Eaton SM24M1S31 Crimp Contact for Souriau SC/SM Series RoHS
Part Number: SM24M1S31
Quick Summary
Eaton SM24M1S31 crimp contact provides reliable pin connections for Souriau SC/SM series harness assemblies. Field failures from poor crimp terminations, plating wear, or corrosion-driven impedance spikes drive downtime and rework. The part is RoHS and REACH compliant, supporting safe, regulated deployment, while ensuring long-term compatibility with common industrial connectors. For integrators, this translates to reduced warranty claims, faster terminations, and easier sourcing across global supply chains. Engineers will value the compact footprint—28 mm length, 2.5 mm height, and 3.2 mm width—which fit tight panel gaps and dense harness routes. Gold on the active contact and nickel on the rear portion deliver robust corrosion resistance, matching demanding industrial cycles.

FAQs
The SM24M1S31 is a male crimp contact designed for Eaton Souriau SC/SM series assemblies, compatible with 24 to 26 AWG wire. It supports stamped #16 (1.6 mm) and #20 (1.0 mm) contacts and ships on a reel to suit automated crimping lines. This flexibility helps maintain consistent termination geometry across mixed harnesses in high-volume production.
Gold plating on the active portion provides superior corrosion resistance and signal integrity for mating surfaces, while nickel plating on the rear portion enhances wear resistance during repeated connections. Together, they reduce contact resistance increases and maintenance needs, contributing to longer service life in demanding industrial applications. The stamped-formed geometry further supports consistent contact force across cycles.
Yes, the SM24M1S31 is RoHS and REACH compliant, making it suitable for global deployments in machinery, automation, and electrical systems. This compliance helps meet regulatory requirements in key markets and reduces supply-chain risk when sourcing connectors and crimp contacts for international projects.
Use tooling calibrated for 24-26 AWG and ensure proper wire strip length to achieve a secure crimp. The reeled packaging supports high-speed, automated feeding, minimizing handling time and improving repeatability. Verify crimp height and girth against recommended specifications to avoid loose terminations or excessive deformation.
Typical failures include poor crimp terminations, plating delamination, and corrosion under environmental exposure. The SM24M1S31 design combats these with stamped-formed geometry for stable contact force, gold active plating with nickel rear plating for corrosion and wear resistance, and RoHS/REACH compliance to ensure reliable, compliant operation across markets.
