What are the key features of TFC-147-02-LM-D-A-K?
- 94-position dual-row 0.050" (1.27 mm) pitch configuration routes up to 94 signals in a compact approximately 2.35 inch body for high-density backplane designs
- Tiger Eye contact geometry delivers high normal force ensuring reliable electrical contact and low contact resistance across hundreds of mating cycles
- Low-profile right-angle through-hole mount (LM) reduces stack height for panel-edge and chassis-constrained board stacking applications
What is TFC-147-02-LM-D-A-K used for?
The TFC-147-02-LM-D-A-K is designed for high-density horizontal board stacking and panel-edge signal routing in telecommunications backplanes, server blade interconnects, and industrial automation controllers requiring 94 dual-row connections at 1.27 mm pitch. Its low-profile right-angle orientation minimizes PCB stack height while presenting the mating interface at the board edge for simplified cable or mating connector access inside compact enclosures. Paired with SAMTEC SFM or TSM series sockets, it provides a matched 94-position interconnect system with low contact resistance across high-cycle applications.

Frequently Asked Questions
What is the body length of TFC-147-02-LM-D-A-K and how does it handle 94 positions at 1.27 mm pitch?
The TFC-147-02-LM-D-A-K accommodates 94 positions in a dual-row layout at 0.050" (1.27 mm) pitch, resulting in a body length of approximately 2.35 inches. This compact span makes it one of the highest-density through-hole terminal strip options in the TFC series, fitting 94 signals into a footprint that a 2.54 mm pitch connector would need approximately 4.70 inches to match, delivering roughly 50% PCB length savings.
How does the low-profile mount (LM) option of TFC-147-02-LM-D-A-K differ from a standard right-angle configuration?
The LM (low-profile mount) suffix on TFC-147-02-LM-D-A-K specifies a right-angle orientation where the mating interface is positioned closer to the PCB surface than a standard right-angle version, reducing the height above the PCB to typically below 6 mm. This is critical in chassis-mounted telecom blade assemblies and server mezzanine cards where adjacent PCBs or thermal management components restrict vertical clearance while 94 signals must still be accessible from the board edge.
For a 94-position high-cycle backplane application, why choose TFC-147-02-LM-D-A-K over a card-edge connector solution?
The TFC-147-02-LM-D-A-K offers the advantage of a discrete mated pair with Tiger Eye socket contacts delivering up to 500 insertion cycles and contact resistance below 20 mΩ per pin, which is significantly more predictable than card-edge gold-finger connections that depend on PCB plating quality and wear. For 94-position backplane designs in telecom or industrial equipment expected to undergo repeated board extraction over a 10-year to 15-year service life, the TFC-series discrete connector approach provides controlled contact force, replaceability, and consistent 1 A per pin current handling without PCB gold-finger replating.
