Key Features
- 38 positions in dual-row layout at ultra-fine 0.050 inch (1.27 mm) pitch
- High-reliability socket strip design for repeated mating cycles in demanding applications
- Surface mount (SM) termination for automated SMT assembly compatibility
- Polarization (P) feature prevents incorrect mating on dual-row 0.050 inch connectors
- Gold-plated contacts provide low contact resistance across thousands of mate/unmate cycles
- Dual-row (D) configuration maximizes pin density in minimal PCB footprint
Applications
The SFM-119-02-SM-D-A-P is ideal for high-density board-to-board mating systems in test and measurement equipment, data communications hardware, and medical electronics where precise signal integrity is required on 0.050 inch pitch interfaces. Its dual-row socket strip format is commonly used as the receptacle half of mezzanine board stacking assemblies and FPGA evaluation board interconnects. The polarized design helps prevent assembly errors in multi-connector system builds.

Frequently Asked Questions
What pitch does the SFM-119-02-SM-D-A-P use, and how does it compare to standard 0.100 inch connectors?
The SFM-119-02-SM-D-A-P uses a 0.050 inch (1.27 mm) pitch, which is half the spacing of standard 0.100 inch connectors, allowing 38 positions to fit in approximately the same board length that a 19-position standard-pitch connector would occupy.
How does the polarization (P) option prevent assembly errors when using this 38-position dual-row socket?
The P polarization feature introduces a mechanical key that allows only one correct mating orientation for the 38-position dual-row connector, protecting sensitive PCB assemblies from damage caused by reversed or offset insertion in multi-connector builds.
Which design scenarios call for a high-reliability 0.050 inch pitch surface mount socket like the SFM-119-02-SM-D-A-P?
Test and measurement rack systems, FPGA daughter cards, medical imaging modules, and data communications line cards requiring 38-signal interfaces at 0.050 inch pitch rely on high-reliability socket strips for mating cycles that may exceed 500 or more insertions.
Can the SFM-119-02-SM-D-A-P be paired with SAMTEC TFM series headers for a complete board stack?
Yes, SAMTEC SFM series 0.050 inch pitch socket strips are designed to mate with SAMTEC TFM series headers, creating a matched 38-position dual-row 0.050 inch pitch board stack with guaranteed contact normal force and gold-over-nickel finish compatibility.
