Key Features
- 32-position dual-row socket on 0.050" (1.27 mm) pitch with gold-over-nickel mating contacts for reliable low-resistance connections
- Split board-lock (LC) retention feature provides mechanical locking to prevent accidental mating separation under vibration
- RoHS-compliant (Pb-free) construction with tin-over-nickel termination finish compatible with standard SAC solder reflow
Applications
The SFM-116-02-S-D-LC is designed for high-density mezzanine and daughter-card interconnections in industrial, embedded computing, and ruggedized environments where a 32-position 0.050" pitch socket with mechanical board-locking is required. The split board-lock feature provides added retention force against vibration and shock, making it well suited for transportation, defense, and industrial automation platforms. Gold-over-nickel contacts ensure long-term signal integrity across many mating cycles and in environments prone to oxidation.

Frequently Asked Questions
What contact finish does the SFM-116-02-S-D-LC use and why does it matter for connector reliability?
The SFM-116-02-S-D-LC uses gold-over-nickel finish on mating contacts, which provides excellent corrosion resistance and a stable low-contact-resistance interface across many mating cycles. Gold plating is particularly important in fine-pitch 0.050 inch connectors where contact force is lower, ensuring reliable electrical performance even in humid or mildly corrosive environments.
How does the split board-lock feature on the SFM-116-02-S-D-LC improve mechanical performance in vibrating environments?
The LC (split board-lock) option mechanically anchors the 32-position socket to the PCB through retention pegs that engage the board, significantly increasing pull-out resistance compared to standard SMT solder joints alone. This is critical in transportation, industrial automation, and defense applications where the connector may experience sustained vibration loads exceeding 10 g, preventing intermittent disconnection.
What are the body dimensions of the SFM-116-02-S-D-LC and how do they influence PCB layout planning?
The SFM-116-02-S-D-LC has a body length of 0.955 inch, a depth of 0.185 inch, and a breadth of 0.145 inch, establishing the keep-out zone around the 32 contact pads on a 0.050 inch pitch. PCB designers must maintain clearance within these dimensions for the board-lock peg holes and ensure adjacent components respect the 0.185 inch mated height to avoid mechanical interference with the daughtercard.
