Eaton SM20ML1S31 Crimp Contact - RoHS Compliant
Part Number: SM20ML1S31
Quick Summary
The Eaton SM20ML1S31 crimp contact enables reliable, compact connections in Souriau SC/SM series harnesses. Engineers often battle inconsistent crimp quality and premature wear in tight assemblies. It carries RoHS and REACH compliance, with gold-on-active plating for corrosion resistance and nickel on the rear for durability. Optimized for 16 and 20 AWG wire and bulk installation, this part supports scalable manufacturing and traceable quality in power and data interfaces. Designed for industrial automation environments, it minimizes downtime by providing repeatable crimps and easy replacement in fielded harnesses. The compact 28 mm length, 2.7 mm height, and 3.5 mm width help engineers plan dense connector layouts without compromising electrical performance.

Manufacturing process
Stamped and formed
Feature: stamped and formed manufacturing is the standard method for these contacts, delivering precise geometry and repeatable crimps. Business impact: higher first-pass yield, reduced scrap, and lower rework costs on high-volume automation builds. Application: ideal for Souriau SC/SM harnesses in industrial controls where connector integrity affects uptime and performance. Feature: wire size compatibility spans 22 AWG minimum to 20 AWG maximum, covering common control, sensor, and power strands. Business impact: enables procurement consolidation and reduces SKU proliferation while preserving crimp reliability. Application: data and power interfaces in automation panels and machine mounting harnesses benefit from this versatility. Feature: contact plating combines gold on the active portion with nickel on the rear. Business impact: minimizes contact resistance, enhances corrosion resistance, and extends service life in harsh environments. Application: reliable operation in challenging factory floors, outdoor enclosures, and equipment cabinets with frequent mating cycles. Feature: bulk packaging and loose delivery streamline automation tooling and line-side stocking. Business impact: lowers handling time, reduces packaging waste, and speeds replenishment on assembly lines. Application: suitable for automated crimping machines and Kanban-based inventories in modern manufacturing facilities. Feature: RoHS and REACH environmental compliance support regulatory readiness and sustainability goals. Business impact: simplifies cross-border deployment and customer audits, reducing compliance risk. Application: approved for global deployments in automotive, industrial, and data communication systems. Feature: compact footprint—28 mm length, 2.7 mm height, 3.5 mm width, and 2.7 mm diameter, with a body weight around 0.4 g. Business impact: enables dense connector layouts and predictable space planning in crowded panels. Application: space-constrained harness assemblies in SC/SM configurations with consistent mating interfaces. Feature: compatibility with the Souriau SC/SM housings and the broader family of stamped and formed contacts. Business impact: accelerates replacement cycles, supports BOM standardization, and simplifies stocking for spares. Application: maintenance and upgrade projects in automation lines where downtime must be minimized.

FAQs
SM20ML1S31 is a male stamped and formed contact intended for Eaton Souriau SC and SM series connectors. It mates with standard Souriau housings in those families, ensuring consistent alignment and contact integrity. The contact is supplied in bulk, enabling streamlined automation workflows and easy integration with existing crimp tooling and line-side stocking.
Key specifications include 28 mm length, 2.7 mm height, 3.5 mm width, and 0.4 g weight, with a wire size range of 22–20 AWG. The contact supports 16 AWG sizing, has gold-on-active plating with nickel on the rear, and is RoHS/REACH compliant. These factors ensure reliable mating, low resistance, and durable performance in automation environments.
Yes. The compact footprint (28 mm x 2.7 mm x 3.5 mm) enables dense harness layouts, while gold-on-active plating and nickel rear plating provide corrosion resistance and durability through frequent mating cycles. This makes the contact well-suited for harsh factory floors, enclosed cabinets, and other demanding industrial settings.
SM20ML1S31 meets RoHS and REACH environmental requirements, supporting regulatory compliance across global markets. These certifications help with supplier audits and documentation, while the materials choices align with sustainability goals in automation projects.
Stamped and formed contacts offer tight tolerances and repeatable crimps, reducing scrap and rework. Bulk packaging lowers handling costs, while durable plating extends service life, reducing downtime. Overall, customers see faster maintenance cycles, lower replacement rates, and a tangible return on investment in high-volume automated lines.
