Frequently Asked Questions
How many positions and what pitch does the STMM-122-02-S-D-SM-K-TR provide?
The STMM-122-02-S-D-SM-K-TR is a 44-position dual-row connector with a 2.00 mm pitch, housed in a shrouded body measuring 1.959 inch in length and 0.24 inch in depth, providing a compact dual-row layout for high-density board-to-cable signal routing in industrial and embedded applications.
What contact finish does the STMM-122-02-S-D-SM-K-TR use and why does it matter for connector reliability?
The connector uses tin (Sn) plating over a nickel (Ni) barrier on its termination contacts, which provides good corrosion resistance, acceptable contact resistance across 44 positions, and compatibility with standard solder reflow assembly, making it reliable for industrial environments with moderate temperature and humidity cycling.
Which applications are best served by the shrouded and keyed design of the STMM-122-02-S-D-SM-K-TR?
The shrouded, keyed housing is particularly valuable in factory automation panels, robotics controllers, and medical instruments where field technicians must repeatedly mate and un-mate a 44-pin, 2.00 mm pitch cable assembly without risk of misalignment or reversed insertion, reducing assembly errors and protecting all 44 signal pins during handling.
Is the STMM-122-02-S-D-SM-K-TR supplied in tape-and-reel packaging suitable for SMT pick-and-place assembly?
Yes, the TR suffix indicates tape-and-reel packaging, and the SM designation confirms surface-mount termination, making the STMM-122-02-S-D-SM-K-TR compatible with automated SMT pick-and-place lines and standard solder reflow processes for high-volume production of boards requiring 44-position, 2.00 mm pitch dual-row connectors.
