What are the key features of TFC-143-02-LM-D-A?
- 86-position dual-row configuration at 0.050" (1.27 mm) pitch packing 43 contact pairs into a minimal PCB footprint
- Tiger Eye contact technology delivers reliable mating performance at reduced cost compared to machined contact alternatives
- LM-style low-profile termination suits space-constrained board layouts where standard connector heights would cause clearance issues
What is TFC-143-02-LM-D-A used for?
The TFC-143-02-LM-D-A is engineered for high-density board-to-board and daughter card interconnections in telecommunications systems, server blades, and industrial control hardware. Its 86-position dual-row layout at 0.050" pitch enables routing of 43 signal pairs across a short PCB edge, reducing connector count and saving board area. The low-profile LM termination style allows this strip to fit in enclosures with tight vertical clearances between stacked PCBs.

Frequently Asked Questions
How many contact pairs does TFC-143-02-LM-D-A provide and what pitch spacing does it use?
The TFC-143-02-LM-D-A provides 86 positions in a dual-row layout, yielding 43 contact pairs at a 0.050" (1.27 mm) pitch. This high density is twice that of standard 0.100" pitch connectors, making it ideal for telecom and computing applications where maximizing signal count per unit PCB edge length is a priority.
What distinguishes the LM termination style of TFC-143-02-LM-D-A from standard FM or F termination variants?
The LM termination style on TFC-143-02-LM-D-A refers to a low-profile solder tail geometry that reduces the standoff height above the PCB surface compared to standard full-mount (FM) or formed (F) variants. This lower profile, typically under 0.050 inches of additional height, is essential in stacked PCB designs or low-profile enclosures where vertical clearance between boards is limited to a few millimeters.
For a modular server backplane needing 86 signal connections, how does TFC-143-02-LM-D-A compare to using multiple smaller connectors?
Using a single TFC-143-02-LM-D-A with 86 positions at 0.050" pitch consolidates what would otherwise require multiple smaller connectors, reducing total connector count, assembly steps, and potential mating failure points. A single 86-position strip occupies roughly 2.15 inches of board edge length at 0.050" pitch row spacing, compared to multiple connectors that would consume more total PCB area and require more assembly labor.
