What are the key features of TFM-109-02-S-D-RA?
- 18 total pins (9 per row, dual-row) at 0.050-inch (1.27 mm) pitch provide high-density right-angle cable-to-board connections in a compact footprint
- Tiger Eye contact system ensures high-reliability mating retention and consistent low contact resistance across thousands of insertion cycles
- Right-angle (RA) orientation routes all 18 pins horizontally from the board edge, minimising above-board connector height
- Rated for operating temperatures of -55 °C to +125 °C, suiting military, aerospace, and rugged industrial applications
What is TFM-109-02-S-D-RA used for?
The TFM-109-02-S-D-RA is designed for compact right-angle cable-to-board and daughter-card interconnect applications in military electronics, industrial instrumentation, and communications systems where 18 reliable signal connections are needed at a fine 0.050-inch pitch. Its right-angle orientation routes the mating interface perpendicular to the PCB surface, simplifying cable harness assembly and enabling horizontal signal exit paths in enclosed chassis designs. Tiger Eye contact technology ensures consistent mating force and stable electrical performance throughout the full service life of the assembly.

Frequently Asked Questions
How many pins does the TFM-109-02-S-D-RA offer, and what pitch do the contacts use?
The TFM-109-02-S-D-RA provides 18 pins arranged in 2 rows of 9 contacts each at a 0.050-inch (1.27 mm) centre-to-centre pitch. This dual-row right-angle configuration is ideal for compact cable-to-board assemblies where a moderate signal count must exit the PCB edge horizontally, keeping the connector footprint small while maintaining a high-reliability mating interface.
In which demanding applications does the Tiger Eye contact system of the TFM-109-02-S-D-RA provide the most value?
The Tiger Eye contacts in the TFM-109-02-S-D-RA are engineered for military avionics, aerospace sub-systems, and rugged industrial instrumentation that require reliable 18-pin interconnects sustained across thousands of mating cycles. The connector operates over a temperature range of -55 °C to +125 °C, maintaining consistent contact resistance even in environments subject to thermal shock, vibration, and humidity extremes.
How does the right-angle (RA) orientation of the TFM-109-02-S-D-RA benefit cable routing in enclosed chassis assemblies?
With right-angle termination, the TFM-109-02-S-D-RA aligns all 18 pins horizontally so cable harnesses exit parallel to the PCB surface rather than rising above it. This reduces the clearance needed between the board and adjacent chassis walls, allows multiple connectors to share the same board edge in a compact enclosure, and simplifies cable management in rack-mount and embedded systems where vertical space is limited.
Why choose the dual-row TFM-109-02-S-D-RA over a single-row 18-pin right-angle alternative at the same pitch?
The dual-row TFM-109-02-S-D-RA occupies roughly half the board-edge length of a single-row 18-pin connector at the same 0.050-inch pitch, freeing board-edge space for additional connectors or components. The two-row arrangement also distributes mating and extraction forces across 9 contacts per row, reducing the lever-arm stress on individual solder joints and improving long-term mechanical reliability in applications subject to cable strain or repeated mating cycles.
