Key Features
- 56-position dual-row design at 0.050 inch (1.27 mm) pitch delivers 112 total contacts in a space-efficient footprint for mid-to-high density PCB-to-PCB signal routing
- Tiger Eye contact technology provides a dual-beam wiping mating action that maintains low contact resistance and reliable electrical performance across repeated mate-unmate cycles
- Cost-effective terminal strip design reduces per-pin BOM cost compared to premium mezzanine or high-speed differential connectors, ideal for standard signal and mixed-power routing applications
Applications
The TFC-128-02-FM-D-A is designed for board-to-board interconnect applications in embedded computing platforms, industrial control systems, and FPGA expansion cards requiring 112 contacts at 0.050 inch pitch. Its Tiger Eye contact mechanism ensures reliable performance in environments with repeated board swaps, such as modular industrial equipment or test fixture interfaces. This terminal strip is also suitable for multi-channel data acquisition boards and communication interface modules where routing a large number of signal lines between stacked PCBs efficiently and cost-effectively is a design priority.

Frequently Asked Questions
How many total contacts does the TFC-128-02-FM-D-A provide, and how are they configured?
The TFC-128-02-FM-D-A is a dual-row terminal strip with 56 positions per row, delivering 112 total contacts at 0.050 inch (1.27 mm) pitch. This configuration supports mid-to-high density board-to-board connections, such as 96-bit parallel buses with additional control and power pins, or 112-channel sensor interface arrays between stacked PCBs in compact embedded systems.
What mating reliability advantage does the Tiger Eye contact provide in the TFC-128-02-FM-D-A?
The Tiger Eye contact in the TFC-128-02-FM-D-A uses a dual-beam wiping action during each insertion cycle, which mechanically removes oxidation from all 112 contact surfaces. This wiping action keeps contact resistance consistently low—typically under 20 milliohms per contact—and extends reliable electrical life over hundreds of mating cycles, making the connector well-suited for modular industrial equipment and test fixtures with frequent board swaps.
When is the 56-position TFC-128-02-FM-D-A a better fit than the 44-position or 70-position TFC variants?
The TFC-128-02-FM-D-A with 112 contacts is the right choice when a design needs more than 88 contacts (44-position dual-row) but fewer than 140 contacts (70-position dual-row), such as a 96-bit parallel memory bus with 16 additional control lines, or a 112-channel mixed-signal I/O card. Choosing the exact 56-position variant minimizes unused contacts and reduces connector footprint length compared to larger TFC series options.
What assembly process is the TFC-128-02-FM-D-A compatible with, and how does the FM designation affect soldering?
The FM designation in TFC-128-02-FM-D-A indicates a through-hole mount variant with a termination style suited to wave soldering and selective soldering processes. The 112-pin connector can be placed using standard through-hole insertion equipment and soldered efficiently on a wave solder line, supporting high-volume PCB manufacturing with consistent solder joint quality across all 112 contact positions without requiring manual soldering.
