Key Features
- 76-position dual-row 1.27 mm pitch terminal strip with Tiger Eye positive locking mechanism for secure vibration-resistant mating
- High-reliability gold-plated contacts deliver stable low-resistance connections across thousands of mating cycles in harsh environments
- Locking latch design prevents accidental unmating in aerospace, defense, and industrial equipment subject to shock and vibration
Applications
TFML-138-02-S-D-P-TR is designed for high-reliability locking board-to-board connections in aerospace avionics, military electronics, and ruggedized industrial systems where connector retention under shock and vibration is mandatory. The 76-position, 1.27 mm pitch dual-row layout supports dense I/O routing while the Tiger Eye locking feature eliminates the risk of accidental disconnection. This terminal strip is also used in medical imaging and test-and-measurement equipment where secure, repeatable connections are critical.

Frequently Asked Questions
What locking mechanism does TFML-138-02-S-D-P-TR use and why does it matter?
TFML-138-02-S-D-P-TR uses SAMTEC's Tiger Eye positive locking system, which applies a retention force that resists accidental unmating under vibration, shock, and mechanical stress. In aerospace avionics or military electronics subjected to repeated mechanical loads, this locking feature prevents intermittent disconnections that standard friction-fit connectors cannot reliably prevent.
How many positions and what pitch does TFML-138-02-S-D-P-TR support in a dual-row layout?
TFML-138-02-S-D-P-TR provides 76 total positions arranged in 2 rows of 38, on a 1.27 mm (0.050 inch) pitch. This high-density dual-row layout enables routing of up to 76 independent signals or mixed signal-and-power lines across a compact 1.27 mm pitch footprint, ideal for dense mezzanine PCB designs.
Is TFML-138-02-S-D-P-TR suitable for environments with high levels of vibration or shock?
Yes. TFML-138-02-S-D-P-TR is purpose-built for high-shock and high-vibration environments. The Tiger Eye locking retention mechanism secures the mated connector pair against separation, making it a preferred choice for airborne platforms, ground vehicles, and shipboard electronics rated for MIL-STD-810 or equivalent vibration levels.
How does the gold plating on TFML-138-02-S-D-P-TR compare to standard tin-finished connectors for long-term use?
The gold-plated contacts on TFML-138-02-S-D-P-TR maintain contact resistance typically below 30 mΩ and resist corrosion over tens of thousands of mating cycles — far exceeding the cycle life of tin-finished alternatives, which begin to degrade after a few hundred insertions. Gold plating is especially important in safety-critical applications where contact resistance drift is not acceptable.
