Key Features
- 66 positions in a dual-row 2.00 mm pitch layout for high-density discrete wire-to-board connectivity
- Tiger Eye contact technology providing independent spring deflection per contact for superior reliability over thousands of mating cycles
- Gold-plated contacts ensuring low and stable contact resistance, ideal for sensitive signal and low-voltage applications
- Discrete wire socket design supporting individual wire termination without requiring ribbon cable or IDC tooling
Applications
The S2M-133-01-S-D is used in aerospace, defense, and high-reliability industrial systems where 66 discrete wires must terminate reliably to a PCB at 2.00 mm pitch with guaranteed contact integrity over the product lifetime. Its Tiger Eye contact design makes it suitable for test fixtures, avionics wire harnesses, and mil-spec board interconnects where vibration and mechanical stress would compromise conventional stamped-contact sockets. It is also used in instrumentation and medical equipment requiring individually routed wires with high pin counts in a compact dual-row footprint.

Frequently Asked Questions
How many positions does the S2M-133-01-S-D provide and what is the contact pitch?
The S2M-133-01-S-D provides 66 positions arranged in a dual-row configuration with a 2.00 mm contact pitch. This means 33 contacts per row spaced at 2.00 mm centers, yielding a total connector length of approximately 66 mm for the mated row. The 2.00 mm pitch is widely used in industrial and mil-spec wire harness applications where 2.54 mm pitch connectors are too large but 1.27 mm pitch connectors are too fragile for the wire gauges used.
What distinguishes the SAMTEC Tiger Eye contact design from standard stamped socket contacts?
The SAMTEC Tiger Eye contact design uses an independent dual-beam contact geometry that provides separate spring deflection for each mating half, delivering more consistent contact force and lower contact resistance than standard stamped single-beam sockets. This independent deflection means that even when the mating pin is not perfectly centered, both beams of the Tiger Eye maintain contact, resulting in stable low resistance below 20 milliohms across thousands of mating cycles in vibration-prone environments.
In what high-reliability applications is the S2M-133-01-S-D preferred over standard 2.00 mm pitch connectors?
The S2M-133-01-S-D is preferred in avionics wire harnesses, defense electronics, and medical instruments where connector failure is not acceptable and mating cycles may exceed 500 operations over the product lifetime. Standard 2.00 mm pitch connectors with simple stamped contacts can develop high contact resistance after repeated mating or in environments with vibration above 5 g, while the Tiger Eye design maintains reliable electrical continuity. The discrete wire termination also makes it ideal for replacing failed individual wires in field-maintainable systems without replacing the entire harness.
