Frequently Asked Questions
What pitch and position count does S2M-125-01-S-D provide for discrete wire harness connections?
The S2M-125-01-S-D offers 50 positions at a 2.00 mm pitch in a dual-row female socket configuration with a 1.982-inch body length. This 2.00 mm pitch is well suited for discrete wire termination where individual wires need to be routed from a PCB to an external harness, providing ample contact spacing for reliable hand or machine crimping.
Why is the gold termination finish on S2M-125-01-S-D important for high-reliability applications?
The gold (Au) termination finish on the S2M-125-01-S-D provides excellent corrosion resistance and maintains low contact resistance over time, even in environments with elevated humidity, temperature cycling from -55°C to +125°C, or exposure to mild chemical contaminants. This makes it suitable for military, aerospace, and medical applications where connector failure is not acceptable.
In what system architectures does S2M-125-01-S-D function as a board stacking connector?
The S2M-125-01-S-D serves as a board stacking connector in modular system architectures where separate PCBs or sub-assemblies are interconnected via wire harnesses rather than rigid board-to-board stacking. With 50 positions at 2.00 mm pitch, it can carry up to 50 independent signal or power channels, making it suitable for industrial control backplanes, medical instrument modules, and communications chassis assemblies.
