What are the key features of STMM-112-02-S-D-SM?
- 2.00 mm pitch dual-row shrouded terminal strip provides 24 positions for dense board-to-board signal routing
- Gold (30 µin) over nickel (50 µin) mating contact finish ensures low contact resistance and long mating cycle life
- Phosphor bronze contact material delivers consistent spring force and reliable electrical performance across thermal cycling
What is STMM-112-02-S-D-SM used for?
The STMM-112-02-S-D-SM is used in board stacking and cable-mate applications within industrial control panels, embedded computing modules, and test instrumentation requiring 24 low-profile signal connections at 2.00 mm pitch. Its shrouded design prevents mis-mating and protects contacts from contamination in automated assembly and field-service environments. The gold-over-nickel contact finish ensures consistent conductivity through thousands of mating cycles in high-reliability systems.

Frequently Asked Questions
What contact pitch and position count does the STMM-112-02-S-D-SM offer for board stacking applications?
The STMM-112-02-S-D-SM features a 2.00 mm pitch with 24 positions arranged in a dual-row configuration. This 2.00 mm spacing is wider than 1.27 mm alternatives, offering improved mechanical retention and easier routing of signal traces between stacked PCBs in industrial and embedded computing designs.
How do the gold-over-nickel mating contacts in the STMM-112-02-S-D-SM compare to tin-finished contacts for high-cycle applications?
The STMM-112-02-S-D-SM uses 30 µin gold over 50 µin nickel on mating contacts, which provides significantly lower and more stable contact resistance than matte tin finishes over hundreds to thousands of mating cycles. Gold's corrosion resistance also eliminates fretting issues that degrade tin contacts in vibration-prone environments, making it preferable for industrial and instrumentation applications.
Why is the shrouded design of the STMM-112-02-S-D-SM important for cable-mate configurations in field-serviced equipment?
The shroud on the STMM-112-02-S-D-SM mechanically guides the mating cable connector into the correct orientation, preventing pin damage and mis-mating across all 24 positions. In field-serviced equipment such as industrial I/O modules or medical devices, this keying feature reduces assembly errors and connector damage during maintenance procedures performed without PCB inspection.
What is the typical factory lead time for the STMM-112-02-S-D-SM, and how should this factor into production planning?
The STMM-112-02-S-D-SM has a factory lead time of approximately 2 weeks and 6 days, which is relatively short for precision board stacking connectors. Procurement teams should maintain a buffer stock of 2 to 3 weeks of production demand to absorb any supplier schedule variations without disrupting assembly line operations.
