Key Features
- 54-position dual-row terminal strip with 0.050" (1.27 mm) pitch enabling high pin-count interfaces in minimal PCB space
- Tiger Eye friction-mating contact provides reliable connection without latching hardware in cost-sensitive designs
- Kinked (K) through-hole tail locks connector during soldering, preventing movement across 27 positions per row
- FM (friction-mating) designation ensures cost-effective board-to-board mating compatible with standard 0.050" pitch headers
Applications
The TFC-127-02-FM-D-A-K serves high-density board-to-board signal interconnection needs in embedded computing, telecom line cards, and industrial control systems requiring 54 positions at 0.050" pitch. The Tiger Eye friction-mating design enables repeated mating without secondary locking mechanisms, streamlining field replacement of mezzanine boards. Kinked tails provide robust mechanical holding during reflow or wave soldering processes.

Frequently Asked Questions
How many positions does the TFC-127-02-FM-D-A-K provide and at what pitch?
The TFC-127-02-FM-D-A-K offers 54 positions arranged in a dual-row configuration at 0.050" (1.27 mm) pitch, with 27 positions per row. This high-density arrangement supports numerous signal or mixed signal/power lines on a compact PCB footprint suitable for embedded and telecom applications.
What does the FM suffix mean on the TFC-127-02-FM-D-A-K and how does it affect mating?
The FM suffix designates a friction-mating contact style on the TFC-127-02-FM-D-A-K, meaning the 54-position connector mates using contact spring force alone without secondary latching. This design reduces part cost and assembly complexity while still providing adequate retention force for board-to-board interfaces in low-vibration environments.
Why is the kinked tail (K) important for the TFC-127-02-FM-D-A-K during PCB assembly?
The kinked through-hole tail on the TFC-127-02-FM-D-A-K physically anchors the 54-position connector to the PCB before soldering, preventing any lateral or rotational shift across the 1.27 mm pitch rows during wave or hand solder operations. Stable pre-solder positioning reduces rework rates in production.
In which system designs is the TFC-127-02-FM-D-A-K a preferred interconnect over higher-cost alternatives?
The TFC-127-02-FM-D-A-K is preferred in cost-sensitive designs requiring 54-pin dual-row 0.050" pitch interconnects, such as industrial control backplanes, telecom daughter cards, and embedded computing modules where Tiger Eye contact reliability is needed but expensive latching or high-cycle-life contact systems would increase BOM cost unnecessarily.
