Key Features
- 40-position dual-row 1.27 mm pitch receptacle for high-density board-to-board mating in compact embedded systems
- Gold (15 µin) over nickel (50 µin) mating contact finish ensuring low contact resistance and long insertion life
- Integrated weld tab for superior mechanical retention on PCB, preventing connector movement under vibration or repeated mating cycles
Applications
The TFM-120-01-L-D-RE1-WT is designed for high-density board-to-board interconnects in embedded computing, single-board computers, and modular industrial control systems. The 1.27 mm pitch dual-row receptacle mates with corresponding TFM series headers to create reliable, compact signal and power interfaces. Its weld tab construction adds mechanical security in applications subject to vibration or repeated plug-and-unplug operations.

Frequently Asked Questions
What contact finish does the TFM-120-01-L-D-RE1-WT use and how does it affect connector reliability?
The TFM-120-01-L-D-RE1-WT features gold (15 µin) over nickel (50 µin) mating contact finish, which provides excellent corrosion resistance and stable contact resistance over many thousands of insertion cycles. This finish is preferred in applications requiring reliable signal integrity in environments with temperature cycling or humidity exposure.
How does the weld tab on the TFM-120-01-L-D-RE1-WT improve mechanical performance compared to standard SMT connectors?
The integrated weld tab solders directly to the PCB copper, adding shear and pull-out strength beyond what solder-only SMT leads provide. In applications with 5 g vibration or repeated mating cycles, the weld tab prevents the connector body from lifting off the board, maintaining the 1.27 mm pitch alignment critical for all 40 positions.
What is the factory lead time for TFM-120-01-L-D-RE1-WT and how quickly can it ship?
The SAMTEC TFM-120-01-L-D-RE1-WT has a factory lead time of 1 week, which is significantly shorter than most specialty connectors. SAMTEC typically ships from stock for standard configurations, enabling rapid prototyping and short production runs for designs requiring the 40-position 1.27 mm pitch dual-row receptacle.
