Key Features
- 40-position dual-row 0.050 inch pitch right-angle receptacle for high-density board-to-board signal interconnects
- Shrouded housing provides polarization and protection against mis-mating in compact PCB assemblies
- Matte tin over nickel contact finish ensures reliable solderability and corrosion resistance over extended service life
- Right-angle (RA) termination allows horizontal connector exit suited for edge-mount and low-profile enclosure designs
- Pb-free, RoHS-compliant construction for compliance with modern environmental regulations
Applications
The SAMTEC TFML-120-01-L-D-RA right-angle receptacle is used in embedded computing modules, FPGAs, and DSP boards where high-density 0.050 inch pitch board-to-board mating is needed in a horizontal cable or board exit configuration. Its 40-position dual-row shrouded design prevents incorrect insertion, making it a reliable choice in test equipment, communications cards, and industrial I/O expansion boards. The right-angle body also reduces connector height above the PCB plane, enabling system designs with tight vertical clearance constraints.

Frequently Asked Questions
How many positions and what pitch does TFML-120-01-L-D-RA provide?
The TFML-120-01-L-D-RA provides 40 total positions in a dual-row configuration on a 0.050 inch (1.27 mm) contact pitch. This high-density 20×2 layout fits within a 1.125 inch body length, making it one of the most space-efficient options for board-to-board signal interconnects on 50-mil grid PCBs.
Why choose a right-angle orientation for TFML-120-01-L-D-RA in a PCB assembly?
The right-angle (RA) termination routes the mating direction parallel to the PCB surface, which is critical in enclosures where the connector must exit through a panel edge or where a vertical connector would exceed the allowed 0.29 inch height above the board. This orientation is standard in rack-mounted communications cards and compact embedded computing boards with less than 15 mm total assembly height.
What contact plating is used on TFML-120-01-L-D-RA and how does it affect soldering?
The TFML-120-01-L-D-RA uses a matte tin (Sn) over nickel (Ni) barrier contact finish. The nickel underplate prevents tin diffusion and improves corrosion resistance, while the matte tin surface is fully compatible with lead-free SAC305 reflow solder processes operating at peak temperatures up to 260 °C.
Which SAMTEC plug or header series mates directly with TFML-120-01-L-D-RA?
The TFML-120-01-L-D-RA is designed to mate with SAMTEC FTML and TMML series 0.050 inch pitch dual-row plug connectors. A 40-position mating plug provides 40 reliable signal paths with contact normal forces typically rated at 100 gf per contact, ensuring stable mating in vibration-prone industrial and computing environments.
