Frequently Asked Questions
How many positions does the STMM-123-02-L-D-SM-K-TR have, and what pitch does it use?
The STMM-123-02-L-D-SM-K-TR is a 46-position dual-row connector with 2.00 mm pitch, providing a total of 46 signal positions for cable-to-board applications in industrial and medical equipment requiring high pin-count SMT connectivity.
How does the keying feature on the STMM-123-02-L-D-SM-K-TR protect against miswiring in multi-connector assemblies?
The K-suffix keying on the STMM-123-02-L-D-SM-K-TR uses a mechanically asymmetric shroud that blocks mating unless the cable connector is correctly oriented, preventing reversal of a 46-pin, 2.00 mm pitch cable assembly and protecting downstream circuitry from reverse-polarity damage.
Can the STMM-123-02-L-D-SM-K-TR be used in fully automated SMT reflow assembly lines?
Yes, the STMM-123-02-L-D-SM-K-TR is supplied in tape-and-reel (TR) format compatible with standard pick-and-place equipment, and its SMT (SM) footprint supports standard lead-free reflow soldering profiles, making it fully compatible with automated SMT assembly for high-volume industrial PCB production.
What mating cable assembly series is compatible with the STMM-123-02-L-D-SM-K-TR for field wiring?
The STMM-123-02-L-D-SM-K-TR mates with Samtec's corresponding 2.00 mm pitch cable mate plug assemblies, typically accommodating 26 AWG to 28 AWG wires rated for approximately 1 A per contact, supporting signal and low-power supply routing in industrial field-wiring applications.
