Key Features
- 2.00 mm pitch 16-position dual-row shrouded design provides mechanical key alignment and prevents mis-mating in cable assembly applications
- Gold (30 µin) over nickel (50 µin) contact finish ensures reliable low-resistance mating contact in harsh or high-cycle environments
- Phosphor bronze contact material delivers superior spring retention force for consistent 2 A per contact rating across thousands of mating cycles
- Surface mount termination simplifies PCB assembly by eliminating through-hole drilling while maintaining robust board attachment
Applications
The STMM-108-02-S-D-SM is used in board-stacking and cable-to-board interconnect applications within industrial automation, medical device panels, and embedded computing modules where a 2.00 mm pitch provides a balance of compact size and ease of assembly. The shrouded housing guides the mating cable connector and prevents accidental pin-to-pin shorting during field replacement of daughterboards or harnesses. Its surface mount pads allow integration into mixed SMT assembly lines without requiring wave solder or hand soldering for connector attachment.

Frequently Asked Questions
What contact finish does the STMM-108-02-S-D-SM use, and how does it perform in high-cycle mating applications?
The STMM-108-02-S-D-SM uses gold (30 µin) over nickel (50 µin) on mating contacts and matte tin over nickel on the termination side. The 30 µin gold mating finish supports a mating cycle life of at least 500 cycles while keeping contact resistance below 20 mΩ, making it suitable for field-replaceable module and cable assembly designs in industrial equipment.
How does the 2.00 mm pitch on STMM-108-02-S-D-SM compare to 2.54 mm pitch connectors for dense PCB layouts?
At 2.00 mm pitch, the STMM-108-02-S-D-SM accommodates 16 positions in a dual-row footprint approximately 16 mm long, roughly 20% shorter than a 2.54 mm pitch equivalent accommodating the same contact count. This space saving is significant on boards where connector row length directly competes with other components, especially in half-rack or quarter-brick power module designs where every millimeter counts.
Can STMM-108-02-S-D-SM be used for board stacking in addition to cable-mate applications?
Yes, the STMM-108-02-S-D-SM is designed for both cable-mate and board stacking configurations within the SAMTEC STMM/STMM family. The 2.00 mm pitch and dual-row 16-position layout accept the corresponding SAMTEC STM or TFM series terminal strip headers with stacking heights configurable from approximately 4 mm to 15 mm depending on the mating header pin length selected.
What is the current rating per contact for STMM-108-02-S-D-SM and how does phosphor bronze affect that specification?
Each contact in the STMM-108-02-S-D-SM is rated at 2 A continuous, supported by phosphor bronze as the contact material — an alloy chosen for its high elastic modulus (approximately 110 GPa) and ability to maintain spring force over temperature excursions from -40°C to +105°C. This material choice helps sustain consistent contact normal force above 100 grams throughout the product's operating life, preventing intermittent connections under thermal cycling.
