Key Features
- 78-position dual-row layout at 0.050" (1.27 mm) pitch delivers maximum contact density in minimal board area
- Tiger Eye high-reliability contact design provides consistent wiping action and low contact resistance across all 78 positions
- Tape-and-reel (TR) packaging supports high-volume automated SMT assembly for production environments
Applications
The TFM-139-32-L-D-A-P-TR is suited for high-density, fine-pitch board-to-board interconnect in telecommunications infrastructure, industrial automation, and medical instrumentation. Its 78-position dual-row layout at 0.050-inch pitch enables routing of multiple high-speed signal, power, and control lines through a single compact connector footprint. The tape-and-reel packaging makes it compatible with automated pick-and-place assembly lines for efficient high-volume production.

Frequently Asked Questions
How many positions does the TFM-139-32-L-D-A-P-TR provide and what pitch does it use?
The TFM-139-32-L-D-A-P-TR is a 78-position, dual-row connector with a 0.050-inch (1.27 mm) contact pitch. This combination allows a large number of signal and power lines to be routed through one connector while keeping the PCB footprint compact, a key advantage in high-density telecom and computing board designs.
What advantages does the Tiger Eye contact design offer compared to standard pin-in-socket contacts at 1.27 mm pitch?
The Tiger Eye contact uses a dual-leaf wiping geometry that scrubs the mating surface during insertion, displacing oxidation and contamination to achieve low and stable contact resistance across all 78 positions. This reliability advantage is especially valuable in industrial or defense applications that experience vibration, thermal cycling, or infrequent mating cycles over a multi-year service life.
Why is tape-and-reel packaging important for the TFM-139-32-L-D-A-P-TR in production environments?
Tape-and-reel (TR) packaging feeds the 78-position connector directly into automated SMT placement equipment at typical machine speeds of thousands of placements per hour, eliminating manual loading and reducing placement errors. For high-volume builds, this cuts assembly cycle time and improves consistency compared to tray or loose packaging, particularly when the board houses dozens of fine-pitch connectors per panel.
