What are the key features of TFM-142-02-FM-D-RA?
- 84 total pins (42 per row, dual-row) on a 0.050-inch (1.27 mm) pitch deliver very high connection density in a compact footprint
- Tiger Eye contact system provides high-reliability mating retention and low contact resistance across thousands of insertion cycles
- Right-angle (RA) orientation routes all 84 pins horizontally from the board edge, minimising connector height above the PCB
- High-reliability terminal strip construction suits military, aerospace, and industrial instrumentation applications
What is TFM-142-02-FM-D-RA used for?
The TFM-142-02-FM-D-RA is ideal for high-density backplane, daughter-card, and cable-to-board connections in military, aerospace, and industrial instrumentation where 84 reliable signal paths are needed at a compact 0.050-inch pitch. Its right-angle mounting allows boards to be connected at 90 degrees, simplifying cable management and front-panel access in rack-mounted and embedded systems. Tiger Eye contact technology ensures consistent mating force and signal integrity across the full service life of the assembly.

Frequently Asked Questions
How many pins does the TFM-142-02-FM-D-RA provide, and what is the contact pitch?
The TFM-142-02-FM-D-RA provides 84 pins arranged across 2 rows of 42 contacts each, with a 0.050-inch (1.27 mm) centre-to-centre pitch. This dual-row configuration packs a large number of signal connections into a narrow board footprint, making it a practical choice for high-density cable-to-board or mezzanine interconnects.
In which high-reliability platforms does SAMTEC's Tiger Eye contact system in the TFM-142-02-FM-D-RA excel?
The Tiger Eye contact system used in the TFM-142-02-FM-D-RA is engineered for military electronics, aerospace avionics, and rugged industrial instrumentation that demand reliable interconnects across thousands of mating cycles. The 84 pins maintain consistent contact resistance over the rated temperature range of -55 °C to +125 °C, safeguarding signal integrity in thermally challenging environments.
How does the right-angle orientation of the TFM-142-02-FM-D-RA benefit rack-mount and chassis PCB layouts?
With right-angle (RA) termination, the TFM-142-02-FM-D-RA aligns all 84 pins horizontally so cables or mating connectors exit perpendicular to the PCB surface rather than rising above it. This reduces the vertical clearance requirement, allowing boards to be spaced more closely in rack or chassis assemblies, and keeps the 0.050-inch pitch connector footprint narrow for dense multi-connector layouts.
How does the TFM-142-02-FM-D-RA compare to a single-row 84-pin alternative for connector selection?
The dual-row layout of the TFM-142-02-FM-D-RA fits 84 pins into roughly half the board-edge length that a single-row connector would require at the same 0.050-inch pitch, saving significant PCB perimeter space. The two-row arrangement also improves mechanical stability during cable mating and reduces the connector's moment arm, lowering stress on the solder joints at the 42 contacts per row.
