Key Features
- 26-position dual-row SMT socket with 0.050 inch (1.27 mm) pitch and polarization key for foolproof mating
- Beryllium copper contacts with 10 µin gold over 50 µin nickel deliver low contact resistance and high spring-force retention
- Female socket strip design for repeated mate/unmate cycles in test, debug, and modular board applications
Applications
The SFM-113-02-L-D-A-P is used in high-reliability embedded systems, daughter-card interfaces, and modular computing platforms where a compact 0.050 inch pitch dual-row socket is required. Its beryllium copper contacts with gold mating surface provide stable electrical performance across thousands of insertion cycles, making it ideal for field-replaceable modules and test fixture applications. Polarization prevents reverse insertion, which is critical in aerospace electronics, medical devices, and industrial control boards.

Frequently Asked Questions
What contact material and finish does the SFM-113-02-L-D-A-P use for reliable mating performance?
The SFM-113-02-L-D-A-P uses beryllium copper contacts with 10 µin gold plated over 50 µin nickel on the mating surface, providing contact resistance below 20 milliohms. The termination side uses matte tin over nickel barrier for compatibility with standard solder reflow at up to 260°C.
How does the polarization feature of the SFM-113-02-L-D-A-P protect against assembly errors?
The polarization key on the SFM-113-02-L-D-A-P physically prevents reverse or misaligned insertion of the mating plug connector. This is critical for dual-row 26-position connectors where incorrect mating could apply voltage to wrong pins, potentially damaging circuits operating at 3.3 V or 5 V logic levels.
For which industries is the SFM-113-02-L-D-A-P a suitable choice, and what test conditions must it survive?
The SFM-113-02-L-D-A-P is rated for high-reliability applications including aerospace, defense, and industrial automation. It is engineered to survive thermal cycling from -55°C to +125°C and withstand contact engaging forces typical of beryllium copper springs, maintaining consistent performance across 500 or more mating cycles.
