Key Features
- 112-position dual-row shrouded terminal strip on a 2.00 mm pitch, delivering high signal density in a compact SMD footprint
- Shrouded housing with polarization prevents mis-mating of the cable connector, protecting all 112 signal contacts during field installation
- Surface-mount termination (SM) is compatible with standard reflow soldering processes for cost-effective high-volume PCB assembly
Applications
The STMM-112-02-TM.SM.LM-D-SM is used for high-density board-to-cable harness connections in embedded computing platforms, industrial automation controllers, and telecommunications rack equipment where 112 signals must route reliably through a single 2.00 mm pitch connector. Its surface-mount footprint and shrouded design reduce assembly errors and provide mechanical robustness in vibration-prone industrial environments.

Frequently Asked Questions
How many contacts does the STMM-112-02-TM.SM.LM-D-SM have, and how are they arranged?
The STMM-112-02-TM.SM.LM-D-SM contains 112 contacts in a dual-row configuration on a 2.00 mm pitch. This layout provides 56 contacts per row, enabling high-density board-to-cable signal routing while keeping the overall connector footprint compact enough for space-constrained PCB designs in embedded and industrial applications.
In an industrial automation controller with 100+ I/O signals, what advantage does the STMM-112-02-TM.SM.LM-D-SM's shroud provide?
The shrouded housing of the STMM-112-02-TM.SM.LM-D-SM physically guides and polarizes the mating cable connector across all 112 positions, preventing reverse insertion and accidental half-mating that could damage signal lines in an industrial automation controller. The shroud also protects contacts from dust and mechanical impact during routine maintenance cycles in factory environments rated up to 70°C.
Can the STMM-112-02-TM.SM.LM-D-SM be used in automated SMT assembly, and what termination style does it use?
Yes, the STMM-112-02-TM.SM.LM-D-SM uses a surface-mount (SM) termination style, making it fully compatible with automated pick-and-place equipment and standard reflow soldering at peak temperatures up to 260°C. This eliminates the need for through-hole wave soldering, allowing the 112-position connector to be populated on the same SMT line as other board-level components.
