Frequently Asked Questions
How many positions does the STMM-117-02-L-D-SM connector have and how are they arranged?
The STMM-117-02-L-D-SM features 34 positions arranged in a dual-row configuration with 2.00 mm pitch. This rectangular contact pattern provides 17 pins per row, enabling high-density signal routing in compact board stacking applications while maintaining reliable electrical connections.
What contact finish is used on the STMM-117-02-L-D-SM and why does it matter for connector reliability?
The STMM-117-02-L-D-SM uses gold (10 µin) over nickel (50 µin) for the mating contacts. Gold plating provides excellent corrosion resistance and low contact resistance, ensuring reliable signal integrity even after thousands of mating cycles in industrial and communications applications.
Which PCB assembly methods are compatible with the STMM-117-02-L-D-SM termination style?
The STMM-117-02-L-D-SM uses a surface mount (SM) termination style with tin/nickel barrier finish on termination contacts. This makes it compatible with standard SMT reflow soldering processes at typical reflow temperatures around 260°C, enabling automated board assembly for high-volume production.
In which embedded computing or industrial applications is the STMM-117-02-L-D-SM most commonly used?
This connector is commonly used in embedded computing modules, industrial control systems, and communications backplanes requiring 2.00 mm pitch board stacking. Its 34-position dual-row layout supports up to 34 simultaneous signal or power connections, making it suitable for data acquisition systems and module-to-backplane interfaces.
