Key Features
- Tiger Eye contact technology provides superior spring force and contact retention for reliable mating cycles at 0.050" (1.27 mm) pitch
- Split board lock mounting option delivers robust mechanical attachment, resisting vibration and mating forces on the 40-position dual-row connector
- RoHS-compliant Pb-free construction with 1-week factory lead time and 1.155 inch body length for straightforward PCB integration
Applications
The SFM-120-02-S-D-LC is well suited for board-to-board interconnects in industrial automation, robotics, and embedded computing where 40 dual-row signals must withstand vibration and repeated mating. The split board lock provides additional PCB anchoring, making it practical for applications subject to mechanical shock or board-handling stress during assembly. Its Tiger Eye contacts and 1.27 mm pitch support compact high-density designs on surface mount PCBs.

Frequently Asked Questions
What is the Tiger Eye contact feature in the SFM-120-02-S-D-LC and how does it improve reliability?
The Tiger Eye contact is SAMTEC's proprietary dual-beam contact design that provides higher and more consistent spring force than standard single-beam contacts. In the SFM-120-02-S-D-LC, this feature ensures reliable low-resistance mating across 40 dual-row positions at 1.27 mm pitch over repeated insertion cycles.
How does the split board lock on the SFM-120-02-S-D-LC benefit applications subject to mechanical vibration?
The split board lock mounting option of the SFM-120-02-S-D-LC anchors the 1.155 inch body to the PCB at 2 points, distributing lateral and axial mating forces to prevent connector rocking in vibration-prone environments such as robotics, automotive modules, and industrial motion control boards.
What is the factory lead time and body length of the SFM-120-02-S-D-LC for production planning?
The SFM-120-02-S-D-LC has a 1-week factory lead time with a body length of 1.155 inch, accommodating 40 positions at 0.050 inch (1.27 mm) pitch. The short lead time supports rapid production ramp-up, and RoHS Pb-free compliance satisfies modern environmental manufacturing standards.
