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.
