Frequently Asked Questions
What contact technology does the S2M-143-01-L-D use, and what advantages does it provide over standard pin sockets?
The S2M-143-01-L-D uses Samtec's Tiger Eye contact technology, which provides a four-point contact interface rather than a single-point connection. This design delivers lower insertion force while maintaining superior contact retention across 86 positions at 2.00 mm pitch, reducing wear during repeated mating cycles and improving reliability in vibration-prone installations.
For which wiring harness or panel-build scenarios is the S2M-143-01-L-D most appropriate?
This connector suits wiring harnesses requiring 86 discrete wire terminations at 2.00 mm pitch, common in industrial control cabinets, aerospace avionics bays, and defense electronics assemblies. Its discrete wire socket design allows individual wire insertion and replacement in the field without soldering, making it practical for maintenance-intensive applications with long service life requirements.
How does the 2.00 mm pitch of S2M-143-01-L-D compare to finer-pitch alternatives for high-channel-count designs?
At 2.00 mm pitch, the S2M-143-01-L-D provides greater mechanical robustness and easier wire termination compared to 1.27 mm or 1.00 mm pitch connectors, while still accommodating 86 positions in a manageable footprint. The wider pitch supports heavier gauge wire and reduces cross-talk risk, making it preferred for power-signal mixed harnesses where fine-pitch connectors would be mechanically fragile.
