Key Features
- 2.00 mm pitch dual-row shrouded terminal strip with 4 positions for compact board-to-cable signal connections
- Gold (Au) contact finish for superior corrosion resistance and lower contact resistance over extended service life
- Surface-mount (SM) termination enables automated SMT reflow assembly with consistent coplanarity across PCB batches
- Keyed (K) shroud polarization prevents mis-mating during cable assembly and field maintenance operations
Applications
The STMM-102-02-G-D-SM-K-TR suits signal interconnect applications in industrial control panels, embedded computing modules, and telecommunications equipment requiring a compact 2.00 mm pitch connector with gold-plated contacts. Its 4-position dual-row layout and surface-mount footprint facilitate automated PCB assembly while the keyed shroud ensures correct cable orientation during installation. This part is well suited for low-to-medium signal current routing in medical instrumentation and data acquisition systems.

Frequently Asked Questions
How many positions does the STMM-102-02-G-D-SM-K-TR provide, and what is its pitch?
The STMM-102-02-G-D-SM-K-TR has 4 positions arranged in a dual-row configuration at a 2.00 mm pitch, providing a very compact footprint suitable for high-density PCB layouts in embedded and telecommunications applications.
What advantage does the gold contact finish in STMM-102-02-G-D-SM-K-TR offer over tin-finished alternatives?
Gold (Au) plating on the contacts delivers exceptionally low and stable contact resistance — typically below 30 mΩ — compared to standard tin-plated connectors, making the STMM-102-02-G-D-SM-K-TR more reliable for low-voltage signal circuits and applications requiring thousands of mating cycles without degradation.
Which assembly processes are compatible with the STMM-102-02-G-D-SM-K-TR?
As a surface-mount (SM) device, the STMM-102-02-G-D-SM-K-TR is designed for standard reflow soldering at typical SMT peak temperatures of 260°C, fully compatible with automated pick-and-place equipment for high-throughput PCB production.
When should a designer choose STMM-102-02-G-D-SM-K-TR over STMM-104-02-L-D-SM-K-TR?
Choose the STMM-102-02-G-D-SM-K-TR when the design requires only 4 signal positions instead of 8, or when low contact resistance is critical — its gold finish keeps resistance below 30 mΩ versus the tin-nickel finish on the 104 variant — saving board space while maintaining high signal integrity.
