Key Features
- 46-position dual-row Tiger Eye high-reliability locking terminal strip with 0.050 inch (1.27 mm) pitch
- Tiger Eye locking mechanism provides positive mating retention to prevent accidental unmating under vibration
- Ultra-fine 1.27 mm pitch enables extremely high contact density in compact PCB footprints
- High-reliability design suited for aerospace, defense, and industrial applications requiring MIL-grade connector performance
- RoHS compliant Pb-free construction with tape-and-reel packaging for automated SMT assembly
- Dual-row configuration supports 46 independent contacts in a very small board footprint
Applications
The TFML-123-02-S-D-P-TR is designed for high-reliability board-to-board interconnects in avionics, military electronics, and industrial ruggedized systems where the Tiger Eye locking feature prevents unmating under shock and vibration loads exceeding MIL-STD-810 requirements. Its 0.050 inch pitch and 46-pin dual-row layout are ideal for dense signal routing in compact embedded processor modules, radar signal processing boards, and satellite communication subsystems.

Frequently Asked Questions
How does the Tiger Eye locking mechanism on TFML-123-02-S-D-P-TR prevent connector unmating in high-vibration environments?
The Tiger Eye locking design on TFML-123-02-S-D-P-TR uses a positive-retention latch that mechanically locks all 46 pins in the mated position, requiring deliberate actuator depression to unmate. This retains connector integrity under vibration levels specified in MIL-STD-810 and IEC 60068-2-6 environmental testing.
What is the pin pitch of TFML-123-02-S-D-P-TR, and how does it compare to standard 2.54 mm pitch connectors in terms of board space savings?
TFML-123-02-S-D-P-TR uses a 0.050 inch (1.27 mm) pitch, which is exactly half of the standard 0.100 inch (2.54 mm) pitch. This halves the connector body length to approximately 29 mm for 23 positions per row, allowing 46-pin interfaces to fit in board spaces where a 2.54 mm pitch equivalent would require twice the PCB real estate.
Is TFML-123-02-S-D-P-TR suitable for lead-free reflow assembly, and what tape-and-reel packaging does it ship in?
Yes, TFML-123-02-S-D-P-TR carries the TR suffix indicating standard tape-and-reel packaging for automated pick-and-place assembly. It is Pb-free RoHS compliant, compatible with lead-free reflow solder profiles peaking at 260°C, making it suitable for high-volume SMT production lines.
When a 46-pin interface design needs extreme connector longevity in a satellite or avionics platform, why choose TFML-123-02-S-D-P-TR over a standard terminal strip?
For satellite and avionics platforms requiring 46-pin connectivity over a 15 to 20 year operational lifespan, TFML-123-02-S-D-P-TR's Tiger Eye locking design maintains mated position under 20 g vibration and thermal cycling from -55°C to +125°C, whereas standard non-locking terminal strips risk partial unmating that standard terminal strips cannot prevent under equivalent environmental stresses.
