Applications
The TFML-120-02-S-D-P-TR is designed for high-reliability board-to-cable and board-to-board signal interconnects in avionics, defense electronics, and test instrumentation requiring secure 40-pin locking connections at 0.050" pitch. Its shrouded housing and Tiger Eye contact technology ensure consistent signal integrity across repeated mating cycles and mechanical shock events. This connector is also used in ruggedized industrial control systems and FPGA development boards where fine-pitch density and connection security are both critical.

Frequently Asked Questions
What contact plating specification does the TFML-120-02-S-D-P-TR use, and why does it matter for reliability?
The TFML-120-02-S-D-P-TR uses 30 microinches of gold over 50 microinches of nickel plating on the mating contact surfaces. This gold-over-nickel combination delivers low and stable contact resistance across hundreds of mating cycles while resisting oxidation and corrosion, which is critical for signal integrity in aerospace and defense applications exposed to humidity and temperature cycling.
For a compact avionics board design, how does the TFML-120-02-S-D-P-TR's 0.050" pitch help with connector density?
The 0.050" (1.27 mm) pitch allows 40 positions to fit within a 1.125" body length, achieving roughly half the spacing of standard 0.100" pitch connectors. This fine pitch enables avionics and embedded computing boards to route 40 signals through a small footprint while the shrouded locking housing prevents unmating under vibration loads encountered in airborne platforms.
What does the locking feature of the TFML-120-02-S-D-P-TR provide over non-locking terminal strips?
The locking mechanism on the TFML-120-02-S-D-P-TR positively retains the mated connector pair, preventing accidental disconnection caused by cable tension, vibration, or shock. In military and aerospace assemblies where unmating could cause critical failures, this locking retention meets requirements such as those in MIL-DTL-83513 for micro-D connectors, ensuring 40 circuits remain connected across the product service life.
Is the TFML-120-02-S-D-P-TR available on tape and reel for automated SMD pick-and-place production?
Yes, the -TR suffix on TFML-120-02-S-D-P-TR designates tape-and-reel packaging, which is compatible with automated SMD pick-and-place assembly lines. With a 1-week factory lead time from SAMTEC, procurement teams can plan production schedules without extended buffer stock, supporting lean manufacturing workflows for defense and industrial electronics builds requiring 40-position fine-pitch locking receptacles.
