Key Features
- 18-position dual-row shrouded terminal strip on 2.00 mm pitch providing polarized cable-to-board mating in a compact SMT footprint
- Male square-pin contact style with low-profile (L) design enabling reliable signal termination in space-constrained PCB layouts
- Black insulator housing with integrated shroud preventing mis-mating and providing mechanical polarization for field cable assembly
Applications
The STMM-109-02-L-D-SM is suited for cable-to-board interface applications in industrial control panels, embedded systems, and consumer electronics requiring a compact 2.00 mm pitch shrouded surface mount connector with 18 dual-row positions. Its SMT termination style and male square-pin contacts mate with standard SAMTEC SFML or compatible cable housings, enabling field-replaceable cable assemblies in tight PCB layouts. The polarized shroud ensures correct orientation during assembly and maintenance in equipment where mis-mating would risk circuit damage.

Frequently Asked Questions
How many signal positions does the STMM-109-02-L-D-SM provide and how are they arranged across the dual-row layout?
The STMM-109-02-L-D-SM provides 18 total positions arranged in 2 rows of 9 contacts each on a 2.00 mm pitch. This dual-row (D) configuration within a body length of 0.951 inches allows designers to route 18 independent signals through a single compact connector, with the shroud ensuring correct polarization during cable mating in automated and manual assembly environments.
What PCB assembly process is compatible with the STMM-109-02-L-D-SM and how does the SMT termination simplify manufacturing?
The SM (surface mount) suffix confirms the STMM-109-02-L-D-SM is designed for reflow soldering in standard SMT production lines, eliminating the need for wave soldering or through-hole drilling. At a 2.00 mm pitch, the 18-position dual-row footprint is compatible with typical SMT placement tolerances, and the connector can be placed by automated pick-and-place equipment using vacuum nozzles sized for the 0.951 x 0.429 inch body. This reduces assembly steps and cost compared to equivalent through-hole cable mate connectors.
Is the STMM-109-02-L-D-SM compatible with standard SAMTEC cable assemblies and what is the mating connector family?
The STMM-109-02-L-D-SM is a board-side cable mate terminal strip designed to pair with SAMTEC's SFML or equivalent female cable housing assemblies on the 2.00 mm pitch standard. The male square-pin contacts with an 18-position dual-row layout accept standard discrete wire crimp terminals in 26 AWG to 30 AWG wire gauges, supporting cable harnesses rated for signal currents up to 1 A per contact. Confirm the specific mating housing part number and wire gauge range with SAMTEC's STMM series documentation for the correct cable assembly selection.
