Eaton SM20ML1S18 Crimp Contact - RoHS & REACH
Part Number: SM20ML1S18
Quick Summary
SM20ML1S18 crimp contact by Eaton provides a reliable, stamped and formed male contact for Souriau SC/SM series connectors used in industrial automation and challenging field environments. Users often struggle with weak crimps, inconsistent plating wear, and regulatory compliance costs when integrating mixed-technology connectors. These contacts achieve RoHS and REACH compliance, delivering corrosion resistance through gold active-plating and tin on the rear part, with robust mating and long-term reliability. Designed for 22–20 AWG wire and a tight 28 mm footprint, they deliver cost-efficient, scalable assembly across high-mix, low-volume production and service upgrades. Bulk packaging supports efficient supply chain and reduce handling time for service teams.

Manufacturing process
Stamped and formed
Stamped and formed manufacturing yields precise geometry and consistent spring force across production lots. This translates to repeatable crimps, reduced connection variance, and lowered risk of intermittent contact in vibration-heavy equipment. Application within Souriau SC/SM series makes these contacts ideal for automated machinery, robotics, and aerospace harnesses where reliability is mission-critical. Gold on active part reduces oxidation on the power-carrying surface, while tin on the rear part lowers costs where corrosion risk is lower, delivering long-term signal integrity. For high-reliability environments, this plating scheme enhances contact lifetime and maintains low contact resistance even after frequent mating cycles. Wire size compatibility from 22 to 20 AWG minimizes inventory variety and simplifies field upgrades, while bulk packaging lowers handling costs and accelerates assembly lines. The 28 mm length and small footprint enable dense panel-mate layouts without sacrificing performance. These features collectively support cost efficiency, regulatory compliance, and scalable deployment across mixed-systems installations.

FAQs
The SM20ML1S18 is a male stamped and formed crimp contact designed for Eaton Souriau SC/SM series connectors. It supports 22–20 AWG wires and pairs with bulk, theater-ready harness assemblies that require reliable, RoHS/REACH-compliant performance in industrial automation, robotics, and aerospace applications.
The contact measures 28 mm in length, stands 2.7 mm high, and 3.5 mm wide with a 2.7 mm diameter profile, and weighs 0.4 g. These compact dimensions support high-density connector layouts while preserving robust electrical performance.
Yes. The SM20ML1S18 is specified as RoHS and REACH compliant, aligning with global environmental and regulatory requirements and reducing compliance risk in regulated applications such as medical, industrial, and aerospace equipment.
Use a crimp tool compatible with 16 AWG contact size and the 22–20 AWG wire range. Ensure proper alignment and crimp profile to achieve reliable mating force and long-term contact integrity; verify plating integrity (gold on active, tin on rear) after installation to maintain corrosion resistance.
Typical applications include connectors in automated machinery, control panels, and rugged harnesses used in industrial automation, energy, and aerospace environments. The combination of precise stamped-and-formed geometry, dual-plating, and bulk packaging supports scalable production, easy field servicing, and continued performance under vibration and environmental exposure.
