Frequently Asked Questions
How many positions does the TFC-137-02-FM-D-A-K provide and how are they arranged?
The TFC-137-02-FM-D-A-K provides 74 total positions arranged in a dual-row configuration at 0.050" (1.27 mm) pitch, with 37 contacts per row. This layout delivers a high-density signal interface in a compact board footprint, suitable for mezzanine cards and high-channel-count backplane designs requiring reliable multi-conductor connectivity.
What advantage does Tiger Eye contact technology provide in the TFC-137-02-FM-D-A-K?
Tiger Eye contact technology in the TFC-137-02-FM-D-A-K provides superior normal force compliance compared to standard stamped contacts, ensuring consistent electrical contact across 74 positions even after hundreds of mating cycles or during thermal excursions from -55°C to +125°C. This reduces contact resistance variation and improves signal integrity reliability in demanding industrial environments.
In what scenarios would TFC-137-02-FM-D-A-K offer a cost advantage over premium high-speed connectors?
The TFC-137-02-FM-D-A-K is a cost-effective choice when signal frequencies are below 1 GHz and the application requires a large 74-position dual-row interface at 0.050" pitch without the premium pricing of high-speed or controlled-impedance connectors. Designers can use it for DC and low-frequency analog signal routing in industrial control, data acquisition, and modular backplane applications where matched impedance is not required.
