Frequently Asked Questions
What contact finish does the STMM-125-02-G-D-SM use and why does it matter?
The STMM-125-02-G-D-SM features gold (20 µin) over nickel (50 µin) plating on both mating and termination contacts. Gold plating minimizes oxidation and ensures low contact resistance across repeated mating cycles, making it critical for high-reliability board stacking applications in industrial and instrumentation environments.
How many positions does the STMM-125-02-G-D-SM support and what pitch is used?
The STMM-125-02-G-D-SM provides 50 positions in a dual-row (25+25) configuration at a 2.00 mm pitch. This combination supports high pin-count cable-to-board connections within a compact 2.212 inch body length, suited for density-critical embedded and communications board interconnects.
When is the STMM-125-02-G-D-SM a better choice than 2.54 mm pitch connectors for new designs?
The STMM-125-02-G-D-SM's 2.00 mm pitch reduces the total connector footprint compared to standard 2.54 mm alternatives by approximately 21% per row, allowing more circuit components in a fixed board area. This is advantageous in compact embedded modules, ruggedized handhelds, and medical devices where PCB real estate is at a premium.
