Key Features
- 74-position dual-row terminal strip at 0.050" (1.27 mm) pitch for high-density signal routing in compact PCB designs
- Tiger Eye contact technology provides low insertion force and reliable electrical contact even after repeated mating cycles
- Tape-and-reel (TR) packaging with surface-mount compatible footprint supports automated pick-and-place assembly in high-volume production
Applications
The TFC-137-02-FM-D-A-K-TR is designed for high-density board-to-board interconnects in embedded computing modules, FPGAs, DSP evaluation boards, and industrial data acquisition systems requiring 74-pin signal connections at 0.050" pitch. Its cost-effective Tiger Eye design suits telecommunications line cards, server backplane daughter cards, and test and measurement instrumentation where minimizing PCB footprint across 2 rows of contacts is critical.

Frequently Asked Questions
How many positions and what pitch does the TFC-137-02-FM-D-A-K-TR terminal strip provide?
The TFC-137-02-FM-D-A-K-TR features 74 total contact positions arranged in a dual-row configuration at 0.050" (1.27 mm) pitch. This high-density layout is nearly half the footprint of standard 0.100" pitch connectors, making it ideal for compact FPGA, DSP, and multi-channel data acquisition boards where 37 signals per row must be routed in minimal PCB space.
What is the Tiger Eye contact technology in the TFC-137-02-FM-D-A-K-TR and what problem does it solve?
Tiger Eye contacts in the TFC-137-02-FM-D-A-K-TR use a proprietary dual-beam contact design that provides consistent normal force across all 74 positions, reducing insertion force while maintaining reliable electrical contact after hundreds of mating cycles. This is especially beneficial in test fixture sockets and evaluation boards at 0.050" pitch where high pin counts make manual mating difficult with traditional high-force contacts.
When should an engineer prefer the TFC-137-02-FM-D-A-K-TR over a 0.100" pitch 74-pin alternative?
The TFC-137-02-FM-D-A-K-TR at 0.050" pitch occupies roughly half the board length of an equivalent 0.100" pitch connector for the same 74 positions, making it the right choice when PCB real estate is severely limited in compact modules or stacked board assemblies. Engineers working on FPGA mezzanine cards, SOM (system-on-module) interfaces, or multi-gigabit serial connections requiring tight trace routing on 2-layer or 4-layer boards benefit most from its 1.27 mm pitch density.
