Key Features
- 92-position dual-row layout at 1.27 mm (0.050") pitch enabling extremely high signal density on surface mount PCBs
- High-reliability precision machined contacts with low insertion force rated for repeated mating cycles
- SMT footprint with keying feature (K suffix) preventing incorrect mating orientation for error-free assembly
Applications
The SFM-146-02-H-D-A-K is suited for high-density board-to-board interconnects in FPGA carrier boards, test fixtures, and compact embedded systems where 92-pin dual-row connectivity at 1.27 mm pitch is required. The keying feature makes it especially valuable in production environments and field-serviceable equipment where correct connector orientation must be enforced mechanically.

Frequently Asked Questions
What does the K suffix in SFM-146-02-H-D-A-K indicate about this connector?
The K suffix indicates a keying feature that physically prevents incorrect mating orientation. This mechanical polarization ensures that the 92-position dual-row connector at 1.27 mm pitch cannot be plugged in backwards, reducing assembly errors in high-volume production and field service applications.
What current and voltage ratings are typical for SAMTEC SFM series 0.050-inch pitch socket strips?
SAMTEC SFM series connectors at 1.27 mm (0.050 inch) pitch are typically rated for 1 A per contact and up to 150 V AC/DC. These ratings make the SFM-146-02-H-D-A-K appropriate for low-power signal connections across 92 positions in digital and mixed-signal PCB designs.
When should an engineer choose SFM-146-02-H-D-A-K over a higher-pitch dual-row socket such as a 2.54 mm connector?
The SFM-146-02-H-D-A-K at 1.27 mm pitch fits 92 positions into roughly half the board footprint of an equivalent 2.54 mm pitch connector. Designers choose it when PCB area is constrained and signal count exceeds 80 pins, such as in compact FPGA daughter cards or high-channel-count data acquisition modules.
