Key Features
- 46-position dual-row terminal strip on 0.050" (1.27 mm) pitch for high-density board-to-cable connections in minimal PCB area
- Tiger Eye contact technology provides superior mating reliability and consistent contact force across all 46 positions
- Keyed (K option) and low-profile (LM) design with tape-and-reel (TR) packaging for automated SMT assembly and mismating prevention
Applications
The TFC-123-02-LM-D-A-K-TR is suited for high-density flat flexible cable and ribbon cable terminations in compact electronics including medical devices, portable test instruments, and consumer computing peripherals. Its Tiger Eye contact design ensures reliable mating over multiple insertion cycles, reducing maintenance costs in field-serviceable equipment. The keyed low-profile format makes it practical for stacked PCB assemblies and devices installed in shallow enclosures where vertical clearance is limited.

Frequently Asked Questions
What pitch and position count does the TFC-123-02-LM-D-A-K-TR offer, and how does this benefit high-density designs?
The TFC-123-02-LM-D-A-K-TR features 46 positions on a fine 0.050" (1.27 mm) pitch in a dual-row layout. This fine pitch delivers up to 46 signal connections in roughly half the PCB footprint required by a standard 0.100" pitch connector of the same pin count, supporting compact board-to-cable routing in space-limited designs.
How does Tiger Eye contact technology in the TFC-123-02-LM-D-A-K-TR improve connector reliability?
Tiger Eye contacts use a dual-beam leaf spring design that maintains consistent contact force across all 46 positions throughout the connector's rated mating cycle life. This dual-wipe action improves resistance to vibration-induced contact resistance variation, making the TFC-123-02-LM-D-A-K-TR more reliable than single-beam alternatives in portable or mobile equipment exposed to shock and vibration.
How does the K (keyed) option protect the TFC-123-02-LM-D-A-K-TR during cable installation in a multi-connector panel?
The K option adds a mechanical polarisation key to the TFC-123-02-LM-D-A-K-TR housing that physically prevents inserting the mating cable connector in the wrong orientation. With 46 positions at 0.050" pitch, reversing insertion could short adjacent pins and damage both the connector and connected circuitry, so the keying is an essential safeguard for field technicians and automated assembly.
What cost advantage does the TFC Tiger Eye series offer compared to premium high-speed board-to-cable connectors at 0.050" pitch?
The TFC Tiger Eye series is engineered as a cost-effective alternative to premium high-speed cable connectors while maintaining the 0.050" pitch needed for high pin density. For designs where signal speeds do not require controlled impedance connectors rated above 1 GHz, the TFC-123-02-LM-D-A-K-TR provides a 46-position solution at significantly lower unit cost, improving BOM economics in medium-to-high volume production.
