What are the key features of TFC-122-02-LM-D-A?
- 44-position dual-row layout on 0.050 inch pitch enables high-density signal interconnects in half the PCB footprint of standard 0.100 inch pitch connectors
- Tiger Eye contact geometry provides consistent spring-force mating retention and reliable electrical contact across more than 1000 insertion cycles
- Cost-effective terminal strip design reduces connector BOM cost while maintaining SAMTEC's quality standards for signal integrity in compact embedded systems
What is TFC-122-02-LM-D-A used for?
The TFC-122-02-LM-D-A is well-suited for compact embedded computing modules, FPGA mezzanine cards, and high-density PCB interconnect applications where 44 signals must be routed across a 0.050 inch pitch dual-row interface in a minimal footprint. Its Tiger Eye contact design supports reliable board-to-board signal connections in medical instrumentation, industrial sensors, and communications equipment requiring repeated mating cycles without contact degradation. The cost-effective construction makes it appropriate for high-volume production designs where connector cost per position is a key BOM consideration.

Frequently Asked Questions
What contact pitch and position count does the TFC-122-02-LM-D-A provide for PCB signal routing?
The TFC-122-02-LM-D-A offers 44 positions in a dual-row configuration on a 0.050 inch (1.27 mm) pitch. This fine pitch doubles the connection density compared to standard 0.100 inch pitch connectors, enabling 44-signal routing in roughly the same PCB area that a 0.100 inch pitch connector would need for only 22 positions.
How does SAMTEC's Tiger Eye contact geometry in the TFC-122-02-LM-D-A improve mating reliability?
SAMTEC's Tiger Eye contact design uses a dual-beam spring contact with a shaped tip that wipes the mating surface during insertion, removing thin oxide layers and ensuring a low and consistent contact resistance below 50 mΩ across multiple mating cycles. This wiping action maintains reliable signal integrity in the 44-position interface even after more than 1000 insertion and extraction cycles in production test and field-maintenance environments.
When is the TFC-122-02-LM-D-A a more economical connector choice than a SAMTEC high-speed or RF-rated alternative?
The TFC-122-02-LM-D-A is the preferred choice when the application requires reliable low-frequency signal connections below 500 MHz across 44 positions at the lowest possible cost per position, and high-speed impedance control or RF performance is not needed. Compared to SAMTEC high-speed connector families rated above 10 Gbps, the TFC-122-02-LM-D-A reduces cost by 30% to 50% per position, making it suitable for digital I/O, power, and general-purpose signal busses in cost-sensitive embedded and industrial designs.
