Eaton SC20ML1S31 Stamped & Formed Crimp Contact - RoHS/REACH
Part Number: SC20ML1S31
Quick Summary
The Eaton SC20ML1S31 stamped and formed crimp contact delivers reliable female socket connections for compact harnesses in industrial electronics. Engineers often struggle with intermittent mating, plating wear, and slow assembly when wiring densely packed connectors. This part is RoHS and REACH compliant, designed to meet CE conformity expectations in many markets, and features gold on the active contact with nickel on the rear for durability and corrosion resistance. By leveraging compatibility with the Souriau SC/SM series, this contact supports efficient, scalable assembly and consistent electrical performance across high-volume builds, delivering lower maintenance costs and improved mean time between failures. The combination of compact dimensions and robust plating translates to tangible business value in modern automation environments.

Manufacturing process
Stamped and formed
The SC20ML1S31 is produced using stamped and formed manufacturing, delivering consistent geometry and reliable seating in tight connector pockets. This process minimizes insertion forces and improves mating reliability in high-density harnesses used in industrial controls. The contact supports wire sizes from 22 to 20 AWG, aligning with common micro-harnesses, while matching the Souriau SC/SM family in size. Gold on the active part with nickel on the rear part provides low contact resistance and long-term durability, boosting signal integrity in vibration-prone environments. Bulk packaging reduces cost per unit and streamlines high-volume assembly, supporting automated crimping lines and easier material handling with less waste. RoHS and REACH compliance ensures regulatory alignment across global markets, simplifying multi-region procurement and maintenance planning.

FAQs
SC20ML1S31 is a female stamped and formed crimp contact designed for use with Eaton Souriau SC/SM series sockets. It fits size #16 (1.6 mm) contacts and is compatible with wires in the 22–20 AWG range, enabling straightforward integration into existing SC/SM harnesses without adapters or rework.
Use a standard crimping tool compatible with 22–20 AWG copper conductors and the SC/SM stamped contacts. Ensure the wire insulation is stripped to the correct length, insert the wire fully, and actuate the crimp to specified terminals. Verify crimp height and continuity after installation to guarantee optimal contact performance.
Yes. The SC20ML1S31 is RoHS and REACH compliant, aligning with environmental and regulatory requirements across many regions. While CE conformity can vary by overall assembly, using this contact within a compliant SC/SM housing supports regulatory readiness for multi-region deployments.
Key specs include 19 mm length, 3.3 mm height, 3.1 mm width, and 0.3 g weight. It accommodates 16 AWG contact size, with wire compatibility 22–20 AWG. Plating is gold on the active portion and nickel on the rear, providing low resistance and durable wear characteristics for repeated mating cycles.
Prioritize consistent crimp quality with proper tooling, verify crimp height and seating depth, and maintain clean terminals free of corrosion. The compact 19 mm length and bulk packaging support high-density harnesses and efficient feeder systems, reducing misfeeds and rework while maintaining electrical integrity in automated assembly lines.
