Key Features
- Tiger Eye 2-point redundant contact wiping design ensures reliable low-resistance connections across 36 positions in high-vibration and high-cycle-count aerospace and defense environments
- 0.050-inch (1.27 mm) pitch dual-row layout provides 36 contacts in a compact SMT footprint, enabling dense mezzanine board stacking where 0.100-inch pitch would require twice the PCB area
- Tape-and-reel (TR) packaging with polarizing peg supports high-volume automated pick-and-place assembly with consistent orientation and alignment accuracy
Applications
The TFM-118-01-LM-D-A-P-TR is designed for high-density 36-position board-to-board interconnection in military avionics, rugged embedded computing, and high-speed data acquisition systems requiring 0.050-inch pitch SMT connectors with proven contact reliability. Its Tiger Eye contacts provide redundant wiping action suited for backplane mezzanine modules and FPGA daughter card assemblies subject to thermal cycling and mechanical shock. The tape-and-reel format supports automated SMT production lines for high-reliability electronics.

Frequently Asked Questions
What position count and pitch does the TFM-118-01-LM-D-A-P-TR provide for mezzanine board stacking?
The TFM-118-01-LM-D-A-P-TR is a 36-position dual-row terminal strip at 0.050-inch (1.27 mm) pitch, providing 18 pins per row across a compact SMT footprint. This configuration supports 36 simultaneous signal or mixed-signal connections between stacked PCBs, enabling dense mezzanine interconnection in embedded computing and avionics modules where 0.100-inch pitch connectors would require approximately twice the PCB board-edge length.
How does the Tiger Eye contact design in TFM-118-01-LM-D-A-P-TR maintain reliable connections after thermal cycling?
The Tiger Eye contact geometry creates 2 independent contact wipe points per pin during mating, so even if one contact point develops oxidation after repeated thermal cycling between -55°C and +125°C, the second wipe point maintains a low-resistance electrical path. This redundant wiping is critical in aerospace and defense applications where 36-position connectors experience repeated thermal excursions and cannot be reworked after installation.
Why do high-volume production lines specify the tape-and-reel variant TFM-118-01-LM-D-A-P-TR instead of a bulk-tray version?
The tape-and-reel packaging of TFM-118-01-LM-D-A-P-TR enables automated pick-and-place machines to feed the 36-position 0.050-inch pitch connector continuously without operator intervention, supporting production rates of hundreds of boards per shift. Bulk-tray versions require manual placement or feeder reloads that slow throughput, while tape-and-reel maintains consistent component orientation across the dual-row 36-pin footprint to prevent misalignment defects during reflow soldering.
