Frequently Asked Questions
How many positions and rows does the STMM-109-02-S-D-SM-K-TR provide in its connector body?
The STMM-109-02-S-D-SM-K-TR features 18 positions arranged in a dual-row (D) configuration with 9 contacts per row on a 2.00 mm pitch, providing a compact footprint for 18-conductor cable harness connections to SMT PCB assemblies in industrial and embedded designs.
What assembly advantages does the tape-and-reel packaging of STMM-109-02-S-D-SM-K-TR provide?
The TR (tape-and-reel) packaging allows the STMM-109-02-S-D-SM-K-TR to be fed directly into automated pick-and-place equipment during SMT assembly, enabling consistent placement of all 18-position connectors at throughput rates exceeding 5,000 placements per hour typical of modern SMT lines.
Why does the keyed (K) shroud matter when assembling cable harnesses to STMM-109-02-S-D-SM-K-TR?
The polarization key (K) in the shrouded housing mechanically blocks reversed or offset cable mate insertion across the 18-position dual-row connector, preventing wiring errors that could damage circuits or reverse signal polarity, which is especially important in multi-conductor industrial harnesses with identical-looking pins at 2.00 mm pitch.
Which SAMTEC cable assembly series are compatible as mating connectors for the STMM-109 series?
SAMTEC's FFSD and IDSD IDC cable assemblies mate with the STMM-109 series at 2.00 mm pitch, providing 18-conductor ribbon options in lengths from 100 mm to 600 mm, while discrete-wire Micro-MaTch cable assemblies also support individual conductor routing to the 2.00 mm pitch shrouded receptacle.
