What are the key features of STMM-123-02-H-D-SM-K-TR?
- 2.00 mm pitch dual-row shrouded terminal strip with 46 total positions (23 per row) offering high-density wire-to-board interconnect in a compact SMT footprint
- Keyed shroud (K suffix) prevents incorrect cable-mate mating orientation, reducing assembly errors in production environments
- Tape-and-reel (TR) packaging supports automated pick-and-place SMT assembly for high-volume manufacturing with consistent placement accuracy
What is STMM-123-02-H-D-SM-K-TR used for?
The STMM-123-02-H-D-SM-K-TR is used in embedded computing modules, industrial automation controllers, and telecommunications equipment where a 2.00 mm pitch dual-row cable-mate connector provides high-density, polarized wire-to-board signal connections. Its surface mount SMT tails integrate seamlessly with standard PCB reflow processes, eliminating through-hole drilling and reducing manufacturing cycle time. The keyed shroud ensures correct cable-mate orientation during field installation and maintenance, minimizing the risk of connector damage in multi-connector panel systems.

Frequently Asked Questions
How many positions does the STMM-123-02-H-D-SM-K-TR provide and what is its contact pitch?
The STMM-123-02-H-D-SM-K-TR is a dual-row connector with 23 positions per row totaling 46 contacts at a 2.00 mm pitch, providing a high-density wire-to-board interface in an SMT shrouded terminal strip configuration for industrial and embedded computing applications.
What does the K suffix in STMM-123-02-H-D-SM-K-TR indicate and why does it matter for system assembly?
The K suffix designates a keyed shroud that physically prevents incorrect mating orientation when connecting cable assemblies. This polarization feature is critical in multi-connector panel designs with 46-position 2.00 mm pitch connectors, reducing field wiring errors and preventing damage to populated PCBs during maintenance or system integration.
How does the SMT mounting of STMM-123-02-H-D-SM-K-TR benefit high-volume PCB production compared to through-hole alternatives?
The surface mount SMT tails of the STMM-123-02-H-D-SM-K-TR eliminate the need for through-hole drilling and wave soldering, reducing PCB manufacturing steps for a 46-position 2.00 mm pitch connector. Combined with tape-and-reel packaging, this enables fully automated reflow assembly at rates exceeding 1000 units per hour on standard SMT production lines.
