Key Features
- 48-position, dual-row fine-pitch terminal strip at 0.050-inch (1.27 mm) pitch for high-density signal routing in compact PCB assemblies
- Tiger Eye contact design provides reliable wipe and normal force for consistent low-resistance connections across all 48 positions
- Cost-effective terminal strip format reduces interconnect BOM cost compared to higher-priced fine-pitch alternatives while maintaining SAMTEC quality
Applications
The TFC-124-02-FM-D-A is suited for high-density board-to-cable and board-to-board signal interconnects in embedded computing, test and measurement equipment, and communications hardware. Its 48-position, 0.050-inch pitch configuration allows twice the contact density of 0.100-inch pitch connectors in the same PCB footprint, benefiting compact module designs. The Tiger Eye contact style ensures reliable electrical contact through repeated mating cycles in production and field service environments.

Frequently Asked Questions
What pitch and position count does the TFC-124-02-FM-D-A offer, and how does that compare to standard 0.100-inch terminal strips?
The TFC-124-02-FM-D-A provides 48 positions at 0.050-inch (1.27 mm) pitch in a dual-row layout. This fine pitch delivers twice the contact density of standard 0.100-inch pitch strips in the same PCB length, enabling more signal lines to be routed through a given connector slot, which is critical in compact embedded systems and high-channel-count data acquisition boards.
What does the Tiger Eye contact design in the TFC-124-02-FM-D-A contribute to connector reliability?
SAMTEC's Tiger Eye contact geometry uses a dual-beam wiping action to clean the mating surface during insertion, maintaining low contact resistance across all 48 positions even after multiple mating cycles. The controlled normal force of the Tiger Eye design reduces insertion force compared to rigid-pin alternatives while ensuring reliable electrical contact over the product lifetime in demanding applications.
For a high-channel-count PCB design, when is the TFC-124-02-FM-D-A a cost-effective alternative to higher-priced fine-pitch connectors?
The TFC-124-02-FM-D-A is positioned as a cost-effective choice when a design requires 48 or more signal connections at 0.050-inch pitch but does not demand the extreme mating cycle life or environmental sealing of premium fine-pitch connectors. Applications such as backplane daughtercard interfaces, ribbon cable terminations in industrial instruments, and prototype test fixtures benefit from its lower cost per position without sacrificing SAMTEC's contact reliability standards.
