Key Features
- 80-position dual-row layout at 0.050-inch pitch delivers high-density signal routing on a minimal PCB footprint
- Right-angle surface-mount orientation enables low-profile daughter-card and board-edge mating configurations
- Tiger Eye contact technology provides reliable wiping-action engagement for high-cycle-count and ruggedized applications
Applications
The TFM-140-02-FM-D-RA is designed for high-density board-to-board and daughter-card interconnect in defense electronics, test and measurement systems, and industrial automation modules. Its right-angle orientation allows PCBs to stack or mate at 90 degrees while maintaining a compact board height profile. The 80-contact layout and Tiger Eye contacts support reliable signal integrity in high-pin-count FPGA, processor, and memory card assemblies across wide temperature ranges.

Frequently Asked Questions
How many signal contacts does the TFM-140-02-FM-D-RA provide, and how are they arranged?
The TFM-140-02-FM-D-RA provides 80 pins arranged in a dual-row configuration with 40 contacts per row at 0.050-inch pitch. This high-density layout consolidates a large number of signals into a single compact connector footprint, making it efficient for routing FPGA I/O banks, processor data buses, and high-density backplane interfaces on embedded computing boards.
What PCB height advantage does the right-angle orientation of the TFM-140-02-FM-D-RA provide in stacked-board designs?
The right-angle mounting directs the mating interface parallel to the board surface, significantly reducing the vertical clearance needed above the PCB compared to vertical connectors. For an 80-pin, 0.050-inch-pitch interface this allows daughter cards to engage in confined enclosures and rack-mount chassis where component height is restricted to less than 10 mm above the board plane.
Why is the Tiger Eye contact technology of the TFM-140-02-FM-D-RA preferred for defense and test-fixture applications?
Tiger Eye contacts perform a wiping action during mating that displaces surface contamination and oxide layers, maintaining reliable electrical continuity across many insertion cycles. For defense avionics and automated test equipment where the 80 pins must perform consistently from -55°C to +125°C through repeated mating events, this contact design significantly reduces intermittent connection failures compared to standard stamped contacts.
