What are the key features of SFM-110-02-SM-D-A-K?
- 20-position dual-row polarized socket on 0.050" (1.27 mm) pitch with keying to prevent incorrect mating orientation
- Female contact design with high-reliability construction enables secure, repeatable board-to-board interconnection
- Surface-mount termination compatible with standard SMT reflow assembly processes on lead-free PCB lines
- Compact 0.050" pitch footprint maximizes signal density in space-constrained embedded system and mezzanine designs
What is SFM-110-02-SM-D-A-K used for?
The SFM-110-02-SM-D-A-K is designed for compact board-to-board mezzanine connections in embedded computing, instrumentation, and communication hardware requiring 20 polarized signal paths on a 0.050" pitch. The keying feature eliminates the risk of reversed connector insertion, making this socket valuable in field-serviced equipment where modules are frequently swapped. Its SMT format enables reflow assembly on standard production lines without requiring additional through-hole drilling.

Frequently Asked Questions
How does the polarized keying on the SFM-110-02-SM-D-A-K prevent mismate errors in a modular system?
The SFM-110-02-SM-D-A-K incorporates a polarized (keyed) design that physically prevents the connector from mating in the wrong orientation, protecting 20 signal contacts from mismate damage. On a 0.050" (1.27 mm) pitch with closely spaced pins, accidental reversed mating could short adjacent signals, so the polarization is essential for field-service reliability in plug-in module systems.
What is the significance of the 0.050" pitch for routing a 20-position dual-row socket on a PCB?
A 0.050" (1.27 mm) pitch means the 20-position dual-row SFM-110-02-SM-D-A-K occupies a footprint of only about 12.7 mm in length with 2 rows, roughly half the length of an equivalent 20-pin 0.1" pitch connector. This compact footprint allows engineers to place the socket on densely populated boards such as FPGA mezzanines or embedded module carriers without sacrificing 20 signal connections.
In which end-use applications is the SFM-110-02-SM-D-A-K most commonly specified?
This 20-position polarized SMT socket is commonly used in modular embedded computing systems, small-form-factor daughterboard connectors, instrumentation signal-routing boards, and communication daughtercards where 20 reliable high-density signals must be exchanged between two stacked PCBs. The polarized keying is particularly valued in field-replaceable module designs where non-technical personnel may perform board swaps.
Can the SFM-110-02-SM-D-A-K be assembled on a standard lead-free SMT reflow line?
Yes. The SFM-110-02-SM-D-A-K uses a surface-mount termination style that is compatible with standard lead-free SMT reflow soldering profiles, typically peaking at 260°C. Its SMT pads allow placement by automated pick-and-place equipment, and the 0.050" pitch requires tight placement accuracy to ensure all 20 pads align correctly with the PCB footprint during reflow.
