Frequently Asked Questions
What contact arrangement does the TFC-123-02-FM-D-A-K use and how does it benefit PCB density?
The TFC-123-02-FM-D-A-K uses 46 contacts in a dual-row (23x2) format at a 0.050" (1.27 mm) pitch. This configuration doubles the contact count per unit length compared to single-row options, enabling high-density signal routing on daughter cards and industrial I/O boards within a constrained PCB footprint.
How does the Tiger Eye contact in the TFC-123-02-FM-D-A-K reduce assembly effort?
The Tiger Eye contact geometry in the TFC-123-02-FM-D-A-K requires significantly lower insertion force — approximately 0.3 N per contact — compared to standard tuning fork contacts. With 46 positions, this reduces total mating force by several Newtons, making hand-mating feasible in prototyping and field-service scenarios while maintaining reliable electrical contact resistance below 50 mΩ.
In what production volume scenarios does the TFC-123-02-FM-D-A-K's cost-effective design deliver the greatest advantage?
The TFC-123-02-FM-D-A-K is most cost-competitive in medium- to high-volume production runs of 500 or more units, where its lower per-connector price versus premium-grade alternatives reduces aggregate BOM cost substantially. Industrial controllers, telecom line cards, and test instruments using 46-position 0.050" interconnects are typical beneficiaries of this cost-effective strip design.
