Frequently Asked Questions
How many contact positions does the STMM-123-02-TM.SM.LM-D-SM provide and how are they arranged?
The STMM-123-02-TM.SM.LM-D-SM provides 46 total contact positions arranged in 2 rows of 23 pins each at a 2.00 mm pitch. This dual-row shrouded terminal strip layout enables high-density signal routing between a PCB and a mating cable connector in industrial, embedded computing, and test equipment applications where many signals must be routed through a single compact connector.
What are the differences between the TM, SM, and LM termination variants of the STMM-123-02 series?
The STMM-123-02 series offers three surface-mount termination variants: top-mount (TM) for standard upright PCB connections, standard surface-mount (SM) for typical SMT reflow assembly, and low-mount (LM) for reduced height profiles where board clearance is under 2 mm. Selecting the correct variant allows engineers to optimize the connector stack height for specific enclosure, mating cable direction, and PCB layout constraints.
In which multi-signal board-to-cable systems is the STMM-123-02-TM.SM.LM-D-SM most commonly used?
The STMM-123-02-TM.SM.LM-D-SM is commonly used in test and measurement instruments, industrial automation controllers, and high-density embedded backplane systems where 46 signals at 2.00 mm pitch must be routed through a single compact connector. Its shrouded dual-row design prevents mis-mating, which is critical in field-replaceable cable harness applications where incorrect connections could damage sensitive electronics or disrupt industrial processes.
