Eaton SM16ML1S31 Stamped Contact - RoHS Compliant
Part Number: SM16ML1S31
Quick Summary
Eaton SM16ML1S31 Stamped Contact is a male crimp contact used for high-density, reliable interconnections in Souriau SC/SM-series assemblies. Manufacturers frequently grapple with ensuring consistent plating and reliable mating in compact connectors. This design complies with RoHS and REACH environmental standards, supporting regulatory compliance across global supply chains. The gold-on-active plating with nickel rear surface delivers durable connections for 16 AWG to 18 AWG wire, reducing maintenance costs and stock complexity. In high-density assemblies, faster crimping and guaranteed contact integrity translate to lower field failures and longer service life. This makes SM16ML1S31 a reliable choice for aerospace, industrial automation, and machinery OEMs seeking consistent performance across shipments.

FAQs
SM16ML1S31 is a stamped and formed male crimp contact designed for Eaton Souriau SC/SM series interconnects. It supports 16–18 AWG wire terminations and is intended for use in high-density assemblies where precise mating geometry and consistent crimp quality are critical. It complements bulk-sourced terminals in automation panels and control harnesses.
The SM16ML1S31 supports a wire range from 18 AWG minimum to 16 AWG maximum. This gives flexibility for mixed-harness designs in industrial automation, robotics, and machinery where both smaller and slightly larger conductors are terminated in the same connector family.
SM16ML1S31 uses gold plating on the active contact portion and nickel on the rear. This combination delivers excellent corrosion resistance, improved contact durability, and stable signal integrity over many mating cycles, which translates to lower maintenance and fewer field failures in demanding environments.
Yes. The contact is manufactured to RoHS and REACH environmental standards, aligning with global regulatory requirements for electrical components. This supports compliant sourcing and smoother supply-chain management for OEMs operating across multiple regions.
Key dimensions include a length of 28 mm, width of 3.7 mm, height of 3.2 mm, and a weight of 0.4 g. The packaging type is Bulk, which is advantageous for high-volume harness builds and lean procurement strategies in automation and machinery manufacturing.
