Key Features
- 40 positions in dual-row configuration on 0.050" (1.27 mm) pitch for high-density SMT layouts
- Gold (10 µin) over Nickel (50 µin) contact finish on mating surfaces for reliable signal integrity
- Surface mount termination with positioning pin for accurate PCB placement during reflow
- RoHS compliant construction with matte tin finish on termination contacts
- Compact body dimensions of 1.125" length x 0.185" depth suitable for space-constrained designs
Applications
The SFM-120-T2-L-D-A-P is well suited for high-density board-to-board and board-to-mezzanine interconnect in telecom, networking, and industrial control systems. Its fine 0.050 inch pitch and dual-row layout allow engineers to maximize signal density while keeping the PCB footprint minimal. The positioning pin feature simplifies pick-and-place assembly in high-volume SMT production.

Frequently Asked Questions
How does the 0.050 inch pitch of SFM-120-T2-L-D-A-P compare to standard 0.100 inch pitch socket strips for high-density PCB designs?
The SFM-120-T2-L-D-A-P uses a 0.050 inch (1.27 mm) pitch, half the spacing of standard 0.100 inch pitch connectors, allowing 40 pins in a dual-row body measuring only 1.125 inch long. This makes it ideal for space-constrained boards where signal density per unit area is critical.
What contact plating does SFM-120-T2-L-D-A-P use, and how does it affect mating cycle life in telecom equipment?
Mating contacts are finished with Gold (10 µin) over Nickel (50 µin), providing low contact resistance and corrosion resistance through hundreds of mating cycles. The gold finish is a standard requirement for telecom and networking connectors operating over wide temperature ranges.
Is SFM-120-T2-L-D-A-P RoHS compliant, and does it meet lead-free assembly process requirements?
Yes, the SFM-120-T2-L-D-A-P is RoHS compliant with matte tin (Sn) termination finish over a nickel barrier, compatible with standard lead-free reflow soldering profiles up to 260°C peak temperature used in modern SMT production lines.
How does the positioning pin on SFM-120-T2-L-D-A-P assist high-volume SMT assembly compared to connectors without this feature?
The built-in positioning pin registers the connector body to a matching PCB hole, reducing placement offset during automated pick-and-place across all 40 pins in the dual-row layout. This prevents the body from floating during reflow, which is critical for maintaining coplanarity across all pads.
