Frequently Asked Questions
How many pins does TFM-123-12-L-D-A-P-TR provide and what is its contact pitch?
The TFM-123-12-L-D-A-P-TR provides 46 pins arranged in a 23-position dual-row configuration on a 0.050-inch (1.27 mm) pitch. This high-density layout supports routing of 46 signals in a minimal PCB footprint, making it suitable for aerospace, defense, and industrial equipment where up to 46 outputs must be managed through a single reliable connector assembly.
What operating temperature range does TFM-123-12-L-D-A-P-TR support for harsh environment applications?
The TFM-123-12-L-D-A-P-TR Tiger Eye terminal strip is rated for continuous operation from -55°C to 125°C, covering the full range required for aerospace, defense, and industrial applications. The Tiger Eye contact design maintains high normal mating force across this entire thermal span, ensuring all 46 pins retain low-resistance connections after repeated thermal shock cycling from cold soak to elevated operating temperatures.
When should TFM-123-12-L-D-A-P-TR be selected over a standard 0.100-inch pitch dual-row connector with 46 pins?
A designer should choose the TFM-123-12-L-D-A-P-TR when board space is limited, as a 0.100-inch pitch 46-pin connector would require nearly twice the PCB length for the same signal count. The 0.050-inch Tiger Eye strip halves the connector footprint while maintaining high-reliability contacts qualified from -55°C to 125°C, making it the preferred choice for size-sensitive aerospace and defense designs with stringent 46-channel routing requirements.
