Frequently Asked Questions
What is the pin configuration of the TFC-126-02-LM-D-A-K and its contact pitch?
The TFC-126-02-LM-D-A-K has 52 total positions arranged in 2 rows of 26 contacts, with a 0.050-inch (1.27 mm) contact pitch. This dual-row configuration at 1.27 mm pitch enables routing of 52 signals across a significantly shorter connector length compared to single-row alternatives.
For which PCB-level scenarios is a 52-pin 0.050-inch pitch terminal strip a better fit than a 64-pin alternative?
A 52-pin TFC-126 is the right selection when the design requires exactly 52 or fewer signals, avoiding the unnecessary extra 12 pins of a 64-pin connector that would increase connector size and cost. Compact SBCs, sensor fusion modules, and 32-bit MCU breakout boards with limited I/O counts typically fall in this 52-pin range.
Can the TFC-126-02-LM-D-A-K be used for mixed signal and power distribution on the same connector?
Yes, the TFC-126-02-LM-D-A-K supports mixed use of its 52 contacts for both digital signals and low-current power lines, typically rated up to 1 A per contact at the 0.050-inch pitch. Designers commonly allocate several pins for 3.3 V or 5 V power and ground returns while using the remaining pins for data and control signals.
