Applications
TFC-109-02-FM-D-A is designed for board-to-board and board-to-flex interconnects in portable medical devices, handheld test instruments, and compact embedded modules requiring 18-pin signal routing at 0.050-inch pitch. Its Tiger Eye contact design ensures reliable mating performance in vibrating or thermally cycling environments found in industrial sensor assemblies and wearable electronics. The cost-effective design makes it suitable for high-volume consumer electronics and IoT devices where minimizing connector cost per channel is a key procurement consideration.

Frequently Asked Questions
How does the 0.050-inch pitch of TFC-109-02-FM-D-A compare to standard 0.100-inch pitch terminal strips for compact PCB layouts?
At 0.050-inch pitch, TFC-109-02-FM-D-A occupies roughly half the connector body length of a 0.100-inch pitch 18-position strip, enabling denser signal routing in space-constrained PCBs. This is particularly valuable in portable medical devices, wearables, and handheld instruments where board real estate is limited to a few square centimeters.
What does the Tiger Eye contact geometry in TFC-109-02-FM-D-A provide for signal reliability in high-cycle applications?
The Tiger Eye dual-beam contact design creates 2 independent contact points per position, with each beam wiping the mating surface during insertion to clear oxidation and contamination. This redundant 2-wire contact mechanism maintains low contact resistance across hundreds of mating cycles in vibrating or thermally cycling environments typical of industrial sensor modules and portable instruments.
For which 18-pin board-to-board interconnect scenarios is TFC-109-02-FM-D-A the preferred choice over larger pitch alternatives?
TFC-109-02-FM-D-A suits embedded module stacking, daughter-card connections, and flex-to-board interfaces where 18 signal lines must be routed through a connector occupying less than 0.50 inches of PCB edge. Its 0.050-inch pitch and dual-row male contact layout cover USB hub boards, sensor daughtercards, and small SoC module-to-baseboard interconnects.
How does TFC-109-02-FM-D-A's cost-effective construction benefit high-volume IoT and consumer electronics procurement?
SAMTEC's cost-effective TFC series reduces per-position connector cost compared to precision or high-frequency alternatives while maintaining reliable Tiger Eye contact performance. For a design with 18 positions, using TFC-109-02-FM-D-A in volumes of 1000 or more pieces lowers BOM cost per unit versus higher-spec terminal strips without sacrificing the contact wipe and retention needed for standard signal interconnects.
