Frequently Asked Questions
What pitch and row configuration does the SAMTEC TFM-121-12-S-D-A-P-TR use for SMT board-to-board interconnect?
The TFM-121-12-S-D-A-P-TR features a dual-row SMT configuration with 0.050-inch (1.27 mm) pitch, providing a high-density footprint for board-to-board signal routing. This layout accommodates many contact positions in a compact space, ideal for data-intensive multi-signal interconnects in industrial and defense electronics.
How does the Tiger Eye locking mechanism benefit designs operating across wide temperature ranges?
The Tiger Eye locking mechanism maintains contact integrity under continuous vibration and shock across an operating temperature range of -55°C to +125°C. This makes the TFM-121-12-S-D-A-P-TR suitable for defense avionics, ruggedized industrial controllers, and medical imaging equipment exposed to repeated mechanical stress and thermal cycling.
When should designers choose the TFM-121-12-S-D-A-P-TR over a standard non-locking terminal strip?
Designers should choose this connector when their application requires positive retention under shock or vibration, such as in avionics line-replaceable units or downhole tools operating up to +125°C. The polarization key also prevents miswiring across dual-row signal buses with 50 or more pins, reducing costly PCB rework in high-reliability assemblies.
