Key Features
- 92-position dual-row terminal strip on 0.050" (1.27 mm) pitch for ultra-high-density board-to-board signal routing
- Locking (-K) retention mechanism prevents accidental unmating in vibration-prone or high-cycle environments
- Tiger Eye cost-effective stamped contact design reduces per-pin cost in high-volume production scenarios
Applications
The TFC-146-02-LM-D-A-K is engineered for high-pin-count board-to-board interconnection in applications such as FPGA evaluation boards, high-speed backplanes, and complex data acquisition systems requiring 92 signals in a compact 0.050" pitch footprint. Its locking feature provides mechanical security in systems subject to shock, vibration, or repeated connection cycling. The cost-effective Tiger Eye contact technology makes it an economical choice for large-scale production without compromising interconnect reliability.

Frequently Asked Questions
How many signal pins does the TFC-146-02-LM-D-A-K provide and how are they distributed across rows?
The TFC-146-02-LM-D-A-K features 92 positions arranged in 2 rows of 46 contacts each, on a 0.050" (1.27 mm) pitch. This dual-row arrangement maximizes signal density per unit length, making it ideal for high-pin-count board-to-board connections in compact PCB designs.
Why is the locking feature (-K) important for the TFC-146-02-LM-D-A-K in demanding environments?
The -K locking suffix adds mechanical retention to the mated connector pair, preventing accidental disconnection under vibration, shock, or mechanical stress. For a 92-position connector carrying critical signals, unintended unmating could be catastrophic, making the locking feature essential in industrial, transportation, and ruggedized system applications.
How does the TFC-146-02-LM-D-A-K compare to 0.100" pitch alternatives for high-density designs?
At 0.050" pitch, the TFC-146-02-LM-D-A-K provides approximately twice the contact density per millimeter compared to standard 0.100" pitch connectors. This means the same 92 signals can be routed in roughly half the connector length, freeing up valuable PCB space in dense designs like multi-layer backplanes or compact embedded computing boards.
