What are the key features of STMM-114-02-G-D-SM?
- 28-pin dual-row 2.00 mm pitch shrouded housing prevents mis-mating and mechanically keys cable assemblies in high-pin-count wire-to-board interfaces
- Gold (Au) over nickel (Ni) contact finish provides low and stable contact resistance over 500+ mating cycles in harsh humidity environments
- 1.345 inch body length with rectangular square-pin contacts supports dense 28-signal cable harness routing in industrial automation and medical device boards
What is STMM-114-02-G-D-SM used for?
STMM-114-02-G-D-SM is used in industrial control panels, medical instrument sub-assemblies, and robotic joint controllers where a 28-wire harness must reliably connect to a PCB through a keyed 2.00 mm pitch shrouded header. Its gold-over-nickel contact finish suits applications requiring low contact resistance below 20 mΩ and extended mating life across repeated field maintenance cycles. Embedded compute boards in defense and aerospace applications also specify this connector family for its positive latch, compact 2.00 mm pitch, and corrosion-resistant gold termination.

Frequently Asked Questions
How many pins does STMM-114-02-G-D-SM have, and how is the dual-row layout arranged?
STMM-114-02-G-D-SM is a 28-pin connector arranged in 2 rows of 14 on a 2.00 mm pitch within a 1.345 inch body. The dual-row rectangular pattern allows 28 independent signals to cross the wire-to-board boundary in a single connector footprint, reducing the PCB area and cable routing complexity compared to two separate 14-pin connectors occupying separate board locations.
Why is the gold contact finish on STMM-114-02-G-D-SM beneficial compared to tin-finished alternatives?
Gold (Au) over nickel (Ni) finish maintains contact resistance typically below 20 mΩ after 500 or more mating cycles, whereas tin contacts can develop 50–100 mΩ fretting corrosion resistance after 200 cycles in humid or vibration-prone environments. For medical devices and test equipment where signal integrity on low-level analog lines must be preserved over a 10-year service life, the gold finish prevents the oxidation and fretting failures that degrade tin contacts.
In which field-replaceable or serviceable equipment applications does STMM-114-02-G-D-SM excel?
STMM-114-02-G-D-SM excels in field-serviceable robotics joints, industrial valve actuators, and medical imaging sub-assemblies where technicians must disconnect and reconnect cable harnesses during preventive maintenance every 6 to 12 months. The shrouded 2.00 mm pitch housing guides the cable mate onto the header without visual inspection, and the gold contacts sustain reliable performance across 25 or more field-service mating cycles without measurable resistance increase.
How does STMM-114-02-G-D-SM's 2.00 mm pitch compare to 2.54 mm pitch connectors in PCB layout density?
At 2.00 mm pitch, STMM-114-02-G-D-SM's 1.345 inch (34.2 mm) body is approximately 20% shorter than a 2.54 mm pitch 28-pin dual-row header, which would occupy about 42 mm in length. This 8 mm space saving is significant on boards with widths between 30 mm and 60 mm, freeing routing channels and component keep-out zones that a standard 0.1 inch pitch connector would block.
