Key Features
- 56-position dual-row Tiger Eye terminal strip on 0.050" (1.27 mm) pitch for high-density interconnects
- Locking (-K) feature provides mechanical retention preventing accidental disconnection under vibration
- Cost-effective design suitable for high-volume production without sacrificing contact reliability
Applications
The TFC-128-02-LM-D-A-K is designed for high-density board-to-board signal routing in applications such as networking equipment, data storage systems, and industrial control platforms. Its 56-position dual-row configuration on a 0.050" pitch enables significant signal concentration in constrained board layouts. The locking retention feature makes it especially reliable in environments subject to mechanical vibration or frequent connection cycles.

Frequently Asked Questions
How many signal positions does the TFC-128-02-LM-D-A-K provide, and what is the contact pitch?
The TFC-128-02-LM-D-A-K provides 56 positions arranged in a dual-row layout, with 28 contacts per row on a 0.050" (1.27 mm) pitch. This configuration allows high-density signal routing on PCBs where space efficiency is critical.
What is the Tiger Eye contact system in the TFC-128-02-LM-D-A-K and why does it matter?
The Tiger Eye contact system is Samtec's proprietary low-cost stamped contact technology designed for reliable mating with standard 0.050" pin headers. It maintains consistent normal force across all 56 positions, supporting stable signal transmission even in vibration-prone environments.
When should engineers select the TFC-128-02-LM-D-A-K over a non-locking version?
The -K locking suffix should be selected when the application experiences mechanical vibration, shock, or repeated mating cycles that risk accidental unmating. Applications such as industrial control panels, ruggedized communication boards, and test fixtures benefit from the additional mechanical retention provided by the locking feature on this 56-position connector.
