What are the key features of TFM-109-03-S-D-RA?
- 18 total positions in a dual-row right-angle layout at 0.050" (1.27 mm) pitch, enabling parallel signal routing in a narrow 9 mm connector length
- Tiger Eye beryllium copper spring contacts provide consistent low contact resistance and reliable signal integrity across hundreds of mating cycles
- Right-angle orientation accommodates board-edge interconnect designs where perpendicular mating keeps stack height under 10 mm
What is TFM-109-03-S-D-RA used for?
The TFM-109-03-S-D-RA serves compact embedded computing, industrial sensor modules, and test instrumentation designs requiring 18-channel board-to-board or board-to-flex connectivity at 0.050" pitch. Its right-angle dual-row layout is well-suited for PCB edge connectors in plug-in module systems where a vertical mating profile would exceed height clearance constraints. The high-reliability Tiger Eye contact design makes it a robust choice for applications with repeated plug-and-unplug maintenance cycles, such as modular field instruments and programmable logic controller (PLC) expansion cards.

Frequently Asked Questions
How compact is the TFM-109-03-S-D-RA connector footprint, and how many contacts does it provide?
The TFM-109-03-S-D-RA packs 18 contacts—9 per row—into a dual-row right-angle footprint spanning approximately 9 mm in length at a 0.050" (1.27 mm) pitch. This makes it one of the smaller Tiger Eye connectors in the TFM family, ideal for compact 18-signal interfaces such as SPI buses with chip-selects, sensor arrays, or small parallel data paths.
In what type of industrial or embedded designs does an 18-position right-angle connector like the TFM-109-03-S-D-RA offer the best fit?
An 18-position right-angle connector at 1.27 mm pitch is well-matched to modular PLC expansion cards, compact IMU sensor boards, and fieldbus interface modules where the I/O count is 16 to 18 signals and vertical height clearance is below 10 mm. The dual-row layout keeps the connector length under 12 mm, leaving room for decoupling capacitors and routing in tight PCB designs.
How does the TFM-109-03-S-D-RA compare to an IDC header solution for the same 18-position interface?
Unlike a standard 2.54 mm pitch IDC header, the TFM-109-03-S-D-RA uses a 0.050" (1.27 mm) pitch, reducing the connector footprint by roughly 50% in length for the same 18-pin count. The Tiger Eye contact system also offers lower insertion force and better resistance to micro-vibration compared to conventional stamped IDC contacts, making it more reliable in high-cycle or vibration-prone field equipment.
