Key Features
- 30-position dual-row shrouded terminal strip at 2.00 mm pitch with keyed polarity protection for error-proof cable mating
- 10 micro-inch gold over 50 micro-inch nickel mating contact finish for ultra-low contact resistance and long mating cycle life
- Phosphor bronze contact material provides high spring force retention and reliable electrical engagement in cable-mate board stacking applications
Applications
The STMM-115-02-L-D-SM is designed for cable-mate board stacking connections in industrial control systems, embedded computing modules, and telecommunications equipment where reliable cable-to-board signal routing at 2.00 mm pitch is required. Its shrouded housing with 30 dual-row positions prevents mis-mating and protects contacts from mechanical damage during field assembly and maintenance. The gold-over-nickel contact finish with phosphor bronze spring contacts ensures consistent low-resistance connections across hundreds of mating cycles in demanding operating environments.

Frequently Asked Questions
What contact material and plating does the STMM-115-02-L-D-SM use, and how many mating cycles does that support?
The STMM-115-02-L-D-SM uses phosphor bronze contacts with 10 micro-inch gold over 50 micro-inch nickel mating finish. This gold plating provides contact resistance below 15 milliohms and supports a rated mating cycle life of at least 30 cycles for board stacking and cable-mate applications, making it reliable for field-serviceable modules and test equipment requiring repeated connect-disconnect cycles.
How does the 2.00 mm pitch and shrouded housing of the STMM-115-02-L-D-SM benefit cable assembly and field installation?
The 2.00 mm pitch on the STMM-115-02-L-D-SM provides a good balance between contact density and handling ease for field cable assembly, accepting 30 dual-row positions in a compact body of 0.257" breadth. The shrouded polarity-keyed housing ensures cables can only be inserted in the correct orientation, preventing mis-wiring errors that could damage equipment during field installation or PCB bring-up in industrial control and embedded computing applications.
In what ways does the STMM-115-02-L-D-SM differ from non-shrouded 2.00 mm terminal strips for high-reliability cable-mate applications?
Unlike open-pin terminal strips at 2.00 mm pitch, the STMM-115-02-L-D-SM features a shroud that fully surrounds and protects all 30 dual-row contacts from lateral accidental contact, ESD, and mechanical damage during cable insertion. The shroud also acts as a polarization key, reducing mis-mating risk to near zero compared to open-pin alternatives. In high-reliability applications like industrial robot controllers or medical device backplanes, this physical protection prevents costly connector damage during repeated maintenance cycles.
