TFC-129-02-LM-D-A SAMTEC Connector (Other) In Stock

What are the key features of TFC-129-02-LM-D-A?

• 58-position dual-row terminal strip at 0.050" (1.27 mm) pitch supports high signal-count board-to-board connections in a compact SMT footprint
• Long machined (LM) contacts extend approximately 0.5 mm deeper into mating headers, improving alignment and retention in vibration-sensitive assemblies
• Tiger Eye cost-effective design offers precision machined contact quality at a reduced per-pin cost compared to premium Samtec series
• Gold-plated mating interface maintains low contact resistance below 30 mΩ across 100 or more mating cycles for reliable signal integrity

What is TFC-129-02-LM-D-A used for?

The TFC-129-02-LM-D-A is suited for embedded processor daughter cards, FPGA I/O expansion boards, and compact industrial controllers where 58 signal lines must pass between stacked PCBs at a 1.27 mm pitch. The long machined contact variant provides extra mechanical engagement depth for applications with light shock or vibration, such as portable instrumentation and vehicular electronics modules. Its SMT footprint is compatible with automated reflow assembly, making it cost-efficient for medium-to-high volume production of communications and computing hardware.
