What are the key features of STMM-122-02-T-D-SM?
- 44-position dual-row shrouded board stacking terminal strip at 2.00 mm pitch with 0.257 inch body breadth for high-density signal routing
- Phosphor bronze contacts with matte tin over nickel (50 µin) mating finish provide reliable electrical performance across hundreds of mating cycles
- Matte tin (Sn) over nickel (Ni) barrier termination ensures robust solder joint integrity compatible with standard lead-free reflow processes up to 260°C
What is STMM-122-02-T-D-SM used for?
The STMM-122-02-T-D-SM is used in multi-board stacking systems, cable harness interconnect assemblies, and industrial embedded platforms where a 44-position dual-row shrouded 2.00 mm pitch terminal strip with board stacking capability is required. Its phosphor bronze contacts with matte tin mating plating provide stable low-resistance connections in telecom shelf boards, industrial I/O expansion modules, and backplane cable harness assemblies. The SMD termination enables automated PCB assembly in high-volume production environments.

Frequently Asked Questions
What is the position count and body size of the STMM-122-02-T-D-SM?
The STMM-122-02-T-D-SM is a 44-position dual-row shrouded terminal strip at 2.00 mm pitch with a body breadth of 0.257 inch and body depth of 0.190 inch, accommodating 22 contacts per row for high-density board stacking and cable mate interconnect in industrial and telecom applications.
What contact material and plating does the STMM-122-02-T-D-SM use?
The STMM-122-02-T-D-SM uses phosphor bronze contacts with matte tin over nickel (50 µin) mating plating and matte tin (Sn) over nickel (Ni) barrier termination. Phosphor bronze provides high spring force for reliable contact retention, while the 50 µin tin mating finish maintains low contact resistance below 20 mΩ across hundreds of mating cycles.
Which board stacking and cable harness applications use the STMM-122-02-T-D-SM?
Industrial PLC expansion backplanes, telecom sub-rack board interconnects, server management controller daughter boards, and laboratory instrumentation modular assemblies all use the STMM-122-02-T-D-SM where 44 signals at 2.00 mm pitch must be routed across stacked PCBs or flexible cable harnesses within enclosures with board separations of 10 mm to 50 mm.
How does the dual-row shrouded design of STMM-122-02-T-D-SM improve assembly reliability versus open-pin headers?
The shrouded housing guides mating cable connectors into correct alignment across all 44 positions simultaneously, preventing bent pins during assembly and ensuring each of the 44 contacts seats fully. Compared to open-pin headers of equivalent 2.00 mm pitch, the shroud reduces field assembly misalignment errors and maintains contact normal force within the 0.3 N to 1.0 N range specified for matte tin contacts.
