Key Features
- 30-position dual-row 2.00 mm pitch shrouded SMT terminal strip with mechanical keying (K) to ensure correct cable mate polarity and prevent mis-mating
- Tin (Sn) over Nickel (Ni) barrier contact termination compatible with standard lead-free reflow soldering profiles for RoHS-compliant manufacturing
- Compact body of 1.413 inch length and 0.237 inch breadth enables high-density board layouts in industrial control and instrumentation PCB assemblies
Applications
The STMM-115-02-L-D-SM-K-TR serves as a compact 30-pin polarized cable-to-board connector in industrial automation controllers, data acquisition systems, and medical instrumentation. The shrouded keyed design prevents incorrect cable mate insertion, protecting sensitive circuitry in multi-connector field-service environments. Tape-and-reel SMT packaging supports automated pick-and-place assembly for high-volume production runs.

Frequently Asked Questions
What are the body dimensions of the STMM-115-02-L-D-SM-K-TR and how many positions does it have?
The STMM-115-02-L-D-SM-K-TR has a body length of 1.413 inches, breadth of 0.237 inch, and depth of 0.240 inch, housing 30 dual-row positions at 2.00 mm pitch. This compact footprint suits high-density SMT PCBs in industrial data acquisition and instrumentation equipment.
What contact termination finish does the STMM-115-02-L-D-SM-K-TR use and is it compatible with lead-free reflow?
The STMM-115-02-L-D-SM-K-TR uses Tin (Sn) with a Nickel (Ni) barrier on the contact termination, which is fully compatible with lead-free reflow soldering at standard peak temperatures of 260°C. This RoHS-compliant finish suits modern SMT production lines and meets industry environmental regulations.
How does the keying on the STMM-115-02-L-D-SM-K-TR prevent cable assembly errors in field maintenance?
The K-suffix mechanical keying uses an asymmetric shroud feature that blocks mating unless the 30-pin cable connector is correctly oriented at the 2.00 mm pitch interface. This prevents reverse-polarity connections during field cable replacement, protecting industrial control circuitry from damage.
When would a designer select the 30-position STMM-115 over the 46-position STMM-123 variant for a compact I/O module?
A designer would select the STMM-115-02-L-D-SM-K-TR (30 positions, 1.413-inch body) over the 46-position STMM-123 when the I/O signal count is 30 pins or fewer and board space is limited, saving approximately 32% in connector body length while maintaining the same 2.00 mm pitch and SMT keyed shroud design.
