Key Features
- 52-position dual-row 0.050" (1.27 mm) pitch layout delivering high connection density equivalent to 26 positions per row in a compact SMT footprint
- Tiger Eye contact design providing a wiping mating action that clears surface oxides, ensuring reliable low-resistance connections across repeated mating cycles
- Cost-effective TFC series construction offering a budget-friendly alternative to premium connectors without sacrificing 0.050" pitch mechanical precision
Applications
The TFC-126-02-F-D-A is designed for compact board-to-board and module interconnect applications in communications equipment, embedded computing platforms, and portable instrumentation. Its 52-position dual-row configuration at 0.050" pitch allows designers to route 52 signals through a footprint that a standard 0.100" connector would need twice the space to accommodate. The cost-effective Tiger Eye contact system supports moderate mating cycles, making it ideal for production test fixtures and modular system architectures with periodic daughtercard replacement.

Frequently Asked Questions
How many connections does the TFC-126-02-F-D-A provide and what pitch does it use?
The TFC-126-02-F-D-A provides 52 total positions arranged in a dual-row layout at a 0.050" (1.27 mm) pitch, giving 26 positions per row. This fine pitch allows the connector to fit twice as many signals in the same board length compared to a 0.100" pitch connector, which is a significant advantage in space-constrained module and daughtercard designs.
What makes the Tiger Eye contact technology on TFC-126-02-F-D-A well-suited for SMT board-to-board mating?
The Tiger Eye contact geometry on the TFC-126-02-F-D-A creates a controlled wiping engagement of approximately 0.3 mm during mating, which mechanically scrubs contact surfaces to remove oxide layers and particulate contamination. This ensures consistent contact resistance below 30 milliohms per contact even after repeated mating cycles, which is important in modular systems where daughtercards are swapped during servicing or reconfiguration.
When is TFC-126-02-F-D-A a cost-effective alternative to premium 0.050" board-to-board connectors?
TFC-126-02-F-D-A is a practical lower-cost option when the design requires fewer than 500 mating cycles and signal frequencies below 1 GHz, where the cost-effective Tiger Eye construction meets performance requirements without the premium pricing of high-speed or high-cycle connectors. For applications such as embedded module test fixtures or low-frequency data acquisition daughtercards, the TFC series provides the necessary 52-position 0.050" pitch connectivity at reduced BOM cost.
