Key Features
- 2.00 mm pitch dual-row shrouded terminal strip with 8 positions for compact board-to-cable connections
- Tin (Sn) over Nickel (Ni) barrier contact finish for excellent corrosion resistance and solderability
- Surface-mount (SM) termination style enabling automated PCB assembly with consistent coplanarity
- Keyed (K) shroud polarity feature prevents mis-mating during cable assembly installation
Applications
The STMM-104-02-L-D-SM-K-TR is widely used in industrial control systems, embedded computing boards, and test and measurement equipment where reliable board-to-cable signal connections at 2.00 mm pitch are required. Its keyed shroud and surface-mount footprint make it well suited for automated assembly environments in telecommunications and data acquisition hardware. The dual-row 8-position layout supports moderate pin-count interconnects in space-constrained PCB designs.

Frequently Asked Questions
What pitch and row configuration does the STMM-104-02-L-D-SM-K-TR use?
The STMM-104-02-L-D-SM-K-TR uses a 2.00 mm pitch dual-row layout with 8 total positions (4 per row), providing a compact footprint of approximately 0.555 inch body length for board-to-cable signal routing on surface-mount PCBs.
What contact finish does the STMM-104-02-L-D-SM-K-TR use, and how does it benefit reliability?
The connector uses a Tin (Sn) contact finish over a Nickel (Ni) barrier layer. This combination delivers corrosion resistance across operating temperatures and maintains low contact resistance over thousands of mating cycles, extending service life in industrial environments.
Which PCB assembly processes are compatible with the STMM-104-02-L-D-SM-K-TR?
As a surface-mount (SM) termination device, the STMM-104-02-L-D-SM-K-TR is fully compatible with standard SMT reflow soldering processes, allowing integration into automated pick-and-place assembly lines with body dimensions of 0.555 inch x 0.24 inch x 0.237 inch.
How does the keyed shroud on the STMM-104-02-L-D-SM-K-TR prevent mis-mating?
The 'K' keying feature adds a mechanical polarization element to the 2.00 mm shrouded housing that physically blocks incorrect cable-mate insertion, reducing assembly errors and protecting the 8 male square-pin contacts from damage during field installation or maintenance.
