Key Features
- 96-position dual-row socket strip on 0.050" (1.27 mm) pitch for high-density board-to-board interconnects
- Kinematic keying (K suffix) prevents mis-mating and ensures correct polarization during assembly
- Surface mount termination compatible with standard reflow processes up to 260°C for automated high-volume production
Applications
The SFM-148-02-L-D-A-K is designed for high-density mezzanine stacking and module expansion applications in industrial control, embedded computing, and telecommunications systems. Its 96-position dual-row layout accommodates wide parallel bus architectures, mixed power-signal configurations, and differential pair routing in compact PCB designs. The kinematic keying feature adds assembly-mistake-proofing in multi-connector designs where incorrect orientation could damage sensitive circuitry.

Frequently Asked Questions
What does the K suffix on the SFM-148-02-L-D-A-K indicate about its keying and how does this affect PCB layout?
The K suffix denotes kinematic keying, which adds a mechanical polarization feature that prevents the 96-position connector from being inserted in the wrong orientation. This requires reserving a small keying slot or post footprint — typically 1.5 mm x 1.0 mm — adjacent to the main 0.050" pitch contact array when designing the PCB land pattern, ensuring correct assembly in high-volume production.
How does the 0.050" pitch SFM-148-02-L-D-A-K compare to 0.100" pitch dual-row headers for the same 96-position requirement?
At 0.050" (1.27 mm) pitch the SFM-148-02-L-D-A-K occupies roughly 48 positions x 1.27 mm = 61 mm per row, while a 0.100" (2.54 mm) pitch equivalent would require approximately 122 mm per row — double the board length. For a 96-position count, the SFM series saves over 60 mm of PCB real estate per row, enabling more compact system designs or freeing space for additional circuitry.
Which signal types and current ratings are supported across the 96 contacts of SFM-148-02-L-D-A-K?
SAMTEC SFM series contacts are rated for approximately 0.5 A per contact at the 0.050" pitch, so across 96 positions the connector can carry mixed signal and power — for example, 80 signal pins at logic levels plus 16 power/ground contacts supplying up to 8 A total. The contacts support digital signals up to several Gbps per differential pair when routed with 100 Ω controlled-impedance traces.
