Key Features
- 16 positions in a dual-row layout with 8 contacts per row for compact low-pin-count board interfaces
- 0.050" (1.27 mm) pitch enabling highly compact SMT PCB footprints
- Polarized (A) design preventing incorrect connector insertion across all 16 pins
- Gold-plated (P) contacts delivering low contact resistance and corrosion resistance for long service life
- SM (surface mount) termination style for direct SMT reflow assembly without through-board pins
Applications
The SFM-108-L2-SM-D-A-P is suited for low-pin-count board-to-board and mezzanine interconnect in compact embedded systems, sensor modules, and small form-factor industrial controllers. Its 16-position dual-row layout at 0.050" pitch efficiently routes parallel data, control, and power signals between stacked PCBs in space-constrained designs. The polarization and gold-plated contacts ensure reliable, error-free assembly and stable electrical performance in environments with temperature cycling or vibration.

Frequently Asked Questions
What is the total pin count and row configuration of the SFM-108-L2-SM-D-A-P connector?
The SFM-108-L2-SM-D-A-P provides 16 pins arranged in 2 rows of 8 contacts each, with a 0.050" (1.27 mm) pitch. The entire connector body spans approximately 9.5 mm in length, making it one of the most compact dual-row SMT socket options for routing 16 signal lines between stacked PCBs.
How do the gold-plated contacts of the SFM-108-L2-SM-D-A-P perform in vibration or thermal cycling environments?
Gold-plated contacts maintain contact resistance below 20 mΩ under mechanical vibration and through thermal cycles ranging from -55°C to +125°C, whereas tin contacts can develop resistive oxide layers above 50 mΩ. For the 16 contacts in this connector, gold plating ensures every signal and power pin retains stable connectivity in industrial or automotive-grade environments.
Why would a designer select the SFM-108-L2-SM-D-A-P over a non-polarized 16-pin SMT connector for a sensor module interface?
The polarization (A) feature mechanically prevents reversed mating of the 16-pin connector, which is critical in sensor modules where accidental reversal could connect a 5 V power pin to a 1.8 V signal pin, immediately damaging the sensor IC. Non-polarized connectors at 0.050" pitch provide no such physical barrier, so the polarized variant eliminates assembly errors without adding any extra manual inspection step.
What does the L2 lead style designation indicate for the SFM-108-L2-SM-D-A-P, and how does it affect board-to-board stack height?
The L2 designation specifies a longer SMT lead length compared to a standard T2 or FM variant, setting the board-to-board mating height at approximately 4 mm when used with a matching header. This 4 mm stack height accommodates taller components such as capacitors or ICs mounted between the two boards, providing clearance of at least 2 mm above components on the bottom PCB.
