Eaton SM24ML1S31 Stamped Crimp Contacts - RoHS
Part Number: SM24ML1S31
Quick Summary
SM24ML1S31 stamped crimp contacts deliver reliable connections for Eaton Souriau SC/SM assemblies in industrial equipment. In dense harnesses and high-vibration environments, inconsistent crimps and corrosion can threaten performance. This part supports RoHS and REACH compliance, with gold on the active contact and nickel on the rear for longevity and corrosion resistance. For manufacturers optimizing 24–26 AWG wiring in automation and machinery, these contacts offer cost-effective, regulatory-compliant performance and easier procurement through bulk packaging.

FAQs
SM24ML1S31 is a male stamped and formed crimp contact designed for Eaton Souriau SC/SM series connectors. For installation, trim the conductor to 24–26 AWG, prepare the crimp using the appropriate tool, and verify that the contact seats fully into the housing cavity with a audible or tactile cue. Use the gold-on-active, nickel-on-rear plating to ensure corrosion resistance; test crimp integrity with a pull test to meet your assembly standard.
SM24ML1S31 supports 24–26 AWG wire. Crimp quality directly influences contact resistance, signal integrity, and vibration resilience. Use the correct crimp profile and tooling to achieve a consistent, fully seated crimp. Poor crimps can introduce high resistance, intermittent connections, or mechanical failure under vibration, which this part is engineered to mitigate with its stamped-and-formed geometry.
Yes. SM24ML1S31 features RoHS and REACH compliance, aligning with environmental and regulatory requirements across many regulated markets. This helps simplify supplier qualification, reduces risk of non-compliance in multi-region deployments, and supports ongoing product stewardship in aerospace, automotive, and industrial automation programs.
This contact excels in compact Souriau SC/SM connector assemblies found in automation panels, machinery control systems, and rugged industrial equipment. Its 28 mm length and 2.5 mm height enable use in space-constrained harnesses, while the 24–26 AWG range supports common control and sensor wiring. The gold-on-active plating and nickel rear provide reliable long-term performance in vibration-prone environments.
In high-volume deployments, SM24ML1S31 offers predictable crimping and durable plating that reduce maintenance needs and downstream failures. The bulk packaging lowers part handling and procurement costs, while RoHS/REACH compliance eases cross-border sourcing. Long-term reliability reduces mean time between failures (MTBF) and spare parts expenses, delivering a favorable return on investment in automation and control panel programs.
