Key Features
- 46 positions in dual-row 2.00 mm pitch shrouded SMT header for compact wire-to-board connectivity
- Shrouded housing providing polarized keyed mating to prevent connector mis-insertion in cable-mate assemblies
- Female (F) contact style with SMT termination enabling automated PCB assembly and reflow soldering
- 2.00 mm pitch reduces footprint compared to 2.54 mm headers while maintaining reliable crimped-wire cable mating
Applications
The STMM-123-02-F-D-SM is used in compact embedded system boards, robotics platforms, and industrial control units requiring keyed wire-to-board connections at 2.00 mm pitch with SMT mounting. Its shrouded housing prevents mis-mating in high-vibration environments such as motor drives and automation equipment. Consumer electronics, IoT gateways, and portable medical devices also use this terminal strip where a secure, polarized cable interface is needed in a space-constrained PCB layout.

Frequently Asked Questions
How many positions and what pitch does the STMM-123-02-F-D-SM provide for wire-to-board connections?
The STMM-123-02-F-D-SM offers 46 positions in 2 rows at 2.00 mm pitch, providing a more compact wire-to-board footprint than standard 2.54 mm connectors while accommodating cables with up to 46 individual wire terminations in a shrouded SMT header.
What does the shrouded housing on the STMM-123-02-F-D-SM protect against during field assembly?
The shrouded housing acts as a mechanical polarizing key that physically blocks incorrect cable orientation, preventing mis-insertion damage across the 46 positions at 2.00 mm pitch in industrial, robotics, and high-vibration applications where reliable mating is critical.
Is the STMM-123-02-F-D-SM compatible with automated SMT reflow assembly processes?
Yes, the SM (surface mount) termination style means the STMM-123-02-F-D-SM can be placed by pick-and-place machines and soldered in standard lead-free reflow ovens, making it efficient for high-volume PCB production of 46-position dual-row 2.00 mm pitch cable-mate headers.
In which embedded system designs is the 2.00 mm pitch of the STMM-123-02-F-D-SM preferred over a 2.54 mm header?
When PCB space is limited and the design requires 46 wire connections in a dual-row format, the 2.00 mm pitch saves approximately 21% of connector length compared to 2.54 mm alternatives, making it preferred in compact robotics controllers, portable industrial terminals, and space-constrained IoT edge devices.
