Key Features
- 22-position dual-row right-angle (RA) configuration at 0.050" (1.27 mm) pitch enabling perpendicular board-to-board connections in tight enclosures
- Gold-over-nickel mating contacts on phosphor bronze springs providing low contact resistance and high durability across hundreds of mating cycles
- Tiger Eye contact design offering superior wiping action and contact reliability compared to standard stamped contacts in high-vibration environments
Applications
The TFM-111-01-L-D-RA is used in right-angle board-to-board and mezzanine interconnect applications within compact multi-board assemblies, such as embedded computing modules, test and measurement instruments, and RF front-end boards. Its 0.050" pitch 22-position right-angle layout allows a daughtercard to connect perpendicularly to a motherboard where vertical stacking height is constrained. The Tiger Eye contact mechanism and gold-over-nickel finish make this connector suitable for high-reliability industrial and defense electronics requiring long service life.

Frequently Asked Questions
What contact finish does the TFM-111-01-L-D-RA use, and why does it matter for connector reliability?
The TFM-111-01-L-D-RA uses gold-over-nickel on the mating contact surfaces and tin with a nickel barrier on the termination tails. Gold plating on phosphor bronze contacts maintains contact resistance below 20 milliohms through hundreds of mating cycles and prevents oxidation in humid or corrosive environments, making it suitable for high-reliability military, aerospace, and industrial electronic systems.
How does the right-angle (RA) termination of the TFM-111-01-L-D-RA help in compact multi-board assemblies?
The right-angle termination allows the TFM-111-01-L-D-RA to connect two PCBs oriented at 90 degrees to each other, reducing the total assembly height compared to a vertical stacking configuration. For a 22-position dual-row 0.050" pitch connector, this right-angle layout fits within a 0.675 inch body length, enabling use in narrow chassis where a perpendicular daughtercard must plug into a horizontal motherboard with minimal clearance.
What is the Tiger Eye contact design in the TFM-111-01-L-D-RA, and how does it improve mating performance?
The SAMTEC Tiger Eye contact is a precision-machined turned-pin socket with a 4-finger beryllium copper or phosphor bronze spring structure that provides a wiping action during insertion. This wipe removes surface oxides at the mating interface, ensuring consistent contact resistance below 20 milliohms even after 500 mating cycles, outperforming stamped sheet-metal contacts which can develop fretting corrosion after 100 to 200 insertions in vibrating environments.
For a PCB with 22 control signals routed at 0.050" pitch, why choose the TFM-111-01-L-D-RA over a standard 0.100" right-angle header?
The TFM-111-01-L-D-RA fits 22 positions in a body length of 0.675 inch at 0.050" pitch, compared to approximately 1.1 inches required for the same position count at 0.100" pitch, saving over 0.4 inch of PCB edge space. For small form-factor boards under 3 inches wide, this difference allows an additional connector or component to be placed along the edge, and the gold-over-nickel contacts provide higher reliability than standard tin contacts used on most 0.100" headers.
