What are the key features of TFM-142-32-STL-D-A-P-TR?
- 84 total contacts in 42-per-row dual-row layout at 0.050" (1.27 mm) pitch for ultra-high-density mezzanine and stacking board interconnects
- Straddle-mount (STL) SMT termination style enabling board-edge installation without through-holes, reducing PCB layer congestion on dense multilayer designs
- Tiger Eye 4-point wiping contact system delivering reliable low-resistance mating across hundreds of insertion cycles for high-reliability industrial and defense applications
What is TFM-142-32-STL-D-A-P-TR used for?
The TFM-142-32-STL-D-A-P-TR targets ultra-dense board-edge mezzanine connections in FPGA carrier systems, test-and-measurement equipment, and defense avionics modules where 84 signals must traverse a compact 1.27 mm pitch interface. Its straddle-mount termination style clamps over the PCB edge, eliminating drilled holes and reducing impedance discontinuities at the board edge compared to through-hole alternatives. The tape-and-reel packaging supports automated SMT production lines in high-volume industrial and communications hardware manufacturing.

Frequently Asked Questions
What total contact count and pitch does TFM-142-32-STL-D-A-P-TR offer for a high-density mezzanine design?
The TFM-142-32-STL-D-A-P-TR provides 84 total contacts—42 per row in a dual-row arrangement—at 0.050" (1.27 mm) pitch. This density is approximately double that of a 2.54 mm pitch connector in the same board footprint length, allowing 84 independent signal or power lines to interconnect between stacked PCBs in compact FPGA daughter-card and test instrumentation module designs.
How does the straddle-mount (STL) termination of TFM-142-32-STL-D-A-P-TR differ from standard SMT pads for board-edge installation?
The straddle-mount style places SMT pads on both the top and bottom faces of the PCB edge simultaneously, clamping the connector body over the board edge and providing mechanical retention through the clamping action without requiring through-hole drilling. This eliminates the need for 84 drilled via holes, reduces manufacturing steps, and can improve signal integrity at frequencies above 500 MHz by avoiding via stub reflections common in through-hole edge connectors.
In what way is TFM-142-32-STL-D-A-P-TR better suited than TFM-142-series vertical SMT variants for space-constrained backplane designs?
The straddle-mount TFM-142-32-STL-D-A-P-TR installs flush at the PCB edge and adds minimal height above the board surface compared to vertical SMT variants that project upward by 5 mm or more. For backplane designs with a board-to-board stack height constraint of less than 10 mm and requiring 84 signals at 1.27 mm pitch, the straddle-mount version maximizes usable space while maintaining the same Tiger Eye contact reliability and tape-and-reel manufacturability.
