What are the key features of TFM-137-32-FM-D-A-P-TR?
- Tiger Eye contact technology delivers robust mating retention across 74 dual-row positions at 0.050 inch pitch for high-reliability board-to-board interconnects
- Floating mount (FM) design accommodates PCB misalignment up to ±0.5 mm, reducing stress on solder joints in thermally cycled assemblies
- Polarization keying and pick-and-place tape reel packaging combine to prevent mis-mating and enable automated SMT assembly in volume production
- 32 mm mating height option allows larger PCB-to-PCB separation for routing power and signal cables between stacked boards in chassis-mounted systems
What is TFM-137-32-FM-D-A-P-TR used for?
The TFM-137-32-FM-D-A-P-TR is used in board-to-board interconnect applications within communications infrastructure, industrial automation systems, and embedded computing platforms that require tolerance for PCB misalignment. Its 74-position dual-row layout supports wide data buses and mixed signal/power interfaces, while the floating mount feature absorbs mechanical stress during thermal cycling between -40°C and +85°C. The tape reel packaging and pick-and-place compatibility make it efficient for automated SMT assembly in high-volume production of network interface modules and control boards.

Frequently Asked Questions
What does the floating mount (FM) feature of the TFM-137-32-FM-D-A-P-TR provide in a thermally cycled assembly?
The floating mount feature allows lateral PCB misalignment compensation of up to ±0.5 mm during mating, which absorbs differential thermal expansion between two PCBs cycling from -40°C to +85°C. Without this compliance, misalignment forces would transfer directly to the SMT solder joints across all 74 positions, increasing fatigue crack risk and reducing connector service life in industrial environments.
How many positions does the TFM-137-32-FM-D-A-P-TR provide, and what is the contact pitch?
The TFM-137-32-FM-D-A-P-TR provides 74 positions in 2 rows at 0.050 inch (1.27 mm) pitch. With 37 contacts per row, it supports wide parallel buses, multi-channel ADC data lines, or combined power and ground distributions across a single dual-row connector for industrial control and signal processing boards.
How does the 32 mm mating height variant of the TFM-137 series compare to shorter mating heights in chassis-mounted designs?
The 32 mm board-to-board separation defined by the 32 suffix provides adequate vertical clearance for routing power cables and shielded signal traces between stacked PCBs inside a chassis. Shorter mating heights in the 4 mm to 12 mm range are used in tight stack assemblies, whereas the 32 mm variant is selected when inter-board space must accommodate components taller than 20 mm or harness connectors rated for 5 A per circuit.
What production efficiency advantages does the tape reel packaging provide for the TFM-137-32-FM-D-A-P-TR?
The TR (tape reel) format loads directly into standard SMT pick-and-place feeders, enabling placement speeds of 500 to 2000 connectors per hour without manual staging. Combined with the pick-and-place (P) vacuum pad feature, the packaging ensures reliable pick success rates above 99.5 percent for the 74-position dual-row body, which is critical for high-volume PCB assembly lines processing thousands of boards per day.
