What are the key features of TFM-134-32-LM-D-A-P-TR?
- Tiger Eye dual-beam contact provides consistent wiping action and contact resistance typically below 20 mΩ across 68 pins at 0.050" (1.27 mm) pitch
- Polarization (-P) keying physically blocks reversed insertion on the 68-pin interface, preventing board damage at 1.8 V to 3.3 V logic rails
- Low-profile SMT termination (-LM) minimizes connector height above PCB surface for use in slim enclosures with limited vertical clearance
- Tape and reel (-TR) packaging supports continuous automated SMT placement for high-volume production
What is TFM-134-32-LM-D-A-P-TR used for?
The TFM-134-32-LM-D-A-P-TR is well-suited for board-to-module and daughtercard interconnections in networking equipment, embedded computing, and data acquisition platforms requiring 68 signal lines at fine 0.050" pitch. Its low-profile SMT footprint enables use in compact multi-board assemblies where total PCB stack height must remain below 10 mm. Polarization keying ensures correct orientation during both automated reflow assembly and manual module replacement in the field.

Frequently Asked Questions
What total contact count and pitch does the TFM-134-32-LM-D-A-P-TR support for board-to-board connections?
The TFM-134-32-LM-D-A-P-TR supports 68 total contacts in a dual-row arrangement of 34 per row at a 0.050" (1.27 mm) pitch. This provides a 43.2 mm mating length for the 34-position row, which is roughly half the board space required by an equivalent 0.100" pitch connector carrying the same number of signals.
How does the low-profile (-LM) SMT termination of the TFM-134-32-LM-D-A-P-TR benefit compact multi-board assemblies?
The low-profile SMT termination reduces the connector's above-board height compared to standard-profile SMT or through-hole variants. For multi-board stacks where total assembly height must stay below 10 mm, the -LM profile allows the mated connector pair to consume less vertical space, enabling thinner enclosures in applications such as embedded single-board computers, medical devices, and portable instruments.
In an FPGA design with 68 GPIO signals routed through the TFM-134-32-LM-D-A-P-TR, what signal integrity advantage does Tiger Eye contact technology provide?
Tiger Eye dual-beam contacts maintain stable contact resistance below 20 mΩ per pin even after multiple mate and unmate cycles. For 68 FPGA GPIO signals operating at 1.8 V logic, this low and consistent contact resistance minimizes voltage drop and impedance discontinuities at the connector interface, which is critical for maintaining signal eye diagrams at data rates above 500 Mbps per lane.
When is TFM-134-32-LM-D-A-P-TR preferable to a non-polarized 68-pin connector of the same pitch?
Polarization is especially important on 68-pin fine-pitch connectors because the symmetric dual-row layout looks identical from both orientations. Without the -P keying feature, there is a 50% chance of reversed insertion during assembly or field replacement, which would connect supply rails typically at 3.3 V to ground signals and damage ICs on both boards. The polarization tab costs no additional board space and eliminates this failure mode entirely.
