Key Features
- 52-position dual-row terminal strip at 0.050-inch (1.27 mm) pitch delivering high-density contact count in a cost-effective Tiger Eye design
- Floating-mount (FM) construction compensates for PCB misalignment, reducing mechanical stress on solder joints during mating and thermal cycling
- Tape-and-reel (TR) packaging with kinked tails enables automated SMT pick-and-place assembly with superior solder joint retention
Applications
The TFC-126-02-FM-D-A-K-TR is used in cost-sensitive high-density PCB designs such as consumer electronics modules, IoT gateway boards, and industrial sensor interfaces where 52 contacts at 0.050-inch pitch must be surface-mount terminated reliably. The floating-mount feature accommodates PCB-to-PCB alignment tolerances in stacked or mezzanine board configurations. Tape-and-reel packaging supports automated high-volume production at competitive per-unit connector cost.

Frequently Asked Questions
How many contacts does TFC-126-02-FM-D-A-K-TR provide and at what pitch, compared to a standard 0.100-inch connector?
The TFC-126-02-FM-D-A-K-TR provides 52 contacts at 0.050-inch (1.27 mm) pitch in a dual-row layout, achieving the same contact count in roughly half the linear board space required by an equivalent 0.100-inch pitch connector, making it a strong choice for space-constrained module-to-carrier designs.
What alignment advantage does the floating-mount (FM) design of TFC-126-02-FM-D-A-K-TR provide during board-to-board mating?
The floating-mount design on TFC-126-02-FM-D-A-K-TR allows lateral movement of approximately ±0.3 mm to ±0.5 mm between mated connector halves, accommodating cumulative PCB fabrication and assembly tolerances across the 52-pin dual-row 0.050-inch pitch footprint and preventing solder joint stress during plug-in.
In what cost-sensitive applications is TFC-126-02-FM-D-A-K-TR preferred over premium high-reliability SMT sockets?
TFC-126-02-FM-D-A-K-TR is preferred in consumer IoT modules, entry-level industrial sensor boards, and education/prototyping platforms where a 52-position 0.050-inch pitch connection is needed at lower cost per connector, and where the mating cycle count and environmental severity do not justify the higher price of premium high-reliability alternatives.
How do the kinked tails (K suffix) on TFC-126-02-FM-D-A-K-TR affect pull-out strength after reflow soldering?
The kinked tails on TFC-126-02-FM-D-A-K-TR mechanically anchor each of the 52 pins into the PCB pad solder fillet, increasing axial pull-out strength significantly compared to straight SMT tails. This improvement in joint integrity is especially valuable at 0.050-inch pitch where individual pad areas are small and joint quality directly affects long-term reliability.
