What are the key features of TFC-126-02-FM-D-A-K?
- 52-position dual-row female-male (FM) configuration at 0.050" (1.27 mm) pitch for flexible mid-density board interconnect
- Tiger Eye dual-beam contact ensures consistent mating force and contact resistance under 20 mΩ over 200+ cycles
- Cost-effective terminal strip design reduces total connector BOM cost in volume production without sacrificing reliability
What is TFC-126-02-FM-D-A-K used for?
The TFC-126-02-FM-D-A-K is used in mid-density signal routing applications such as embedded processor boards, sensor interface modules, and test-and-measurement equipment that require 52 reliable signal paths in a compact PCB footprint. The female-male dual-row layout with 1.27 mm pitch is well suited for mezzanine card stacking and daughter-card attachment designs. Its Tiger Eye contacts perform consistently across the full industrial temperature range, supporting deployment in harsh environments.

Frequently Asked Questions
What does the FM designation mean for the TFC-126-02-FM-D-A-K and how does it affect mating compatibility?
The FM suffix indicates a female-male contact arrangement on the TFC-126-02-FM-D-A-K, meaning the housing carries both receptacle and pin contacts within the 52-position dual-row body. This configuration allows direct board-to-board mating at 0.050 inch (1.27 mm) pitch without a separate mating connector, saving PCB stack height and enabling compact mezzanine module attachment in enclosures with limited vertical clearance.
Which embedded computing module designs benefit most from the 52-position count of the TFC-126-02-FM-D-A-K?
Embedded processor daughter cards and sensor interface modules that need 26 signal lines per row are ideal candidates for the TFC-126-02-FM-D-A-K. Its 52 total positions at 1.27 mm pitch span a connector body under 45 mm long, fitting neatly on standard PC/104 or compact carrier boards. Applications include industrial IoT gateways, motor encoder interfaces with up to 16 channels, and FPGA mezzanine modules requiring mixed power-and-signal connectivity.
When would a design team choose the TFC-126-02-FM-D-A-K over a 0.100 inch pitch alternative for a 52-circuit interface?
When PCB real estate is scarce and the connector body must fit within a 45 mm width, the TFC-126-02-FM-D-A-K at 1.27 mm pitch occupies roughly half the footprint of a 0.100 inch pitch 52-position strip. The Tiger Eye contacts rated from -55°C to +125°C also make it suitable for industrial or automotive-adjacent environments where a standard 0.100 inch strip might not meet thermal requirements. Volume price per circuit is comparable, making it cost-neutral at quantities above 1,000 pieces.
