Key Features
- 44-position dual-row layout on a 0.050-inch (1.27 mm) pitch enables very high contact density per unit of board length
- Tiger Eye low-insertion-force contact design reduces mating force while maintaining reliable electrical connection across multiple mating cycles
- Cost-effective terminal strip construction makes it suitable for high-volume production without sacrificing signal integrity
Applications
The TFC-122-02-LM-D-A-K is commonly used in high-density signal distribution applications such as backplane connections, test fixtures, and embedded computing modules where 44 signal lines must be routed in a compact 0.050-inch pitch footprint. Its dual-row design and low-mating-force contacts make it suitable for board-to-board interconnects in instrumentation, industrial automation, and telecommunications equipment.

Frequently Asked Questions
How many positions and rows does the TFC-122-02-LM-D-A-K provide, and what is its contact pitch?
The TFC-122-02-LM-D-A-K offers 44 positions arranged in a dual-row configuration with a 0.050-inch (1.27 mm) contact pitch. This high-density layout is well suited for applications that require routing many signal lines within a constrained PCB area.
What type of contact mechanism does the Tiger Eye series use, and how does it benefit assembly?
The Tiger Eye series uses a low-insertion-force contact design that reduces the mechanical force required during mating, minimizing risk of PCB flex or connector damage during assembly. This feature is especially valuable in automated assembly lines handling boards with 44 or more signal contacts at 0.050-inch pitch.
Which application environments benefit most from the TFC-122-02-LM-D-A-K terminal strip?
This terminal strip performs well in test and measurement fixtures, backplane interconnects, and industrial embedded systems that need at least 44 signal channels routed through a dual-row, 1.27 mm pitch connector. Its cost-effective design supports high-volume manufacturing while maintaining signal integrity across all 44 contact positions.
How does the dual-row, 0.050-inch pitch of TFC-122-02-LM-D-A-K compare to single-row alternatives?
The dual-row layout at 0.050-inch pitch achieves twice the contact density of a single-row header of the same length, allowing 44 contacts in roughly the board footprint that a single-row 22-contact strip would occupy. This halves the connector length and reduces PCB routing distance between paired signal lines.
