What are the key features of TFC-125-02-LM-D-A-K?
- 50-position dual-row 0.050" (1.27 mm) pitch configuration supports dense signal routing for mezzanine and backplane interconnects
- Tiger Eye contact design delivers higher normal force than standard stamped contacts, improving reliability over extended mating cycles
- Low-profile right-angle through-hole mounting (LM) suits applications requiring horizontal cable routing or board edge connector access
What is TFC-125-02-LM-D-A-K used for?
The TFC-125-02-LM-D-A-K is ideal for horizontal board-to-board stacking and panel-edge signal routing in compact embedded systems, telecommunications equipment, and industrial automation controllers requiring 50 dual-row connections at 1.27 mm pitch. Its right-angle low-profile mount orientation positions the mating interface parallel to the PCB surface, facilitating access from the board edge in chassis-mounted applications. Tiger Eye contacts paired with matching SFM-series sockets provide a low-resistance, high-cycle interconnect solution across 50-position interfaces.

Frequently Asked Questions
What does the LM suffix indicate for TFC-125-02-LM-D-A-K, and how does it affect PCB layout?
The LM suffix designates a low-profile right-angle through-hole mount configuration, meaning the mating interface of the TFC-125-02-LM-D-A-K is oriented parallel and close to the PCB surface. This reduces the total stack height compared to standard right-angle variants and allows 50-position connectors to be accessed from the board edge in enclosed or chassis-mounted designs where vertical clearance is below 8 mm.
How does the 50-position TFC-125-02-LM-D-A-K compare in footprint to a 2.00 mm pitch connector of equivalent position count?
At 0.050" (1.27 mm) pitch, the TFC-125-02-LM-D-A-K places 50 dual-row positions in approximately 1.25 inches of board length, while a 2.00 mm pitch connector for 50 positions would span roughly 2.00 inches. This approximately 38% reduction in connector length is critical for compact PCBs in network switches, server blades, and portable instruments where every millimeter of board space affects system density.
Which SAMTEC socket strips mate with TFC-125-02-LM-D-A-K, and what contact performance can be expected?
The TFC-125-02-LM-D-A-K mates with SAMTEC SFM and TSM series dual-row socket strips designed for 0.050" (1.27 mm) pitch. These mating sockets feature Tiger Eye or standard contacts and are specified for contact resistance below 20 mΩ and current ratings up to 1 A per pin at 25°C. The 50-position matched pair delivers consistent signal integrity across the full interface over up to 500 mating cycles in standard operating conditions.
