Key Features
- Fine 0.050" (1.27mm) pitch with 82 dual-row positions enabling high-density signal routing in compact mezzanine designs
- High-reliability socket strip construction with keying features preventing incorrect mating orientation
- Surface mount termination style supporting automated SMT reflow assembly for consistent solder joint quality
Applications
The SFM-141-L2-L-D-A-K is used in high-density mezzanine board interconnects for communications modules, FPGA daughter cards, and compact embedded computing platforms where a 0.050" pitch reduces connector footprint by 50% compared to standard 0.100" solutions. Its high-reliability rating and keyed dual-row configuration make it suitable for mission-critical instrumentation and aerospace-adjacent applications requiring secure, repeatable mating.

Frequently Asked Questions
What contact pitch does the SFM-141-L2-L-D-A-K use, and how does it compare to standard 0.100" connectors?
The SFM-141-L2-L-D-A-K uses a fine 0.050" (1.27mm) pitch, which is half the spacing of standard 0.100" connectors. This halved pitch allows the same 82-position, dual-row connector to occupy roughly 50% less PCB length, enabling significantly denser board-to-board interconnects in FPGA mezzanine cards and compact embedded computing modules.
How does the keyed design of the SFM-141-L2-L-D-A-K prevent incorrect mating in dense multi-connector assemblies?
The -K suffix indicates a keyed connector variant, meaning a physical polarization feature on the housing prevents the socket from mating in the wrong orientation. In multi-connector assemblies with 82 positions and 0.050" pitch, even a 1-position offset would cause 82 signal mismatches, so the keying feature is essential for protecting sensitive FPGA and high-speed digital circuits.
What mating connector family is the SFM-141-L2-L-D-A-K designed to accept, and what is the mating cycle rating?
The SFM series is SAMTEC's high-reliability socket strip designed to mate with the TSM and TFM pin strip families at 0.050" pitch. High-reliability SAMTEC socket strips in this series are typically rated for 30 or more mating cycles, making them suitable for systems requiring periodic daughter card removal for maintenance or upgrades in test equipment and instrumentation racks.
