What are the key features of TFM-116-01-S-D-RA?
- Tiger Eye contact technology provides superior normal force and mating reliability over thousands of insertion cycles
- 32-position dual-row 0.050" (1.27 mm) pitch right-angle configuration enables vertical-to-horizontal board interconnects
- Gold over nickel contact finish delivers low contact resistance and excellent corrosion protection for critical signal paths
- Phosphor bronze contact material maintains optimal spring force across the full operating temperature range
- Right-angle termination (RA) allows daughter card connection parallel to the motherboard plane in space-constrained enclosures
What is TFM-116-01-S-D-RA used for?
The TFM-116-01-S-D-RA is used in high-reliability board-to-board right-angle connections for telecommunications line cards, military electronics, and test equipment where the 0.050" pitch accommodates high signal density in restricted vertical board clearance. The Tiger Eye contact geometry is preferred in applications requiring repeated mating cycles, such as removable daughter cards or field-replaceable modules. Gold plating suits RF and low-level signal applications where contact resistance must be minimized.

Frequently Asked Questions
What does the Tiger Eye contact technology in the TFM-116-01-S-D-RA offer compared to standard socket contacts?
Tiger Eye contacts in the TFM-116-01-S-D-RA use a specially formed stamping that generates higher and more consistent normal force against the mating pin compared to standard bifurcated contacts. This results in lower and more stable contact resistance across thousands of mating cycles. The geometry also provides a wiping action during insertion that cleans the mating surface, making it advantageous in applications with contamination risk or frequent board swapping.
For a telecom line card design, how does the right-angle (RA) orientation of TFM-116-01-S-D-RA simplify board stacking?
The right-angle orientation of the TFM-116-01-S-D-RA allows a daughter card to be plugged horizontally into a connector mounted perpendicular on a backplane, without requiring the daughter card to extend beyond the backplane edge. This enables 1U rack card designs where the daughter card stands upright and the connector engages from the side at the 0.050" pitch spacing. The 32-position dual-row configuration routes 32 signals in a single right-angle connector zone that would otherwise require two vertical connectors.
How does the 0.050" pitch of TFM-116-01-S-D-RA affect the trace routing density on a 6-layer PCB?
At 0.050" (1.27 mm) pitch with dual rows, the TFM-116-01-S-D-RA contact pads are spaced 1.27 mm center-to-center within each row. On a 6-layer PCB, this typically allows 1 trace per gap using 8 mil traces and 7 mil clearance, requiring an inner-layer via breakout strategy for all 32 signals. Compared to 0.100" pitch connectors, the 0.050" pitch halves the escape zone length but demands tighter PCB design rules and is better suited for controlled-impedance HDI boards.
When is TFM-116-01-S-D-RA preferred over the SFM-series socket strips for high-reliability interconnects?
The TFM-116-01-S-D-RA is preferred over SFM-series sockets when right-angle board orientation is required and the Tiger Eye contact's higher normal force is needed for demanding mating cycle counts exceeding 500 insertions. The gold over nickel finish on TFM parts specifically suits low-level signal connections below 100 mV where base metal contamination could introduce noise, whereas SFM-series parts with standard tin finish are more suitable for power pins and digital signals above 1 V logic thresholds.
