Key Features
- 34-position dual-row layout at 1.27 mm (0.050") pitch supporting up to 34 signal or power connections per connector
- Low-profile metal shield (LM) option reducing overall stack height while providing EMI protection
- Polarization peg (P option) prevents mis-mating and ensures correct orientation during assembly
- Surface-mount construction with through-hole assist pegs (A option) for superior board retention and mechanical stability
Applications
The SFM-117-T2-LM-D-A-P is optimized for dense mezzanine and daughter-card applications in embedded computing, FPGA development boards, and industrial control systems requiring 34 dual-row connections at 1.27 mm pitch. Its low-profile metal shield minimizes EMI in high-speed digital environments, while the polarization peg prevents assembly errors during high-volume production. The connector is well-suited for military, medical, and telecommunications platforms demanding mechanical robustness and signal integrity.

Frequently Asked Questions
What is the position count and pitch of the SFM-117-T2-LM-D-A-P connector?
The SFM-117-T2-LM-D-A-P provides 34 positions in a dual-row configuration with a 1.27 mm (0.050 inch) pitch. This arrangement delivers up to 34 signal or power lines per connector pair, making it suitable for data-intensive board-to-board interfaces in embedded and FPGA-based systems.
How does the low-profile metal shield (LM) option on the SFM-117-T2-LM-D-A-P reduce stack height without compromising EMI shielding?
The low-profile metal shield (LM) option trims the vertical profile compared to a full metal shield, lowering the mated stack height by approximately 0.5 mm to 1 mm while still attenuating radiated EMI at frequencies above 1 GHz. This balance of shielding and compact geometry is ideal for portable or space-constrained enclosures housing 34-pin high-speed bus connections.
Why does the SFM-117-T2-LM-D-A-P include both assist posts and a polarization peg, and how do they differ?
The through-hole assist posts (A option) anchor the SMT connector mechanically into the PCB, resisting lateral forces during repeated 34-pin mating cycles rated at 500 or more engagements. The separate polarization peg (P option) is a physical key that ensures the dual-row connector seats only in the correct orientation, preventing the reverse-insertion damage that can destroy 34 signal lines in a single misalignment event.
For a compact industrial control module, how does the SFM-117-T2-LM-D-A-P compare to a wire-to-board connector with the same pin count?
Unlike a wire-to-board connector, the SFM-117-T2-LM-D-A-P mates directly to a header on a second PCB, eliminating cable mass and reducing assembly time in a 34-pin dual-row at 1.27 mm pitch format. The board-to-board approach supports signal speeds up to 10 Gbps in the SFM series and achieves a lower vertical profile than most wire harness solutions, which is critical when the enclosure depth is limited to under 20 mm.
