Frequently Asked Questions
How many positions does the STMM-114-02-F-D-SM have and what is its contact pitch?
The STMM-114-02-F-D-SM features 28 positions arranged in 2 rows of 14 contacts each, with a 2.00 mm pitch between adjacent contacts. This configuration allows routing 28 signal channels in a compact footprint suitable for dense cable-to-board interconnect designs.
What contact material and plating does the STMM-114-02-F-D-SM use, and how does it affect mating reliability?
The STMM-114-02-F-D-SM uses phosphor bronze contacts with gold (AU) over nickel (NI) plating on the mating surface. Gold plating ensures low contact resistance typically below 20 mΩ and resistance to oxidation, supporting reliable electrical connections across hundreds of mating cycles in industrial or instrumentation applications.
For a compact industrial control module, how does the 2.00 mm pitch STMM-114-02-F-D-SM compare to a 2.54 mm pitch alternative?
At 2.00 mm pitch versus 2.54 mm, the STMM-114-02-F-D-SM reduces the connector row length by approximately 21% for the same pin count, freeing valuable PCB real estate in space-constrained designs. The smaller pitch also corresponds to thinner cable assemblies, which can reduce overall wiring harness bulk in enclosed systems by 15 to 25% depending on cable gauge.
Is the STMM-114-02-F-D-SM suitable for high-cycle mating applications, and what is the expected cycle life?
SAMTEC STMM series connectors are rated for a minimum of 30 mating cycles, which is standard for board-to-cable connectors used in field-serviceable equipment. The gold-plated contacts help maintain consistent contact resistance below 30 mΩ throughout the rated cycle life, making the connector appropriate for maintenance panels and serviceable embedded modules.
