Eaton SC20M1S31 Crimp Contacts - SC/SM 16 & 20, Gold/Nickel, REACH RoHS
Part Number: SC20M1S31
Quick Summary
Eaton SC20M1S31 crimp contacts provide reliable female terminations for 16–20 AWG wires in harness assemblies. In high-volume equipment builds, inconsistent crimps or plating can cause intermittent connections and costly field failures. The parts comply with RoHS and REACH environmental standards, and the contacts use gold on the active portion with nickel on the rear to improve durability. Designed for the SC/SM series connectors and supplied on reels, these stamped and formed terminals support automated crimping while reducing scrap and cycle time. This combination delivers regulatory compliance, improved reliability, and lower total cost of ownership in automotive, industrial, and machine-building applications.

Manufacturing process
Stamped and formed
Feature: stamped and formed production ensures precise geometry and consistent contact pressure. Business Impact: higher mating reliability and reduced resistance drift over time. Application: suitable for automated crimping on SC/SM connectors in control panels and vehicle harnesses. Feature: wire size compatibility spans 22–20 AWG with distinct #16 and #20 contact options. Business Impact: enables a single terminal family to serve multiple harness variants, lowering stocking complexity and project lead times. Application: flexible in mixed-wire assemblies without sacrificing crimp quality. Feature: gold on active part with nickel on rear plating. Business Impact: improved corrosion resistance and signal integrity in harsh environments, extending service life. Application: long-life electrical connections in industrial equipment and machinery. Feature: reeled packaging for efficient feeding in automated systems. Business Impact: reduces handling time, increases line throughput, and minimizes operator intervention. Application: high-volume manufacturing lines with reel-fed crimpers. Feature: compact dimensions (19 mm length, 3.3 mm height, 3.1 mm width) and light 0.3 g weight. Business Impact: enables compact connector footprints and lighter harnesses, aiding in space-constrained enclosures. Application: densely packed control cabinets and portable equipment. Feature: RoHS and REACH compliance. Business Impact: supports regulatory adherence across automotive and industrial sectors, mitigating compliance risk. Application: procurement for regulated markets and certified builds.

FAQs
SC20M1S31 is designed for Eaton Souriau SC/SM series connectors and supports 16/20 AWG wire ranges. The contacts are female (socket) stamped and formed, delivered on reels to streamline automated assembly, and are compatible with common SC/SM crimp crimping tools and feed systems.
The contact uses gold plating on the active portion and nickel on the rear portion to enhance conductivity and wear resistance. It also complies with RoHS and REACH environmental standards, ensuring regulatory compliance in industrial and automotive applications.
The contact measures 19 mm in length, 3.3 mm in height, and 3.1 mm in width, with an estimated weight of 0.3 g. It is supplied in reeled packaging to support high-speed, automated crimping on production lines.
Yes. With RoHS and REACH compliance, gold-on-active/nickel-on-rear plating, and reel packaging for automation, these contacts are well-suited for automotive electronics and industrial control panels requiring reliable terminations on 16/20 AWG harnesses.
By delivering consistent crimps, reduced scrap from stamping/forming, and efficient reel-fed processing, SC20M1S31 lowers maintenance and labor costs in high-volume assemblies while maintaining long-term reliability in harsh operating environments.
