Key Features
- 92-position dual-row socket strip on 0.050 inch (1.27 mm) pitch delivers exceptional contact density for high-signal-count PCB-to-PCB interfaces
- Low-mount SMT termination style with precision kinked leads ensures excellent coplanarity and solder joint reliability during reflow assembly
- High-reliability contact system rated for repeated mating cycles in demanding industrial and computing environments
Applications
The SFM-146-02-LM-D-A-K serves as the female half of high-density board-to-board interconnects in server backplanes, FPGA carrier boards, and high-speed data acquisition systems requiring 92 simultaneous signal connections. The low-mount surface-mount profile keeps the mated stack height minimal, making it suitable for space-constrained enclosures in medical instrumentation and embedded computing platforms. Its 0.050 inch pitch supports signal integrity at bus speeds exceeding 100 MHz across all 92 positions.

Frequently Asked Questions
How does the SFM-146-02-LM-D-A-K's low-mount termination affect the mated stack height compared to standard SFM variants?
The LM (low-mount) termination style of the SFM-146-02-LM-D-A-K keeps the SMT solder tails close to the board, resulting in a mated board-to-board stack height of approximately 4 mm to 6 mm depending on the mating pin header. This is typically 2 mm to 3 mm lower than standard mount variants, which is critical for compact enclosures where total PCB stack height must remain under 10 mm.
For a server backplane carrying 92 signal lines, what current rating should I plan for with the SFM-146-02-LM-D-A-K?
Each contact in the SFM-146-02-LM-D-A-K is rated for approximately 1 A continuous current at the standard 0.050 inch pitch. For a backplane carrying 92 signals, the connector can handle up to 92 A total if distributed evenly, though typical signal-only designs operate well below this at 100 mA to 500 mA per contact to maintain signal integrity above 100 MHz.
Which SAMTEC pin header mates with the SFM-146-02-LM-D-A-K and how do I specify the correct part number?
The SFM-146-02-LM-D-A-K mates with SAMTEC TSM or TMM series dual-row pin headers at 0.050 inch pitch with 46 positions per row (92 total). Select the mating part based on required stacking height (4 mm to 11 mm range available) and pin length. The mating header must also be specified with the A (polarization) option to match the -A-K keying on this socket.
