Key Features
- 42-position dual-row Tiger Eye terminal strip at 0.050" (1.27 mm) pitch for cost-effective high-density PCB connections
- Tiger Eye contact system delivers reliable wiping action and low insertion force for repeatable mating cycles
- Left-angle mount (LM) orientation enables horizontal board edge mounting in space-constrained enclosures
Applications
The TFC-121-02-LM-D-A-K is ideal for cost-sensitive industrial and consumer electronics designs requiring reliable 42-pin dual-row board-to-board or board-to-cable termination at 0.050" pitch. Its left-angle configuration makes it well suited for compact PCB assemblies where vertical height is restricted. The Tiger Eye contact design ensures consistent electrical contact across 42 positions in high-cycle applications.

Frequently Asked Questions
How many positions does the TFC-121-02-LM-D-A-K provide and what is its contact pitch?
The TFC-121-02-LM-D-A-K provides 42 positions arranged in a dual-row configuration at 0.050" (1.27 mm) pitch, enabling dense PCB-level termination suitable for compact electronics assemblies.
What advantage does the Tiger Eye contact system offer in the TFC-121-02-LM-D-A-K?
The Tiger Eye contact mechanism provides a reliable wiping and self-cleaning action on mating, reducing contact resistance over multiple mating cycles across all 42 positions and improving long-term signal integrity.
Is the TFC-121-02-LM-D-A-K appropriate for space-constrained PCB designs?
Yes, the left-angle mount (LM) orientation of the TFC-121-02-LM-D-A-K allows horizontal edge mounting, reducing vertical clearance requirements and making it an excellent choice for compact 42-pin interconnect layouts.
