What are the key features of STMM-124-02-H-D-SM-K-TR?
- 48-position dual-row 2.00 mm pitch shrouded cable-mate terminal strip with keyed polarisation housing prevents mismating in high-density wire-to-board assemblies
- High-profile (H) shroud variant provides additional mating depth and mechanical retention compared to standard-profile versions, suited for vibration-prone industrial environments
- Tape-and-reel (TR) packaging with SMT termination enables fully automated pick-and-place assembly, reducing per-unit handling cost in production runs of thousands of units
What is STMM-124-02-H-D-SM-K-TR used for?
The STMM-124-02-H-D-SM-K-TR is designed for wire-to-board cable harness connections in industrial automation, robotics, and embedded control panels where 48 lines must interface reliably at 2.00 mm pitch. The high-profile keyed shroud protects contacts from accidental mismating and physical damage during cable installation in the field. Its SMT footprint and tape-and-reel packaging make it straightforward to integrate into automated PCB assembly lines for high-volume production.

Frequently Asked Questions
How does the high-profile (H) shroud variant STMM-124-02-H-D-SM-K-TR differ from the standard-profile STMM-124-02-L-D-SM-K-TR in vibration-prone installations?
The high-profile shroud provides deeper mating engagement of approximately 4 mm to 5 mm versus roughly 2 mm on the low-profile L variant, giving the mating cable-side plug more mechanical grip during vibration and shock events common in motor drives, conveyor controllers, and mobile industrial equipment operating to IEC 60068 vibration specifications. This extra retention reduces risk of accidental unmating and signal interruption.
What is the contact pitch and pin count of the STMM-124-02-H-D-SM-K-TR, and what harness wire gauges are compatible?
The connector uses 2.00 mm pitch with 48 positions in a dual-row (2 x 24) arrangement. This pitch accommodates cable-side crimp contacts for wire gauges from 26 AWG to 28 AWG, carrying signal currents up to about 1 A per contact and low-power supply currents, covering typical requirements of digital I/O lines, analogue sensor signals, and 3.3 V to 5 V logic buses in industrial control harnesses.
Why does the keyed housing (K option) on the STMM-124-02-H-D-SM-K-TR reduce assembly errors in multi-connector PCBs?
On boards with multiple identical-looking 2.00 mm pitch connectors placed side by side, the K keying polarisation notch ensures the cable plug can only mate with its designated receptacle, preventing cross-connection of signal buses during field installation or service. This is critical when neighbouring connectors carry power rails at different voltages such as 5 V and 12 V, where a swap would immediately damage circuits and create safety risks.
