Frequently Asked Questions
What is Tiger Eye contact technology in the TFM-140-12-L-D, and how does it improve performance?
Tiger Eye is SAMTEC's proprietary contact beam geometry that provides a larger contact wiping area and lower insertion force compared to conventional stamped contacts. In the TFM-140-12-L-D, this technology ensures reliable electrical connection across all 80 positions with contact resistance typically below 20 milliohms, even after repeated mating cycles. The technology is especially valuable in high-vibration or frequent mating environments such as test fixtures and removable module interfaces.
What is the contact finish specification of the TFM-140-12-L-D and how does it affect longevity?
The TFM-140-12-L-D features 15 microinch gold plating over 50 microinch nickel on the mating contact surfaces, with tin over nickel on the termination side. The gold-over-nickel finish delivers stable contact resistance below 20 milliohms, resists oxidation at temperatures from -55°C to +125°C, and supports a minimum of 500 mating cycles. This dual-layer finish is standard in high-reliability connector applications including aerospace, defense, and industrial instrumentation.
Is the TFM-140-12-L-D compatible with SAMTEC SFM series socket strips for mezzanine board-to-board stacking?
Yes, the TFM-140-12-L-D mates with SAMTEC SFM series high-reliability socket strips that share the 1.27 mm (0.050 inch) dual-row pitch. The dual-row 80-position through-hole male header and its matching SFM socket create a board-to-board stacking interface suitable for mezzanine module designs, FPGA daughter cards, and piggyback boards. Stack heights are determined by the selected SFM mating receptacle, which is available in heights from 4 mm to over 20 mm.
When should engineers choose TFM-140-12-L-D over a surface mount alternative for board-to-board connections?
The TFM-140-12-L-D through-hole configuration is preferred when mechanical retention strength must exceed 10 N pull force, when the connector will experience significant vibration or shock per MIL-STD-810, or when the application requires reworkable joints for maintenance. Through-hole soldering provides greater board adhesion than SMT pads alone, making TFM-140-12-L-D the better choice for ruggedized 80-pin interface applications in military, aerospace, or heavy industrial environments compared to surface mount TFM variants.
