Frequently Asked Questions
How many positions does the TFC-129-02-FM-D-A-K provide, and what contact pitch is used?
The TFC-129-02-FM-D-A-K is a dual-row terminal strip with 58 total positions at a 0.050" (1.27 mm) pitch. This contact density allows designers to route 58 simultaneous signal or power lines between PCBs in a compact footprint, making it a strong choice for mezzanine and daughter card interconnect applications.
What is the Tiger Eye contact technology in the TFC-129-02-FM-D-A-K, and why does it matter for reliability?
SAMTEC's Tiger Eye contact technology features a bifurcated, beam-style contact that provides an enhanced wiping action during mating. This self-cleaning mechanism removes surface oxidation and contamination, ensuring low and stable contact resistance across repeated mating cycles—critical for reliable signal transmission in telecom, industrial, and test equipment applications with 58 contacts per connector.
For which cost-sensitive PCB interconnect designs is the TFC-129-02-FM-D-A-K a strong fit?
The TFC-129-02-FM-D-A-K targets cost-sensitive, high-volume designs including consumer electronics modules, industrial control daughter cards, and data acquisition boards where 58 connections at 0.050" pitch are needed at a lower unit price. It provides comparable signal integrity to premium alternatives while reducing bill-of-materials cost in production runs of thousands of units.
Can the TFC-129-02-FM-D-A-K be used in dual-row mating configurations with SAMTEC socket strips?
Yes, the TFC-129-02-FM-D-A-K mates with compatible SAMTEC 0.050" pitch dual-row socket strips, forming a complete board-to-board pair. The dual-row 58-position layout supports board stack heights adjustable via matched socket strip height options, enabling flexible mechanical design for mezzanine assemblies requiring precise 0.050" pitch alignment.
