in field-replaceable module systems, making it well-suited for rugged automation equipment and server expansion cards. The tape-and-reel format supports automated assembly in telecommunications and defense electronics manufacturing.

Frequently Asked Questions
What is the contact pitch and total position count of the SFM-128-02-H-D-A-P-TR?
The SFM-128-02-H-D-A-P-TR has 56 positions in a dual-row arrangement with a 0.050" (1.27 mm) contact pitch, giving 28 contacts per row. The total mated length is approximately 27 × 1.27 mm ≈ 34 mm, providing a dense 56-signal interface in a fine-pitch SMT footprint suitable for high-speed digital systems.
How does the polarization (P) option of the SFM-128-02-H-D-A-P-TR protect the system during mating?
The P (polarization) option adds a mechanical keying feature that physically prevents the mating header from being inserted in the wrong orientation. This protects the 56-position 0.050" pitch signal interface from reverse-polarity connection events, which is critical in field-replaceable daughter cards and hot-swap module designs where incorrect insertion could damage 3.3 V or 1.8 V logic signals.
For which FPGA or processor module interfaces is the SFM-128-02-H-D-A-P-TR a suitable mezzanine connector?
The SFM-128-02-H-D-A-P-TR is compatible with FPGA mezzanine card (FMC) expansion interfaces and custom module-to-carrier board designs that use 0.050" (1.27 mm) pitch dual-row socket headers for up to 56 differential or single-ended signal pairs. It pairs with SAMTEC TSM or TFM header series on the carrier board side, supporting data rates up to several Gbps depending on the mated connector and trace design.
