What are the key features of TFC-109-02-F-D-A-K?
- 18 positions in a dual-row 0.050" (1.27 mm) pitch layout for low-density, compact board-to-board signal connections
- Polarization key (-K) prevents incorrect connector orientation during mating, reducing assembly errors in automated and manual production
- Tiger Eye cost-effective contact design delivers reliable signal integrity at low insertion force for repeated mating cycles
What is TFC-109-02-F-D-A-K used for?
The TFC-109-02-F-D-A-K is suited for low-pin-count board-to-board interconnects in compact embedded controllers, small IoT modules, and sensor interface daughter cards where 18 signal lines must be connected reliably on a 0.050" pitch. The polarization key feature makes this connector particularly appropriate for field-replaceable or hot-swappable card designs where incorrect mating must be prevented to avoid circuit damage.

Frequently Asked Questions
What polarization feature does the TFC-109-02-F-D-A-K include, and why does it matter?
The TFC-109-02-F-D-A-K includes a -K polarization key that physically prevents the connector from being mated in the incorrect orientation. On an 18-position, 0.050" pitch dual-row connector, an incorrect mating could reverse power and signal pins, causing circuit damage. The keying feature eliminates this risk in both automated assembly and field maintenance scenarios.
How many positions does the TFC-109-02-F-D-A-K offer, and for which signal counts is it best suited?
The TFC-109-02-F-D-A-K offers 18 total positions in 2 rows on a 0.050" (1.27 mm) pitch. It is best suited for applications needing 18 or fewer signal lines, such as SPI or I2C buses with auxiliary GPIO lines, small sensor interface cards, or compact module sub-boards that require a reliable but cost-effective 18-position interconnect.
How does the 0.050" pitch of the TFC-109-02-F-D-A-K contribute to PCB space savings compared to standard 0.1" pitch connectors?
At 0.050" (1.27 mm) pitch, the TFC-109-02-F-D-A-K occupies half the linear board space per contact compared to a standard 0.1" (2.54 mm) pitch connector carrying 18 signals. This means the 18-position dual-row strip fits within approximately 0.45 inches (11.4 mm) of board length, making it effective for designs where multiple connectors must fit along a narrow PCB edge.
In which embedded IoT or control board scenarios does the TFC-109-02-F-D-A-K provide the best fit?
The TFC-109-02-F-D-A-K fits best in embedded IoT scenarios where a small sensor node or actuator board connects to a central controller via 18 lines carrying power rails up to typical connector current ratings, SPI or UART data signals, and discrete I/O lines. The keying feature and cost-effective Tiger Eye contacts make it practical for modular system designs that may require field replacement of daughter cards while preventing mismatement damage.
