What are the key features of TFM-135-12-LM-D-A-P-TR?
- Tiger Eye low-insertion-force contact system provides superior signal reliability and extended mating cycle life in 70-position dual-row configurations
- Low-profile (LM) surface-mount termination at 0.050" (1.27 mm) pitch reduces PCB height requirements for slim form-factor electronic assemblies
- Polarization key and tape-and-reel (TR) packaging ensure correct orientation and high-throughput automated pick-and-place assembly in volume production
What is TFM-135-12-LM-D-A-P-TR used for?
TFM-135-12-LM-D-A-P-TR is designed for high-density board-to-board connections in slim embedded computing platforms, FPGA module carriers, and portable test instrumentation where vertical PCB clearance is constrained and signal count is high. The low-profile SMT termination and 70-position dual-row layout at 1.27 mm pitch allow compact routing of mixed signal and power rails without sacrificing connector reliability. Tape-and-reel packaging further supports scalable high-volume SMT production in industrial, telecom, and mil-aero electronics manufacturing.

Frequently Asked Questions
How many contact positions does TFM-135-12-LM-D-A-P-TR provide, and what pitch spacing does it use?
TFM-135-12-LM-D-A-P-TR provides 70 total contact positions arranged in a dual-row configuration with 35 contacts per row, all on a 0.050" (1.27 mm) pitch. This fine-pitch dual-row layout enables connection of 70 signal or power lines within a compact PCB footprint suited to FPGA carrier boards and embedded computing modules.
What does the low-profile (LM) termination style of TFM-135-12-LM-D-A-P-TR offer compared to standard SMT versions in height-constrained designs?
The LM (low-profile) termination on TFM-135-12-LM-D-A-P-TR reduces the overall PCB height contribution of the connector, enabling board-to-board stack heights below 3 mm in slim form-factor assemblies. This is advantageous in portable instruments and slim embedded compute modules where vertical clearance between PCBs is limited to under 5 mm.
When is TFM-135-12-LM-D-A-P-TR a better fit than standard 2.00 mm pitch dual-row connectors for FPGA module interfaces?
TFM-135-12-LM-D-A-P-TR is preferred over 2.00 mm pitch dual-row connectors when FPGA module interfaces require 70 connections in roughly half the PCB footprint area. At 1.27 mm pitch, the connector occupies approximately 45 mm of board length for 35 positions per row, compared to roughly 70 mm needed by a 2.00 mm pitch equivalent, directly enabling smaller module sizes.
How does the polarization feature of TFM-135-12-LM-D-A-P-TR reduce assembly errors in multi-connector PCB systems?
The polarization key on TFM-135-12-LM-D-A-P-TR physically prevents 180-degree mis-insertion of the 70-pin dual-row connector, protecting signal and power contacts from reverse-connection damage. This feature is especially critical on high-density PCBs with multiple identical 1.27 mm pitch connectors positioned within a few millimeters of each other, where visual differentiation alone is insufficient.
