Key Features
- Tiger Eye locking mechanism provides positive retention on mating connector, preventing accidental unmating under vibration
- 50-position dual-row layout on 0.050" (1.27 mm) pitch delivers high signal density in a compact 1.375" body length
- Tin-over-nickel contact finish with round pin-socket contact style ensures reliable low-resistance mating across multiple cycles
Applications
The TFML-125-02-L-D-P-TR is used in board-to-board and mezzanine interconnect designs where a positive locking mechanism is required to maintain connectivity under mechanical vibration or shock, such as in ruggedized industrial computers, airborne electronics, and test equipment. Its 50-position dual-row 1.27 mm pitch interface enables high signal density in compact module stacking applications. The tape-and-reel packaging option (TR suffix) supports high-volume automated PCB assembly in manufacturing environments.

Frequently Asked Questions
How does the Tiger Eye locking system on the TFML-125-02-L-D-P-TR prevent accidental disconnection?
The Tiger Eye locking mechanism uses a cantilever retention latch integral to the connector housing that snaps positively into a receptacle on the mating header, requiring deliberate tool-free manual release to disconnect. This retention force typically exceeds 5 N per connector, preventing the 50-position dual-row interface from unseating during vibration or mechanical shock events that would cause intermittent contact faults in standard non-locking terminal strips.
What body dimensions does the TFML-125-02-L-D-P-TR occupy on a PCB layout?
The TFML-125-02-L-D-P-TR body measures 1.375 inches long, 0.225 inches wide, and 0.220 inches deep, providing a footprint of approximately 35 mm × 5.7 mm for the 50-position dual-row connector. At 0.050" (1.27 mm) pitch, the 25 positions per row span roughly 31 mm, with the body length accounting for end-cap material beyond the outermost contacts.
Does the TR suffix on the TFML-125-02-L-D-P-TR indicate tape-and-reel packaging for automated assembly?
Yes, the TR suffix designates tape-and-reel packaging, meaning the TFML-125-02-L-D-P-TR ships on reels compatible with standard pick-and-place equipment operating at 0.050" (1.27 mm) component pitch feeders. This packaging is essential for surface mount production lines assembling hundreds or thousands of boards per shift, where manual insertion of a 50-position dual-row connector would be impractical and inconsistent.
