What are the key features of STMM-123-02-F-D-SM-K-TR?
- 46-position dual-row layout on 2.00 mm pitch with a polarized shroud prevents misalignment and incorrect cable insertion, protecting signal integrity in wire-to-board cable-mate assemblies
- Surface-mount (SM) termination enables automated SMT assembly on standard reflow lines without through-hole drilling, reducing PCB layer-stack complexity and manufacturing cost
- Tape-and-reel (TR) packaging supports high-volume automated pick-and-place assembly with standard feeder pitch, minimizing setup time for production runs of 1000 or more units
What is STMM-123-02-F-D-SM-K-TR used for?
The STMM-123-02-F-D-SM-K-TR is designed for cable-to-board interconnect in embedded computing, industrial automation, and robotics applications where a high pin count at 2.00 mm pitch must be reliably mated and demated in the field. Its shrouded dual-row format on a 2A-per-pin rated contact system supports mixed signal and auxiliary power wiring harnesses in servo drives, motor controllers, and PLC expansion modules. The surface-mount tails and tape-and-reel packaging make it equally suitable for high-volume consumer and industrial PCB assembly lines using standard SMT reflow processes.

Frequently Asked Questions
How many contacts does the STMM-123-02-F-D-SM-K-TR connector provide and at what pitch?
The STMM-123-02-F-D-SM-K-TR is a 46-position dual-row connector, giving 46 total contacts arranged in 2 rows on a 2.00 mm pitch. At 2.00 mm center-to-center spacing, the connector body is approximately 24 mm long, making it a mid-density choice that sits between the compact 1.27 mm pitch and the traditional 2.54 mm pitch formats, and it mates with SAMTEC's SFSD or equivalent dual-row 2.00 mm pitch cable-end housings.
What is the current rating per pin for STMM-123-02-F-D-SM-K-TR and what wire gauges does its cable mate support?
Each contact in the STMM-123-02-F-D-SM-K-TR is rated at 2A per pin at room temperature, allowing up to 92A aggregate across all 46 contacts when used for distributed power. The cable-mate housings for 2.00 mm pitch SAMTEC terminal strips typically accept 22 to 28 AWG conductors (cross-sections of 0.08 mm² to 0.35 mm²), covering both low-current signal wiring and higher-current auxiliary power feeds common in motor control and automation harnesses.
Why does the shroud on STMM-123-02-F-D-SM-K-TR matter for field-installed cable-to-board assemblies?
The polarized shroud on the STMM-123-02-F-D-SM-K-TR acts as a keying and alignment guide, ensuring the mating cable connector can only be inserted in the correct orientation on a 2.00 mm pitch. Without a shroud, a dual-row connector with 46 positions can be misaligned by 1 or 2 positions, causing shorts or signal inversion that can damage ICs or produce incorrect logic states. The shroud is especially valuable in field-service environments where technicians may swap cables under poor lighting or time pressure.
How does tape-and-reel packaging of STMM-123-02-F-D-SM-K-TR benefit high-volume PCB production?
The TR (tape-and-reel) suffix means STMM-123-02-F-D-SM-K-TR ships on a standard embossed carrier tape and reel compatible with SMT pick-and-place feeders at the standard 2.00 mm pitch reel format. This eliminates manual tray-loading and cut-tape handling, reducing feeder changeover time from minutes to seconds per batch and achieving placement throughput of 3000 to 8000 components per hour on modern placement machines, which is critical for production runs of 5000 or more boards per week.
