Key Features
- 4 positions in dual-row configuration at 0.050" (1.27mm) pitch for ultra-compact SMT signal interconnects
- Kinked lead (A-K) surface mount termination improves solder standoff and joint quality during standard reflow up to 260°C
- Gold-plated contacts ensure low contact resistance and long mating cycle life in high-reliability embedded applications
Applications
The SFM-102-02-S-D-A-K is used in compact embedded systems, wearable electronics, and sensor modules requiring a minimal-footprint 4-pin dual-row interconnect at 0.050" pitch. Its small size makes it suited for mezzanine board attachment in medical devices, portable instrumentation, and IoT sensor nodes where PCB area is at a premium.

Frequently Asked Questions
What is the contact pitch of SFM-102-02-S-D-A-K and how does it affect the PCB footprint versus a 0.100" connector?
The SFM-102-02-S-D-A-K uses a 0.050" (1.27 mm) contact pitch, which is half of the standard 0.100" grid. This reduces the connector's PCB footprint by approximately 50% compared to an equivalent 4-position 0.100" socket, making it valuable in compact IoT sensors, wearable modules, and small mezzanine interconnect designs where every square millimeter of board space counts.
In which high-reliability use cases is the SFM-102-02-S-D-A-K preferred over a standard header socket?
The SFM-102-02-S-D-A-K is preferred in applications requiring reliable performance over many mating cycles, such as medical diagnostic modules, mil-aero sensor interfaces, and test-fixture docking systems. Its gold-plated contacts maintain low contact resistance — typically below 50 mOhm — across hundreds of insertions, outperforming standard tin-plated headers in long-service-life designs.
Can SFM-102-02-S-D-A-K be wave-soldered, or is it strictly a reflow-only component?
The SFM-102-02-S-D-A-K is a surface mount connector designed for reflow soldering, with its kinked leads providing a controlled standoff to hold the part flat during reflow at peak temperatures up to 260°C per J-STD-020 profile. Wave soldering is not recommended for this SMT part as the lead geometry is optimized for paste-and-reflow assembly rather than a molten wave process.
