Frequently Asked Questions
What position count and pitch does STMM-123-02-TM.SM.LM-D-SM-K-TR offer for cable-to-board connections?
The STMM-123-02-TM.SM.LM-D-SM-K-TR provides 46 positions in a dual-row layout at 2.00mm pitch, giving a total signal capacity of 46 lines with a connector body approximately 47mm in length, suitable for high-density cable assemblies in industrial and embedded systems.
What do the TM, SM, and LM tail options mean on STMM-123-02-TM.SM.LM-D-SM-K-TR?
TM denotes through-mount tails soldered into PCB through-holes, SM indicates surface-mount tails for reflow attachment, and LM represents lead-mount tails for panel or chassis mounting. Having all 3 options on the same part lets engineers select the 2.00mm pitch connector for different PCB assembly methods without changing the mating interface.
How does the keyed shroud of STMM-123-02-TM.SM.LM-D-SM-K-TR prevent field wiring errors in 46-position cable assemblies?
The K (keyed) shroud option includes a polarizing key that physically blocks insertion of the cable mate in the wrong orientation, preventing pin-to-pin mis-alignment across all 46 positions during field installation — critical in robotics and motor-drive systems where a single miswire can damage signal or power circuits.
For a 46-position dual-row design at 2.00mm pitch, how does STMM-123-02-TM.SM.LM-D-SM-K-TR compare to an equivalent 1.27mm pitch connector?
At 2.00mm pitch, the 46-position STMM-123-02-TM.SM.LM-D-SM-K-TR spans roughly 47mm, versus about 30mm for a 1.27mm-pitch alternative. The larger 2.00mm pitch better accommodates 24 AWG to 28 AWG wires in field-wired industrial harnesses, while the tighter 1.27mm pitch suits denser PCB-to-PCB stacking with finer wire gauges.
