What are the key features of STMM-114-02-S-D-SM-K-TR?
- 28-position dual-row shrouded terminal strip at 2.00 mm pitch offering keyed polarity protection to prevent mis-mating in cable harness assemblies
- Tin (Sn) over Nickel (Ni) barrier termination contacts compatible with lead-free SAC305 reflow for reliable SMT solder joints
- Surface mount form factor with tape-and-reel (-TR) packaging enabling automated pick-and-place assembly in high-volume production
What is STMM-114-02-S-D-SM-K-TR used for?
The STMM-114-02-S-D-SM-K-TR is well suited for board-to-wire cable harness connections in industrial automation controllers, robotics, and power distribution modules where a shrouded connector prevents accidental wire reversal. Its 2.00 mm pitch dual-row layout supports 28 signal or power lines in a 1.335 inch body, accommodating multi-channel sensor, actuator, and control wiring in compact equipment. The SMT design integrates into standard reflow assembly lines, reducing manual wiring work in mid-volume production.

Frequently Asked Questions
How many positions and what pitch does the STMM-114-02-S-D-SM-K-TR provide in its dual-row layout?
The STMM-114-02-S-D-SM-K-TR provides 28 positions in a dual-row configuration with 2.00 mm pitch, giving a body length of 1.335 inches (33.9 mm). The 2.00 mm pitch supports higher current per contact than 1.27 mm pitch alternatives while remaining more compact than 2.54 mm pitch connectors used in legacy industrial wiring.
What advantage does the shrouded design of the STMM-114-02-S-D-SM-K-TR provide over unshrouded pin headers?
The shroud physically surrounds the male pins, preventing mis-alignment during cable mating in dark or confined equipment interiors. Combined with the -K keying option that adds an asymmetric polarization key, the shrouded design ensures the mating cable connector can only be inserted in the correct orientation, preventing reversed wiring that could damage circuits carrying 5 V to 24 V supply voltages.
What termination finish does the STMM-114-02-S-D-SM-K-TR use and how does it affect solderability?
The termination contacts use tin (Sn) with a nickel (Ni) barrier, which provides good solderability in standard lead-free SAC305 reflow processes peaking at 260°C. Tin termination maintains its solderability for 12 months or more under standard EIA storage conditions, making this connector suitable for manufacturing environments with extended component warehouse lead times.
When is the STMM-114-02-S-D-SM-K-TR a better procurement choice than a through-hole shrouded header for industrial designs?
The SMT variant eliminates the need for hand-soldering or wave soldering processes required by through-hole headers, reducing per-board assembly cost when production volumes exceed 500 units per month. The tape-and-reel packaging allows the 28-pin connector to be processed alongside other SMT components in a single reflow pass, cutting assembly time by removing the need for a separate through-hole insertion step.
