What are the key features of TFM-127-12-F-D?
- 54 total pins (27 per row, dual-row) on a 0.050-inch (1.27 mm) pitch maximise connection density in a compact board-edge footprint
- Tiger Eye contact system ensures reliable mating retention and consistent low contact resistance across thousands of insertion cycles
- Female contact orientation mates with standard SAMTEC male pin headers for secure, low-profile board-to-board interconnects
- Suitable for operating temperatures of -55 °C to +125 °C in rugged industrial, military, and avionics applications
What is TFM-127-12-F-D used for?
The TFM-127-12-F-D is designed for high-reliability board-to-board and daughter-card interconnect applications in military electronics, industrial instrumentation, and communications equipment where 54 dependable signal connections are needed at a compact 0.050-inch pitch. Its Tiger Eye contact technology maintains consistent electrical performance across repeated mating cycles, suiting modular systems that require frequent board swaps or field servicing. The dual-row female strip mates with standard SAMTEC pin headers to form a mechanically secure and electrically reliable low-profile interconnect.

Frequently Asked Questions
How many pins does the TFM-127-12-F-D provide, and what is the contact pitch?
The TFM-127-12-F-D offers 54 pins arranged in 2 rows of 27 contacts each, with a 0.050-inch (1.27 mm) centre-to-centre pitch. This dual-row layout maximises connection density along the board edge and is well suited to daughter-card and mezzanine applications requiring a large number of signals in a compact, low-profile connector.
In which rugged or modular systems does the Tiger Eye contact technology of the TFM-127-12-F-D excel?
The Tiger Eye contacts in the TFM-127-12-F-D are engineered for military, aerospace, and rugged industrial platforms that require reliable 54-pin interconnects maintained across thousands of mating cycles. The connector handles operating temperatures of -55 °C to +125 °C, making it suitable for thermally demanding environments found in avionics racks, embedded computing modules, and field-deployed test instruments.
How does the dual-row design of the TFM-127-12-F-D save board-edge space compared to a single-row strip?
Packing 54 pins into 2 rows at a 0.050-inch pitch means the TFM-127-12-F-D spans roughly half the board-edge length of a single-row 54-pin strip at the same pitch. This shorter connector footprint is valuable in designs where multiple connectors share the same PCB edge, and the two-row geometry also improves pull-out retention force, reducing connector tilt and solder-joint stress during mating.
How does the TFM-127-12-F-D compare to a higher-pitch 2 mm or 2.54 mm dual-row alternative for space-sensitive PCB designs?
At 0.050-inch (1.27 mm) pitch, the TFM-127-12-F-D occupies significantly less board area than a 2 mm or 2.54 mm pitch dual-row strip carrying the same 54 pins, which can be decisive in densely routed PCBs. The trade-off is that the finer pitch requires more precise PCB fabrication tolerances, but modern FR-4 boards with 0.1 mm minimum trace widths handle 0.050-inch pitch connectors reliably in volume production.
