What are the key features of TFM-109-02-SM-D-RA?
- 18-position dual-row layout on 0.050 inch (1.27 mm) pitch enables high signal density in a compact SMD right-angle footprint
- Tiger Eye contact system provides consistent low contact resistance and reliable mating performance over extended cycle life
- Right-angle (-RA) termination allows board-edge signal routing, reducing the need for additional cabling in tight enclosures
What is TFM-109-02-SM-D-RA used for?
The TFM-109-02-SM-D-RA is suited for board-edge and mezzanine interconnect applications in telecommunications equipment, embedded computing modules, and industrial controllers where space is constrained. Its 18-position dual-row layout routes 18 signals across a 1.27 mm pitch footprint, making it effective in compact data acquisition and signal routing boards. The right-angle SMD termination also simplifies panel-edge access in enclosed instruments and handheld devices.

Frequently Asked Questions
How many contacts does the TFM-109-02-SM-D-RA provide and what is its row configuration?
The TFM-109-02-SM-D-RA provides 18 total contacts arranged in a dual-row configuration on a 0.050 inch (1.27 mm) pitch, with 9 contacts per row. This compact layout allows routing of 18 signals through a minimal PCB footprint, making it ideal for dense embedded system interconnects.
What does the right-angle (-RA) orientation offer for PCB layout flexibility?
The right-angle termination means the mating direction runs parallel to the PCB surface rather than perpendicular. This allows the connector to exit from the board edge, simplifying cable routing in enclosed enclosures or panel-mount applications. Combined with the 0.050 inch pitch, the RA orientation saves at least 4 mm of vertical board height compared to vertical SMD alternatives.
Is the TFM-109-02-SM-D-RA compatible with standard reflow soldering processes?
Yes, the surface-mount (SM) termination style is designed for reflow soldering. SAMTEC TFM series connectors typically withstand peak reflow temperatures up to 260°C, compatible with lead-free SAC305 solder alloys. This makes the part suitable for fully automated SMT assembly lines without manual soldering intervention.
When should an engineer choose TFM-109-02-SM-D-RA over a through-hole right-angle connector?
The SMD version eliminates the need for drilled through-holes, freeing up routing layers on multilayer PCBs with 4 or more layers. It also reduces board thickness constraints since no hole barrel protrudes below the board. For designs where PCB thickness is 1.6 mm or less and signal count is 18 pins, the SMD right-angle TFM variant reduces manufacturing steps and lowers assembly cost per unit.
