What are the key features of STMM-124-02-G-D-SM-K-TR?
- 124-position dual-row layout on 2.00 mm pitch enabling very high-density cable-to-board interconnects in a single compact connector
- Polarised shroud prevents incorrect mating orientation, eliminating mis-wiring errors in field assembly and rework
- Surface-mount tails in tape-and-reel format support fully automated SMT reflow soldering for high-volume manufacturing
What is STMM-124-02-G-D-SM-K-TR used for?
STMM-124-02-G-D-SM-K-TR is used in backplane and daughterboard assemblies where 124 signal or mixed-power lines must mate reliably in a 2.00 mm pitch footprint. Its shrouded dual-row SMT body suits data acquisition systems, test-and-measurement cards, and industrial control modules requiring robust board-to-cable connections with keying. The tape-and-reel packaging supports pick-and-place automation in high-volume electronic manufacturing.

Frequently Asked Questions
What configuration does STMM-124-02-G-D-SM-K-TR offer and what pitch does it use?
STMM-124-02-G-D-SM-K-TR is a 124-position dual-row shrouded terminal strip with 2.00 mm pitch, giving a total mating width of approximately 62 columns across 2 rows. The 2.00 mm pitch provides a balance between contact density and per-contact current capacity, typically rated at 3 A per contact for signal and low-power lines.
How does the shroud on STMM-124-02-G-D-SM-K-TR prevent wiring errors during cable assembly?
The polarised plastic shroud surrounding all 124 positions physically blocks reversed or offset mating, so technicians cannot plug the cable-mate connector in the wrong orientation. This keying feature is critical in 124-position assemblies where a single misaligned row could damage 62 signal pairs simultaneously during bring-up.
What are the PCB assembly requirements for STMM-124-02-G-D-SM-K-TR's SMT format?
The surface-mount tails require a standard SMT land pattern with 2.00 mm row spacing and 2.00 mm column pitch on a flat PCB pad array. Reflow soldering at peak temperatures up to 260°C (per IPC/JEDEC J-STD-020) is supported, and the tape-and-reel packaging enables automated pick-and-place for production volumes above 500 pieces per run.
When would a designer choose STMM-124-02-G-D-SM-K-TR over a 1.00 mm pitch alternative for a high-count signal bus?
At 2.00 mm pitch, STMM-124-02-G-D-SM-K-TR supports up to 3 A per contact versus roughly 1 A for a 1.00 mm pitch alternative, making it preferable when the 124-line bus includes mixed power and signal circuits. The wider pitch also improves solder joint robustness and makes hand-rework feasible for prototype boards, whereas 1.00 mm pitch connectors often require microscope-assisted soldering.
