What are the key features of TFC-117-02-LM-D-K-TR?
- 34 positions in a dual-row layout on ultra-fine 0.050" (1.27 mm) pitch for high-density board connections
- Tiger Eye contact design provides reliable, low-insertion-force mating with consistent electrical performance
- K keying option prevents incorrect connector orientation in multi-connector PCB assemblies
- LM low-profile mounting minimizes connector height for compact system designs
- Tape-and-reel (TR) packaging supports automated pick-and-place SMT assembly
What is TFC-117-02-LM-D-K-TR used for?
The TFC-117-02-LM-D-K-TR is suited for high-density PCB-to-PCB and board-to-cable interconnects in compact embedded computing modules, FPGAs, and DSP development boards where 34 positions at 0.050" pitch deliver maximum contact density in minimal footprint. The keyed design prevents assembly errors in systems with multiple adjacent connectors of different signal assignments. It also finds use in medical devices and portable instrumentation where low-profile, high-reliability board connections are critical.

Frequently Asked Questions
What pitch and position count does TFC-117-02-LM-D-K-TR offer for high-density PCB layouts?
The TFC-117-02-LM-D-K-TR provides 34 positions arranged in a dual-row configuration on a 0.050" (1.27 mm) pitch. This ultra-fine pitch delivers twice the contact density of standard 0.100" pitch connectors in the same board length, making it ideal for space-constrained FPGA breakout boards, processor modules, and high-density signal distribution applications.
How does the Tiger Eye contact design of TFC-117-02-LM-D-K-TR maintain reliable connections in vibration-prone environments?
The Tiger Eye contact design uses a bifurcated, spring-loaded contact that maintains consistent wiping force across the mating surface even under vibration and thermal cycling. At 0.050" pitch across 34 positions, the dual-contact wipe on each pin reduces the risk of intermittent connection that can occur in single-beam contacts when PCBs flex or vibrate in portable instruments or vehicle-mounted electronics.
When should designers select the K-keyed TFC-117-02-LM-D-K-TR over a non-keyed TFC variant on a multi-connector board?
The K keying option physically prevents mating the wrong connector on boards that have multiple adjacent TFC-series connectors carrying different voltage or signal assignments, such as a 3.3 V I/O bank next to a 1.8 V bank. Without keying, 34-position 0.050" pitch connectors look identical and an assembly error can apply incorrect voltage levels to sensitive FPGA or processor I/O pins. The keyed variant eliminates this risk at no significant cost penalty while maintaining the same tape-and-reel (TR) format for automated assembly.
