Key Features
- Gold-over-nickel contact finish on mating surfaces ensures reliable low-resistance connections rated for repeated mating cycles
- Split board lock (LC) feature mechanically secures the connector to the PCB, preventing accidental unmating under vibration
- Tape-and-reel (TR) packaging enables automated pick-and-place SMT assembly for high-volume production runs
Applications
The TFM-120-02-S-D-LC-P-TR is used in high-density board-to-board and mezzanine interconnect applications where reliable signal integrity and mechanical retention are critical. Its compact .050" pitch dual-row format and split board lock make it ideal for portable instruments, industrial control modules, and communications equipment where vibration resistance and space savings are both required.

Frequently Asked Questions
What contact finish does the TFM-120-02-S-D-LC-P-TR use and what mating cycles does it support?
The TFM-120-02-S-D-LC-P-TR uses gold-over-nickel on mating contacts and tin with a nickel barrier on termination contacts. Gold-over-nickel typically supports 100 or more mating cycles, providing stable contact resistance below 20 mΩ for reliable signal transmission in high-cycle connector applications such as test fixtures or field-replaceable modules.
How does the split board lock on the TFM-120-02-S-D-LC-P-TR improve mechanical reliability?
The split board lock (LC suffix) feature uses two mechanical tabs that press-fit into PCB holes, securing the connector body so it withstands lateral forces and vibration without unsoldering. This is especially valuable in automotive or industrial designs subject to 5 G or higher mechanical shock, keeping the 40-pin dual-row interface mechanically stable.
For a compact mezzanine PCB stack, how much board area does the TFM-120-02-S-D-LC-P-TR occupy?
The TFM-120-02-S-D-LC-P-TR body measures 1.125 inches long by 0.225 inches wide and 0.22 inches deep, giving it a footprint of roughly 1.125 x 0.225 inches (28.6 x 5.7 mm). This compact footprint makes it well-suited for mezzanine and daughter-card designs where PCB real estate is at a premium and 40 signals must be routed at .050" pitch.
