Key Features
- 40-position dual-row Tiger Eye terminal strip with 0.050" (1.27 mm) pitch for high-density vertical surface-mount PCB layouts
- 30 µin gold over nickel contact finish providing superior corrosion resistance and reliable mating in signal applications
- Low-contact-force (LC) design reduces insertion force for repeated mating cycles and delicate mating pin protection
- Split board lock mounting option improves mechanical retention and prevents connector movement under vibration or stress
Applications
The TFM-120-02-S-D-LC is used in high-reliability board-to-board and mezzanine interconnect applications where repeated mating at 0.050" pitch is required with minimal pin wear. Its Tiger Eye contact design provides reliable signal connections in FPGA evaluation modules, RF test fixtures, and precision instrumentation where gold-plated contacts are necessary for low contact resistance. The vertical SMT profile with split board lock suits compact embedded system designs requiring mechanical stability on the PCB.

Frequently Asked Questions
What contact finish does the TFM-120-02-S-D-LC use, and how does it affect connector reliability?
The TFM-120-02-S-D-LC uses 30 µin (microinches) gold over nickel contact finish on the mating surfaces, providing excellent corrosion resistance and maintaining low contact resistance below 20 milliohms even after repeated mating cycles in humid or industrial environments.
What is the Tiger Eye contact design in the SAMTEC TFM-120-02-S-D-LC, and how does it compare to standard socket contacts?
Tiger Eye contacts use a dual-beam wiping design that makes contact on two independent points per pin, doubling the contact redundancy compared to single-beam sockets; this ensures reliable electrical connection even if one contact point is slightly contaminated, which is critical for 40-position signal connectors at 0.050" pitch.
How does the low-contact-force (LC) design of the TFM-120-02-S-D-LC benefit test fixture and modular PCB applications?
The LC (low-contact-force) design reduces the mating insertion force to approximately 50% of standard-force versions, protecting delicate 0.050" pitch pins in test fixtures cycled more than 100 times and allowing manual mating without specialized tooling or risking connector or board damage.
What is the board footprint size of the TFM-120-02-S-D-LC and how does its split board lock improve mechanical attachment?
The connector body measures 1.125 inches long by 0.225 inches wide and 0.225 inches deep, with a split board lock that engages the PCB through two retention clips, increasing pull-force resistance by up to 40% compared to connectors without board locks, improving durability in vibration-prone environments.
