Key Features
- 66 positions at 0.050" (1.27 mm) pitch enabling twice the density of standard 0.100" terminal strips in the same board footprint
- Tiger Eye contact technology providing reliable low-insertion-force mating for repeated connect-disconnect cycles
- Dual-row configuration with 33 positions per row supporting high signal count cable-to-board harness interfaces
- Tape-and-reel packaging with -TR suffix enabling automated SMT pick-and-place production for high-volume assemblies
Applications
The TFC-133-02-LM-D-A-K-TR is used in high-density cable-to-board interfaces for compact embedded systems, FPGA development platforms, and test instrumentation requiring 66 signals across a 0.050" pitch connector. Its Tiger Eye contact design supports fine-pitch ribbon cable assemblies where standard 0.100" pitch connectors would consume twice the PCB area. The tape-and-reel format makes it suitable for automated assembly of communication equipment, medical devices, and portable industrial instruments demanding dense and reliable interconnects.

Frequently Asked Questions
How does the 0.050" pitch of TFC-133-02-LM-D-A-K-TR reduce PCB area compared to 0.100" connectors?
The 0.050" (1.27 mm) pitch of the TFC-133-02-LM-D-A-K-TR places contacts at half the spacing of a standard 0.100" terminal strip, so 66 positions occupy the same board length as only 33 positions on a 0.100" connector. This density advantage is critical in compact embedded systems and portable instruments where PCB real estate is limited and multiple high-pin-count interconnects must coexist in a small area.
What is the Tiger Eye contact feature and why does it matter for repeated mating cycles?
SAMTEC's Tiger Eye contact is a stamped metal contact with a distinctive eye-shaped mating beam that provides consistent normal force and low insertion force across thousands of mating cycles. For the TFC-133-02-LM-D-A-K-TR with 66 positions, this means the total mating force remains manageable even as pin count scales, and contact resistance stays below typical thresholds of a few milliohms per pin throughout the rated cycle life, making it reliable for maintenance-intensive equipment.
Which high-signal-count cable assemblies are compatible with TFC-133-02-LM-D-A-K-TR?
TFC-133-02-LM-D-A-K-TR is compatible with SAMTEC's matching cable assemblies designed for 0.050" pitch dual-row terminal strips, including flat flexible cables and micro-pitch ribbon cable harnesses with 66 conductors. Designers integrating FPGA evaluation boards or multi-lane data acquisition modules can use this connector to route 66 digital or analog signals between a host board and a daughtercard without the bulk of larger 0.100" pitch connectors.
When is TFC-133-02-LM-D-A-K-TR a better choice than a board-to-board connector for linking two PCBs?
TFC-133-02-LM-D-A-K-TR is preferred over a rigid board-to-board connector when the two PCBs are mechanically separated by more than a few millimeters or must flex relative to each other, since the cable harness accommodates misalignment and vibration. The 0.050" pitch keeps the 66-pin cable slender — about 42 mm wide — compared to the wider harness that a 0.100" pitch alternative would require, fitting within tight enclosure channels in portable medical or industrial instruments.
