What are the key features of TFC-109-02-FM-D-A-K?
- 18-position, 2-row configuration at 1.27 mm (0.050 inch) pitch offers a small-footprint terminal strip for low-to-medium pin count board interconnect
- Tiger Eye contact design ensures reliable low-insertion-force mating and consistent signal continuity across all 18 positions over the connector's rated life
- Polarization key (-K) physically blocks 180-degree mis-insertion, simplifying assembly of this 18-position terminal strip in mixed-connector PCB layouts
What is TFC-109-02-FM-D-A-K used for?
The TFC-109-02-FM-D-A-K targets compact PCB interface applications in industrial sensors, small embedded controllers, and consumer electronic modules where 18 signals must be routed between boards at 1.27 mm pitch. Its polarization key reduces assembly defects when multiple similar connectors are present on the same PCB. The cost-effective TFC series construction delivers the Tiger Eye reliability needed for moderate-cycle applications without the cost premium of high-cycle connectors.

Frequently Asked Questions
How many contacts does the TFC-109-02-FM-D-A-K carry, and how are they arranged?
The TFC-109-02-FM-D-A-K carries 18 contacts split across 2 rows at 1.27 mm (0.050 inch) pitch, with 9 contacts per row, forming a compact rectangular terminal strip that occupies approximately 11.4 mm of board length.
Which small-form-factor embedded designs benefit from the 18-position TFC terminal strip with a polarization key?
This 18-position, 1.27 mm pitch terminal strip suits IoT edge nodes, compact motor driver daughter cards, and industrial sensor interface boards where 18 signals need reliable PCB-to-PCB routing within a tight footprint, and where the -K polarization key prevents mis-mating among multiple look-alike connectors rated for -55°C to +125°C operation.
What is the role of the -FM suffix in the TFC-109-02-FM-D-A-K part number?
The -FM suffix indicates a surface mount (SMT) footprint with a male contact gender, meaning the TFC-109-02-FM-D-A-K is soldered flat to the PCB rather than through-hole mounted, enabling a lower profile and compatibility with reflow solder processes used in modern SMT production lines handling 1.27 mm pitch connectors.
Is the TFC-109-02-FM-D-A-K a viable lower-cost alternative to Samtec FLE or SFM 18-position connectors?
Yes, the TFC series provides the same 1.27 mm pitch and Tiger Eye contact geometry as the FLE and SFM series but at a reduced unit cost, making the 18-position TFC-109-02-FM-D-A-K a practical choice for designs that do not require the 10 µin gold mating finish or high-cycle ratings above 100 mates.
