Key Features
- 64-position dual-row layout on 0.050" (1.27mm) pitch provides 128 contacts for high-density mezzanine and daughter-card stacking
- Long-mating (LM) contact variant increases pin engagement depth for improved normal force and wipe length in vibration or shock environments
- Tiger Eye cost-effective design cuts BOM cost on low-to-medium-frequency board-stacking interfaces compared to high-speed connector alternatives
Applications
The TFC-132-02-LM-D-A is designed for mezzanine daughter-card and module interconnect applications in industrial computing, telecom line cards, and embedded control systems that need 64 dual-row positions at 1.27mm pitch. The long-mating contact length provides a deeper socket engagement than standard TFC variants, making the connector suitable for assemblies exposed to mechanical vibration or repeated plug-cycle use. Its surface-mount termination fits directly into automated SMT reflow lines, lowering assembly cost for medium-to-high production volumes.

Frequently Asked Questions
How does the long-mating (LM) contact option on TFC-132-02-LM-D-A differ from a standard-length TFC-132-02 contact?
The LM designation indicates the square-pin contacts are longer than the standard TFC-132-02 variant, providing approximately 0.10 to 0.15 inches of additional mating depth when engaged with a corresponding socket strip. This extended engagement increases contact wipe length and normal force, reducing the risk of intermittent connections caused by vibration, thermal expansion, or repeated insertion cycles common in industrial field equipment and test-and-measurement racks.
How many total contacts does TFC-132-02-LM-D-A provide, and how does that map to typical FPGA or processor daughter-card interfaces?
The TFC-132-02-LM-D-A offers 64 positions in a 2-row layout, yielding 128 individual contacts on a 0.050-inch (1.27mm) pitch. For an FPGA daughter card, 128 contacts can accommodate 64 single-ended LVTTL or CMOS I/O signals, 16 differential LVDS pairs, plus multiple power and ground pins—enough bandwidth for parallel data buses, SPI, I2C, and JTAG across a single mezzanine connector without daisy-chaining multiple smaller headers.
Can TFC-132-02-LM-D-A mate with the TFC-132-02-FM-D-A in the same product family?
The TFC-132-02-LM-D-A (long-mating pin strip) and TFC-132-02-FM-D-A (flat-mount pin strip) are both 64-position 0.050-inch dual-row Tiger Eye variants that plug into compatible Samtec SFM or SSW 132-position socket strips. The two pin variants differ in contact tail geometry and engagement length rather than mating footprint, so a system designer can use whichever pin variant matches their stack height and vibration requirements while sharing the same 64-position socket strip on the opposite board.
