Key Features
- 2.00 mm pitch dual-row shrouded housing with 24 contacts provides keyed, high-density cable-to-board connectivity in a compact footprint
- Gold (Au) over nickel (Ni) contact finish ensures low contact resistance and corrosion resistance for reliable signal integrity over thousands of mating cycles
- Surface mount (SM) termination enables direct SMT reflow assembly, eliminating through-hole drilling for space-efficient PCB integration
Applications
The STMM-112-02-H-D-SM is designed for cable-to-board interconnection in medical devices, industrial instrumentation, and embedded computing systems where a 2.00 mm pitch, 24-position shrouded connector with gold contacts is required. Its SMT termination and shrouded housing make it suitable for applications demanding both automated PCB assembly and reliable, polarized cable mate connections in vibration-prone environments.

Frequently Asked Questions
What pitch and contact count does the STMM-112-02-H-D-SM offer, and how are the contacts finished?
The STMM-112-02-H-D-SM has 24 contacts arranged in 2 rows at a 2.00 mm pitch, with a gold (Au) over nickel (Ni) contact finish. This combination provides low contact resistance and excellent corrosion resistance, making it suitable for signal-level connections requiring reliable mating performance over extended service life.
How does the shrouded housing of STMM-112-02-H-D-SM improve reliability in cable-to-board connections?
The shrouded housing of the STMM-112-02-H-D-SM provides mechanical keying to prevent mis-mating and protects the 24 square-pin contacts from accidental damage during cable assembly and field servicing. This feature is especially valuable in medical and industrial equipment where connector mis-insertion at 2.00 mm pitch could damage fine-pitch contacts or cause signal faults.
For a vibration-prone industrial enclosure, why would a designer choose STMM-112-02-H-D-SM over an unshrouded header?
In applications exposed to mechanical vibration, such as factory automation controllers or mobile equipment, the shrouded housing of the STMM-112-02-H-D-SM retains the mating cable connector and prevents partial unmating that can cause intermittent contact at the 2.00 mm pitch interface. Combined with gold-over-nickel contacts and SMT mounting, it maintains signal integrity even under sustained vibration loads.
