What are the key features of TFC-133-02-FM-D-A?
- 66 positions in a dual-row 0.050" (1.27 mm) pitch layout offering high-density signal connectivity in a compact connector footprint
- Female machined (FM) contacts with Tiger Eye design deliver tighter dimensional tolerances and lower contact resistance than stamped alternatives
- Cost-effective terminal strip solution for applications requiring 66 signal paths without the premium cost of shielded or high-speed connector families
What is TFC-133-02-FM-D-A used for?
The TFC-133-02-FM-D-A is designed for high-density board-to-board interconnects in embedded computing carrier boards, FPGA daughter cards, and industrial multi-axis controller interfaces where 66 signal lines must be reliably connected on a 0.050" pitch. Its female machined contact construction ensures repeatable, low-resistance mating performance, making it suitable for designs that undergo periodic maintenance or module replacement.

Frequently Asked Questions
What contact construction does the FM designation indicate for the TFC-133-02-FM-D-A?
The FM designation in TFC-133-02-FM-D-A indicates female, machined contact construction. Machined contacts are manufactured to tighter dimensional tolerances than stamped contacts, resulting in more consistent normal force and lower contact resistance across all 66 positions. This improves signal integrity and ensures reliable mating performance over repeated mate-and-unmate cycles in service environments.
For a 66-signal parallel bus interface, why would an engineer select the TFC-133-02-FM-D-A over a higher-position connector?
An engineer would select the TFC-133-02-FM-D-A when exactly 66 signal lines are required, such as a 64-bit data bus with 2 additional control lines, and a larger 88-position connector would waste board space and add unnecessary cost. At 0.050" (1.27 mm) pitch, 66 positions occupy approximately 1.65 inches (42 mm) of connector length, minimizing PCB real estate while meeting the exact signal count requirement.
Which embedded computing or industrial scenarios are best served by the TFC-133-02-FM-D-A's 66-position configuration?
The 66-position TFC-133-02-FM-D-A is best suited for embedded processor module carrier boards, multi-axis motor controller daughter cards, and industrial fieldbus interface boards that need to pass 66 signals including data buses up to 32 bits wide, multiple serial channels, power references, and discrete I/O lines. The dual-row 0.050" pitch layout packs all 66 connections into a compact footprint ideal for dense PCB designs.
How does the cost-effective Tiger Eye series position the TFC-133-02-FM-D-A compared to premium SAMTEC interconnect families in terms of signal frequency support?
The Tiger Eye cost-effective series, including the TFC-133-02-FM-D-A, is optimized for applications where signal frequencies are below a few hundred MHz and differential impedance control or integrated shielding is not required. For signal frequencies above 500 MHz or designs requiring controlled 50-ohm or 100-ohm differential impedance across all 66 positions, SAMTEC's high-speed board-to-board connector families would be more appropriate despite their higher per-unit cost.
