Frequently Asked Questions
What special contact technology does TFM-120-02-L-D-LC use and why does it matter for vibration applications?
TFM-120-02-L-D-LC uses SAMTEC's TIGER EYE contact technology combined with a split board lock (E.L.P.) mechanism. TIGER EYE contacts provide a wiping action on mating, ensuring reliable low-resistance connections even after repeated mating cycles or prolonged vibration exposure at frequencies up to hundreds of Hz, which is critical for automotive under-hood modules operating across -40°C to +125°C.
How does the 1.27 mm pitch of TFM-120-02-L-D-LC help in automotive PCB designs with limited board space?
The 1.27 mm pitch with 40 positions in a dual-row 2x20 layout enables high-density routing within a body length of approximately 1.125 inches, making it suitable for compact automotive PCBs where large connectors cannot be accommodated. Compared to 2.54 mm pitch connectors with equivalent pin count, TFM-120-02-L-D-LC occupies roughly half the board length, freeing space for other components.
Is TFM-120-02-L-D-LC compatible with standard lead-free reflow soldering for SMT assembly?
Yes, TFM-120-02-L-D-LC features tin (Sn) with nickel (Ni) barrier termination, which is compatible with lead-free reflow soldering at standard peak temperatures around 260°C. Its SMT footprint integrates into automated pick-and-place production lines, and the tube packaging supports both manual and automated loading for low-to-mid volume production runs.
For a motor controller board requiring 40 signals between stacked PCBs, how does TFM-120-02-L-D-LC compare to a single-row alternative?
A single-row 40-pin connector at 1.27 mm pitch would occupy approximately 50 mm of board edge, while the dual-row 2x20 TFM-120-02-L-D-LC achieves 40 contacts in a body length of about 1.125 inches (28.6 mm). The dual-row format saves roughly 21 mm of PCB edge space on a motor controller, which is significant in compact drive designs where board real estate is constrained.
