What are the key features of STMM-118-02-H-D-SM?
- 18 dual-row positions on 2.00 mm pitch shrouded housing providing polarized, keyed mating for error-free cable-to-board assembly
- Surface mount horizontal termination compatible with standard SMT reflow soldering processes in automated PCB production
- Gold-plated contacts delivering low-resistance signal connections with high mating cycle durability for industrial wire-to-board interfaces
What is STMM-118-02-H-D-SM used for?
STMM-118-02-H-D-SM is designed for cable-to-board applications in industrial control panels, robotics end-effectors, and embedded sensor modules where 18 signals must be reliably terminated at 2.00 mm pitch. The shrouded housing prevents mis-mating during field assembly and maintenance, reducing wiring errors in multi-axis motor drives and programmable logic controller I/O modules. Its SMT footprint integrates seamlessly into high-volume automated PCB assembly lines.

Frequently Asked Questions
How many positions does STMM-118-02-H-D-SM provide and what is its contact pitch?
STMM-118-02-H-D-SM provides 18 positions arranged in a dual-row layout on 2.00 mm pitch, giving a total connector width of approximately 18 mm. This pitch and position count is commonly used for 16-signal plus 2-power/ground configurations in industrial sensor interfaces and motor control wiring harnesses.
How does the shrouded housing of STMM-118-02-H-D-SM prevent mis-mating in field-service environments?
The polarized shroud on STMM-118-02-H-D-SM accepts only the correct 18-position 2.00 mm cable-mate plug in the correct orientation, preventing reverse-insertion or partial mating. This keying is critical in field-serviced equipment such as industrial robots and PLC I/O modules where technicians may replace cable assemblies under time pressure without detailed documentation.
What is the typical current rating per contact for STMM-118-02-H-D-SM, and how should power contacts be assigned in a mixed signal-power design?
SAMTEC STMM series connectors at 2.00 mm pitch are typically rated at 2 A per contact. For a design requiring a 5 V power rail at 4 A, designers should allocate 2 contacts in parallel for VCC and 2 contacts for GND, leaving the remaining 14 positions for signal lines in an 18-position STMM-118-02-H-D-SM connector.
When would a designer choose STMM-118-02-H-D-SM over a 2.54 mm pitch equivalent for the same 18-position requirement?
Choosing 2.00 mm pitch STMM-118-02-H-D-SM over a 2.54 mm equivalent reduces the connector footprint by approximately 20% in the mating axis, saving roughly 5 mm of PCB length. This space saving is significant in compact embedded modules, wearable industrial devices, and handheld instruments where the PCB width is constrained below 50 mm.
