Key Features
- 8-position dual-row terminal strip with 0.050" (1.27 mm) pitch for compact signal interconnect applications
- Low-profile LM contact style minimizes board height while maintaining reliable Tiger Eye mating performance
- Kinked (K) through-hole tail anchors connector to PCB during soldering, preventing 4-position-per-row misalignment
- Cost-effective Tiger Eye terminal strip design for budget-sensitive board-to-board interface requirements
Applications
The TFC-104-02-LM-D-A-K is suited for compact board-to-board signal interfaces in embedded microcontroller boards, sensor modules, and industrial I/O panels where only 8 positions at 0.050" pitch are needed. Its low-profile LM contact style reduces stack height compared to standard terminal strip variants, enabling closer board-to-board spacing in stacked module designs. Kinked tails ensure reliable mechanical hold during wave or hand solder assembly.

Frequently Asked Questions
What position count and pitch does the TFC-104-02-LM-D-A-K offer for board signal connections?
The TFC-104-02-LM-D-A-K is an 8-position dual-row terminal strip with 0.050" (1.27 mm) pitch, giving 4 positions per row. This compact footprint is well suited for small embedded modules and sensor boards where signal channel count is limited but space-efficient connector design is essential.
What does the LM suffix mean on the TFC-104-02-LM-D-A-K and how does it affect PCB stack height?
The LM suffix on the TFC-104-02-LM-D-A-K designates a low-profile mating contact style, which reduces the above-board height of the 8-position connector compared to standard contact variants. This is particularly beneficial in stacked PCB designs where minimizing the gap between boards at 0.050" pitch is a layout requirement.
For which low-channel-count applications is the TFC-104-02-LM-D-A-K a better fit than higher-position variants?
The TFC-104-02-LM-D-A-K with only 8 positions at 0.050" pitch is ideal for sensor module interconnects, small microcontroller daughterboards, and I/O expander boards where fewer than 10 signal lines are needed. Using a lower-position-count connector avoids unnecessary PCB area consumption and reduces per-unit connector cost compared to 20- or 30-position variants.
Why are kinked tails important for the TFC-104-02-LM-D-A-K during PCB soldering?
The kinked through-hole tail (K suffix) on the TFC-104-02-LM-D-A-K locks the 8-position connector in place on the PCB before and during soldering, preventing any movement across the 1.27 mm pitch row. This mechanical pre-alignment reduces the risk of off-center solder joints and ensures consistent contact registration with the mating connector.
