Eaton SM20M1S31 Souriau SC/SM Crimp Contacts - RoHS REACH
Part Number: SM20M1S31
Quick Summary
Eaton SM20M1S31 crimp contacts enable secure pin connections in Souriau SC/SM connectors for compact, high-reliability assemblies. When contacts are mis-sized or poorly plated, crimp reliability suffers, leading to intermittent signals and costly field failures. The part carries RoHS and REACH compliance, with gold on the active part and nickel on the rear to boost corrosion resistance in demanding environments. Compatible with 22–20 AWG wire and reeled packaging, it supports automated assembly while reducing waste and cycle times. Designed for automotive and industrial wiring, stamped and formed manufacturing balances cost with performance, delivering predictable service life and traceability.

Feature → Business Impact → Application: The SM20M1S31 is a male stamped and formed crimp contact designed for the Souriau SC/SM series, reinforcing a consistent crimp profile that minimizes rework and field failures in high-volume harness builds. This translates to improved first-pass yields in automotive and industrial assemblies where reliability is non-negotiable. The gold-on-active, nickel-on-rear plating enhances contact longevity and resistance to corrosion, boosting uptime in harsh environments and reducing maintenance costs for fleet and plant operations. Its compact 28 mm length, 2.7 mm height, and 3.5 mm width deliver a small-form-factor footprint suitable for densely packed connectors, enabling slimmer harnesses without compromising signal integrity. Reeled packaging supports automation and high-speed insertion, lowering labor time and enabling scalable production. The 22–20 AWG wire range broadens compatibility with common automotive cables and sensor wiring, while stamped-and-formed manufacturing keeps part cost competitive for large builds. This combination addresses common objections about durability, supply consistency, and total cost of ownership in complex wiring systems.

FAQs
SM20M1S31 is a male stamped and formed crimp contact designed for Eaton Souriau SC/SM series connectors. It fits wire sizes 22–20 AWG and ships on reeled packaging for automated insertion. Use with Souriau SC/SM housings per the official mating document BSC200178001A. Ensure crimp tooling matches the stamped geometry to maintain reliability.
The SM20M1S31 is a crimp-type contact with 22–20 AWG wire compatibility, 28 mm length, 2.7 mm height, 3.5 mm width, and 2.7 mm diameter. It weighs 0.4 g and uses gold plating on the active portion with nickel on the rear. It is RoHS and REACH compliant and packaged reeled for automated assembly.
Yes. The contact is designed for Souriau SC/SM connectors used in automotive wiring and industrial harnesses. Its gold-on-active plating and nickel-on-rear plating provide corrosion resistance, while RoHS/REACH compliance supports regulatory requirements in automotive supply chains. The reels and stamped-formed process support consistent quality in high-volume manufacturing.
The SM20M1S31 meets RoHS and REACH environmental standards, which helps ensure regulatory compliance in Europe and other regions. The combination of plating and material selection is aimed at long-term reliability in challenging operating conditions common to automotive and industrial applications.
The gold-on-active and nickel-on-rear plating reduces contact wear and corrosion, lowering maintenance frequency and field repairs. The reeled packaging supports automation, reducing labor costs and cycle times in high-volume assembly. Overall, this translates to lower total cost of ownership through improved reliability and predictable performance over the product lifecycle.
