What are the key features of TFM-142-05-STL-D-LC?
- Dual-row 42-position side-entry latch terminal strip at 0.050" (1.27 mm) pitch providing 84 total contacts in a compact footprint with positive mating retention
- Tiger Eye low-insertion-force contact design supports 200+ mating cycles while the STL latch mechanism prevents accidental unmating in vibration environments
- 30 µin gold over nickel contact plating maintains stable contact resistance below 20 mΩ across operating temperatures from -55°C to +125°C
What is TFM-142-05-STL-D-LC used for?
The TFM-142-05-STL-D-LC is engineered for secure high-density board-to-board interconnection in military avionics, ruggedized industrial systems, and aerospace instrumentation where 84 contacts must remain reliably mated under vibration and shock loads. The side-entry latch (STL) design provides positive mechanical retention, preventing accidental board separation in field-deployed equipment. Its dual-row 42-position layout at 0.050" pitch enables dense signal routing on constrained PCBs without sacrificing the reliability required in mission-critical subsystems.

Frequently Asked Questions
What does the STL suffix indicate for TFM-142-05-STL-D-LC and when is that latch feature critical?
The STL suffix designates a side-entry latch mechanism that locks the mated connector pair together, preventing accidental separation under vibration and shock. This feature is critical in airborne, vehicle-mounted, or handheld military equipment where connectors operating in environments with accelerations above 5G could otherwise work loose, interrupting 84 signal lines simultaneously.
How many total contacts does TFM-142-05-STL-D-LC provide, and what PCB area does it occupy?
TFM-142-05-STL-D-LC offers 84 total contacts arranged as 42 positions in a dual-row configuration at 0.050" (1.27 mm) pitch. The connector body spans approximately 53.3 mm in length, consolidating a large number of signal lines into a single strip and reducing the PCB area required compared to using multiple lower-count connectors.
Is TFM-142-05-STL-D-LC a suitable replacement for a standard TFM-142-05-D-LC in designs where field modules must be swapped under vibration?
Yes, TFM-142-05-STL-D-LC adds a side-entry latch to the same dual-row 42-position 0.050" pitch footprint as TFM-142-05-D-LC, so it is a form-compatible upgrade. The latch provides mechanical retention that prevents the 84-contact interface from separating under sustained vibration loads, making it the preferred choice when field module swap procedures must maintain connector integrity between 200+ mating cycles.
