Key Features
- 18-position dual-row connector at 0.050" (1.27 mm) pitch with key (K) alignment feature preventing incorrect mating orientation
- Latch retention mechanism secures the mated connection against accidental disconnection in vibration or shock environments
- Tiger Eye cost-effective contact design delivers reliable signal integrity across 9 contact pairs in a compact low-profile footprint
Applications
The TFC-109-02-L-D-A-K is ideal for compact module interconnections in industrial sensors, embedded computing boards, and test and measurement equipment where 18 signal connections must be reliably maintained. The key alignment feature prevents incorrect insertion during field maintenance or system assembly, reducing connector damage risk. Its 0.050" pitch dual-row layout keeps PCB footprint minimal while delivering 9 contact pairs for data, power, and control signals.

Frequently Asked Questions
What does the K suffix on TFC-109-02-L-D-A-K indicate and why is it important for field assembly?
The K suffix on TFC-109-02-L-D-A-K denotes a key or polarization feature that physically prevents incorrect mating orientation. This is critical in field assembly and maintenance scenarios where technicians may be working under poor lighting or time pressure, ensuring the 18-position connector mates correctly every time and protecting sensitive circuits from reversed connections.
For a 9-signal-pair embedded controller module, how does TFC-109-02-L-D-A-K fit within a tight PCB layout?
With 18 positions at 0.050" (1.27 mm) pitch, the TFC-109-02-L-D-A-K occupies only about 0.45 inches of board edge length for 9 contact pairs. This compact profile makes it suitable for small embedded controller modules, IoT sensor boards, and miniaturized industrial devices where PCB area is limited but 9 bidirectional signal pairs are required.
What retention mechanism does TFC-109-02-L-D-A-K provide for applications subject to mechanical vibration?
The TFC-109-02-L-D-A-K incorporates a latch retention feature that locks the connector pair together after mating, preventing accidental disconnection due to vibration, shock, or mechanical handling. This latch mechanism is particularly valuable in industrial automation equipment, transportation electronics, and robotic systems where the 18-position board connection must remain secure under continuous vibration up to several g forces.
