Key Features
- Tiger Eye bifurcated contact design provides 2 contact points per pin for superior vibration resistance and reliable connection across 500+ mating cycles
- Gold-over-nickel (Au/Ni) contact finish ensures contact resistance below 20 mΩ and long-term corrosion resistance in harsh environments
- Right-angle (RA) dual-row receptacle at 1.27 mm (0.050 inch) pitch allows horizontal cable exit for space-constrained PCB edge routing
- RoHS compliant Pb-free construction with 1-week factory lead time for quick-turn prototyping and production procurement
Applications
TFM-120-01-L-D-RA is used for high-reliability board-to-board and board-to-cable connections in test and measurement equipment, medical imaging systems, and military-grade electronics where 500+ mating cycles and gold-plated contacts are required at 1.27 mm pitch. Its right-angle orientation and Tiger Eye contacts also make it well suited for FPGA mezzanine card interconnects, RF module interfaces, and data acquisition systems needing low-profile horizontal connector profiles.

Frequently Asked Questions
How many mating cycles does TFM-120-01-L-D-RA support and what contact finish enables this?
TFM-120-01-L-D-RA supports up to 500 mating cycles thanks to its gold-over-nickel (Au/Ni) contact finish. Gold plating provides superior wear resistance and maintains contact resistance below 20 mΩ across all cycles, meeting requirements for test fixtures and high-cycle lab instrumentation used in production environments.
What pitch and row configuration does TFM-120-01-L-D-RA use for high-density PCB connections?
TFM-120-01-L-D-RA uses 1.27 mm (0.050 inch) pitch in a dual-row right-angle receptacle layout with 40 positions total (20 per row). This configuration achieves high signal density of approximately 16 contacts per centimeter per row, enabling high pin count interfaces in compact PCB footprints for FPGAs and multi-channel data acquisition systems.
What advantage does the Tiger Eye contact design give TFM-120-01-L-D-RA in vibration-prone or shock environments?
The Tiger Eye bifurcated spring contact maintains 2 independent contact points per pin, so even if one contact deflects under vibration loads up to 20g, the second contact maintains electrical continuity. This dual-point design keeps signal integrity intact in aerospace and industrial automation environments where standard single-wipe contacts would lose contact under shock.
For a right-angle FPGA mezzanine interface, when is TFM-120-01-L-D-RA chosen over a vertical dual-row connector?
TFM-120-01-L-D-RA is chosen when the cable or daughter card must exit horizontally parallel to the PCB surface, reducing connector height profile to under 7 mm above the PCB. Vertical dual-row connectors add 10 mm to 15 mm of height, violating chassis clearance constraints in 1U rack systems and compact embedded controllers with less than 20 mm internal PCB-to-cover clearance.
