Key Features
- 56-position dual-row connector at 0.050 inch (1.27 mm) pitch for high-density module-to-board signal routing
- FM (flex-cable) termination style accommodates flexible ribbon cable attachment for low-profile interconnect solutions in constrained PCB spaces
- Keying feature (K suffix) prevents mis-mating, ensuring correct connector orientation during PCB assembly of high-pin-count dual-row interfaces
Applications
The SAMTEC TFC-128-02-FM-D-A-K is designed for high-density signal applications in embedded computing, FPGA development boards, and test and measurement equipment requiring 56-pin flex-cable to PCB connections at 0.050 inch pitch. Its compact dual-row format and flex termination support use in space-constrained instrumentation, industrial controllers, and mezzanine card assemblies.

Frequently Asked Questions
How many positions does the TFC-128-02-FM-D-A-K have, and what is its contact pitch?
The TFC-128-02-FM-D-A-K provides 56 positions in a dual-row arrangement at 0.050 inch (1.27 mm) pitch, with 28 contacts per row, making it a high-density interconnect solution for embedded module and FPGA mezzanine card applications.
What does the FM suffix indicate for the TFC-128-02-FM-D-A-K and when is it preferable?
The FM suffix specifies a flex-cable mating interface on the TFC-128-02-FM-D-A-K, allowing termination to flexible ribbon cables rather than rigid PCB headers. This is preferable in applications where board-to-board routing must navigate tight mechanical constraints, such as compact industrial instruments with separated 56-pin signal planes.
What design scenarios benefit from using a keyed 56-position connector like the TFC-128-02-FM-D-A-K over an un-keyed alternative?
A keyed 56-position connector like the TFC-128-02-FM-D-A-K reduces assembly defect risk in dual-row 0.050 inch pitch interfaces by mechanically blocking incorrect plug-in orientation, particularly important in high-volume production lines where 56 misaligned contacts could damage signals in FPGA, DSP, or data acquisition boards.
