Frequently Asked Questions
How many positions does TFC-109-02-LM-D-A-K provide and in what row configuration?
The TFC-109-02-LM-D-A-K provides 18 total positions in a dual-row layout at 0.050" (1.27 mm) pitch, with 9 contacts per row. This compact dual-row configuration is well suited for board-to-board mezzanine connectors where a moderate pin count is needed within a small PCB footprint in industrial and embedded computing applications.
How does the Tiger Eye contact technology in TFC-109-02-LM-D-A-K maintain connection reliability in vibrating environments?
The Tiger Eye contact system in the TFC-109-02-LM-D-A-K uses a compliant contact geometry that maintains a consistent normal force across all 18 positions even when subjected to mechanical vibration or thermal cycling from -55°C to +125°C. This prevents intermittent electrical contact that could occur with standard stamped contacts in industrial PLC housings, robotics controllers, and field-deployed measurement instruments.
When is TFC-109-02-LM-D-A-K a cost-effective choice versus high-speed board stacking connectors for the same pin count?
The TFC-109-02-LM-D-A-K offers a cost-effective alternative to controlled-impedance high-speed stacking connectors when the 18-position interface carries signals below 500 MHz where impedance matching is unnecessary. For GPIO routing, power distribution, and low-frequency analog signals in embedded modules, its Tiger Eye contact system provides adequate reliability at a significantly lower cost per position than high-speed equivalents.
