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.

Frequently Asked Questions
How much connector density does TFC-129-02-LM-D-A provide for a mezzanine PCB?
TFC-129-02-LM-D-A is a 58-position dual-row terminal strip using a 0.050 inch pitch, which supports dense board-to-board signal routing in compact SMT assemblies.
Which assembly fit details should be checked before approving this part for production?
Designers should verify the 1.27 mm pitch footprint, dual-row layout, and board alignment requirements because the long machined contacts must match the mating connector and PCB stack geometry.
What procurement risk is reduced by ordering the exact TFC-129-02-LM-D-A configuration?
Using the exact 58-position Samtec configuration helps avoid mismatches in contact length, row layout, or alignment features that could delay production lots or require PCB rework.
