Frequently Asked Questions
How many pins and what pitch does the STMM-120-02-G-D-SM have?
The STMM-120-02-G-D-SM is a 40-position dual-row board stacking connector with a 2 mm pitch. This combination makes it well suited for high-density mezzanine board interconnects in embedded computing and telecom applications requiring reliable signal integrity across stacked PCBs.
What contact finish is used in STMM-120-02-G-D-SM and why does it matter for mating cycles?
The connector uses Gold (20 µin) over Nickel (50 µin) on the mating surfaces. This gold-over-nickel finish provides excellent corrosion resistance and maintains low contact resistance across hundreds of mating cycles, making it reliable in high-reliability industrial and telecom board-stacking assemblies.
What is the lead time for STMM-120-02-G-D-SM and is it RoHS compliant?
The STMM-120-02-G-D-SM has a standard factory lead time of 1 week and is fully RoHS compliant. Phosphor bronze contacts and the 2 mm dual-row footprint support straightforward PCB integration, and stock availability enables fast procurement for production builds requiring this 40-pin stacking connector.
