- Surface-mount (SM) termination enables automated SMT reflow assembly at temperatures up to 260 °C for high-volume production
- 50-position dual-row layout with 25 contacts per row enables compact, high-density wire-to-board cable connections
Applications
The STMM-125-02-FM-D-SM is designed for wire-to-board cable interconnect applications in industrial control systems, telecom equipment, and embedded computing platforms where a polarized, shrouded 2.00 mm pitch connector prevents incorrect cable insertion. Its surface-mount termination style supports automated PCB assembly and its dual-row 50-position configuration allows routing of power, ground, and multiple signal lines through a single compact connector interface.

Frequently Asked Questions
How many positions does the STMM-125-02-FM-D-SM offer and how are they arranged?
The STMM-125-02-FM-D-SM provides 50 positions in a dual-row layout with 25 contacts per row on a 2.00 mm pitch. This configuration supports simultaneous routing of power lines and signal lines through one compact shrouded connector, reducing cable assembly complexity in industrial and embedded computing boards.
What mounting style does the STMM-125-02-FM-D-SM use and what reflow temperature does it support?
This SAMTEC terminal strip uses surface-mount (SM) termination, compatible with standard SMT reflow soldering at peak temperatures up to 260 °C per JEDEC J-STD-020. The SMT footprint integrates directly into automated PCB assembly lines, eliminating the need for hand-soldering through-hole terminals and improving manufacturing throughput.
What connector family mates with the STMM-125-02-FM-D-SM and why does the shroud matter for cable assembly?
The STMM series mates with SAMTEC SFMM-series cable-mate assemblies using discrete wire termination. The polarizing shroud enforces a single correct mating orientation, preventing reversed-cable insertions that could damage downstream circuits. Typical contact resistance is below 30 mΩ, and the shroud provides mechanical strain relief on the cable side reducing field failure rates.
