Applications
The TFC-109-02-LM-D-A is designed for high-density signal interconnects in compact embedded systems, FPGA prototyping boards, and test fixture assemblies where 0.050 inch pitch minimizes PCB real estate. Its 18-position dual-row layout is ideal for parallel data buses, multi-channel sensor interfaces, and backplane signal distribution. The Tiger Eye contact mechanism ensures reliable mating force across repeated insertion cycles in development and production test environments.

Frequently Asked Questions
What pitch and position count does TFC-109-02-LM-D-A provide for high-density board connections?
The TFC-109-02-LM-D-A provides 18 positions in a dual-row (9 contacts per row) layout with a 0.050 inch (1.27 mm) pitch. This fine pitch enables nearly double the contact density compared to standard 0.100 inch pitch connectors, making it ideal for compact embedded computing and FPGA boards.
How does the Tiger Eye contact mechanism in TFC-109-02-LM-D-A improve connection reliability?
The Tiger Eye contact design uses a dual-beam spring contact that grips the mating pin from 2 sides, providing consistent contact force and reliable electrical continuity across all 18 positions. This mechanism maintains stable low-resistance connections even under vibration or thermal cycling conditions typical in industrial and test applications.
What are the key differences between TFC-109-02-LM-D-A and standard 0.100 inch pitch terminal strips?
TFC-109-02-LM-D-A uses a 0.050 inch (1.27 mm) pitch, which is half the spacing of standard 2.54 mm pitch strips, allowing 18 contacts in roughly the same space as 9 pins on a standard strip. This makes it the preferred choice when PCB area is limited and routing more than 10 signals in a compact dual-row format is required.
In which prototype or production test environments is TFC-109-02-LM-D-A typically deployed?
TFC-109-02-LM-D-A is commonly deployed in FPGA development boards, high-density test fixture headers, and evaluation modules where 18 pins at 1.27 mm pitch connect daughtercards to carrier boards. Its low-profile LM surface mount termination and cost-effective Tiger Eye contacts support rapid prototyping and volume production testing with a 0.050 inch pitch footprint.
