What are the key features of TFC-146-02-LM-D-A?
- 92-position dual-row layout at 0.050" (1.27 mm) pitch delivers exceptionally high contact density for signal-intensive commercial designs
- LM surface-mount tail termination enables automated reflow soldering in high-volume PCB assembly environments
- Tiger Eye cost-effective contact design keeps per-connector cost low in large-quantity commercial production
- Compact body footprint accommodates 92 signal lines in a single connector, reducing PCB area versus multiple smaller connectors
What is TFC-146-02-LM-D-A used for?
The TFC-146-02-LM-D-A is designed for very high-density board-to-board and backplane interconnect in networking switches, large-scale industrial controllers, and high-channel-count data acquisition systems requiring 92 contact positions at 0.050" pitch. Its LM surface-mount tails allow integration with standard automated reflow soldering processes, making it compatible with high-volume manufacturing lines. The Tiger Eye construction offers a cost-optimized path to 92-pin connectivity in commercial electronics without the premium pricing of high-reliability connector series.

Frequently Asked Questions
How many signal contacts does the TFC-146-02-LM-D-A support, and what pitch are they arranged on?
The TFC-146-02-LM-D-A supports 92 signal contacts in a dual-row arrangement at 0.050" (1.27 mm) pitch. This is one of the higher contact counts in the TFC Tiger Eye series, making it suitable for applications such as large backplane modules, high-channel sensor arrays, or FPGA interface boards where routing many signal lines through a single connector is required.
What does the LM tail designation mean for the assembly process of the TFC-146-02-LM-D-A?
The LM tail designation indicates a surface-mount termination profile optimized for automated reflow soldering at peak temperatures up to approximately 260°C. Pick-and-place equipment positions the 92-pin connector on a 1.27 mm pitch SMT land pattern, and the board passes through the reflow oven, creating reliable solder joints across all 92 positions simultaneously without any hand-soldering steps.
For what commercial applications does a 92-position connector at 0.050" pitch offer a design advantage?
A 92-position connector at 0.050" pitch offers significant advantage in networking switch line cards where dozens of differential pairs and control signals must cross a module boundary, and in industrial automation where PLC I/O expansion cards route many discrete and analog channels through a single board interface. The TFC-146-02-LM-D-A consolidates all 92 signals into a footprint small enough to fit in tight PCB zones that multiple smaller connectors could not.
How does the TFC Tiger Eye series differ from SAMTEC's premium connectors in terms of cost and lifecycle fit?
The TFC Tiger Eye series is cost-optimized for commercial-grade applications with moderate lifecycle requirements, typically suited for products with operational lifespans of 5 to 10 years and mating cycle counts in the hundreds. Premium SAMTEC series such as the SFM target aerospace and defense applications requiring mating cycles above 1000, temperatures from -55°C to +125°C, and qualification to MIL-STD standards. Choosing the TFC-146-02-LM-D-A over a premium equivalent can reduce connector cost by 30% or more in large production volumes.
