What are the key features of STMM-123-02-S-D-SM?
- 2.00 mm pitch dual-row shrouded design provides polarization and mismating protection for cable-to-board connections
- Surface mount (SM) termination enables automated reflow soldering for high-volume PCB assembly
- 46-position dual-row configuration delivers high signal density in a compact 2.00 mm pitch footprint
What is STMM-123-02-S-D-SM used for?
The STMM-123-02-S-D-SM is suited for wire-to-board connections in industrial control panels, medical devices, and portable electronics requiring a reliable 2.00 mm pitch interface with cable mate assemblies. Its shrouded body prevents accidental mismating during field assembly and servicing, reducing the risk of system errors. The surface mount termination integrates into standard reflow soldering processes, supporting automated PCB production.

Frequently Asked Questions
What pitch does the STMM-123-02-S-D-SM use, and how does that compare to standard 2.54 mm pitch connectors?
The STMM-123-02-S-D-SM uses a 2.00 mm pitch, which is tighter than the traditional 0.100 inch (2.54 mm) standard. This smaller pitch saves roughly 21% of connector length per position, enabling more compact PCB designs while still accommodating cables with 2.00 mm spaced terminations commonly used in portable and consumer electronic assemblies.
How does the shrouded housing on the STMM-123-02-S-D-SM protect cable assemblies during mating?
The shroud on the STMM-123-02-S-D-SM physically guides the mating cable connector into the correct orientation, preventing insertion of the cable at an offset or reversed position. This polarization feature is critical in field-serviced equipment where technicians may work in confined spaces, reducing damage-causing mismating events and protecting 46 signal lines simultaneously.
Is the STMM-123-02-S-D-SM compatible with standard reflow soldering, and what termination style does it use?
Yes, the -SM suffix indicates a surface mount termination style, making the STMM-123-02-S-D-SM fully compatible with standard lead-free reflow soldering at peak temperatures up to 260°C. The SMT pads eliminate the need for through-hole drilling, reducing PCB fabrication cost and enabling thinner board constructions with dual-side component placement.
