Feature → Business Impact → Application: Quick mating with push-pull coupling reduces assembly time and labor costs while improving reliability in high-mix panel builds. This enables faster line changeovers in automated equipment and robotics applications using the SMS9P3 as a dense 9-position I/O link. Application: Industrial automation panels, machine control cabinets, and robotic system harnesses benefit from reduced downtime and easier serviceability. Feature → Business Impact → Application: 9-position, straight plug design delivers compact footprint without sacrificing performance, enabling tighter panel layouts and scalable I/O density. Application: Drive controllers, CNC modules, and servo interfaces require reliable, space-efficient connectors. Feature → Business Impact → Application: Crimp contact termination supports robust, vibration-tolerant connections with repeatable performance; sourcing remains flexible as contacts are purchased separately. Application: Cable-to-board assemblies in harsh environments where maintenance access is limited. Feature → Business Impact → Application: Push-Pull coupling provides secure mating under vibration and temperature cycling, minimizing intermittent failures; reduces rework and warranty costs. Application: Equipment in automotive, automation, and packaging lines where consistent connection is critical. Feature → Business Impact → Application: RoHS, REACH compliance plus UL94 V0 rating delivers regulatory confidence and safer operations in hazardous environments. Application: Industrial machinery and control panels with strict environmental requirements. Feature → Business Impact → Application: IP30 enclosure protection supports panel-level ingress resistance for indoor automation setups; combined with 46.5 mm length and 25 mm width, enables compact, robust harnessing. Application: Small footprint control boxes and space-constrained installations. Feature → Business Impact → Application: SMS series compatibility ensures long-term supply and modular upgrades; ease of integration reduces total cost of ownership. Application: Systems upgrading from older Souriau or rival connectors, enabling phased migration.

FAQs
SMS9P3 is a straight plug from the SMS series designed for 9-crimp contact assemblies. Ensure your panel cutout accommodates a 25 mm width, 46.5 mm depth, and 9-position layout. Use separate crimp contacts (not included) and follow standard harness grounding practices. The no backshell option means you must plan for adequate cable routing and strain relief within the enclosure.
SMS9P3 features nine crimp contacts in a 9-cavity design with a 46.5 mm depth, 25 mm width, and 5.9 mm height. It offers IP30 protection, operates from -55 °C to 125 °C, and is RoHS and REACH compliant with UL94 V0 flammability, ensuring regulatory compliance and reliability in tough industrial settings.
Yes, the push-pull coupling provides secure mating and helps resist vibration-induced disengagement. However, since there is no backshell included, you should implement proper cable routing and strain relief to mitigate movement in high-vibration environments and maintain long-term integrity.
The 9-position density supports compact panel layouts and faster assembly, reducing labor time. Compatibility with the SMS series ecosystem simplifies spare parts sourcing and future upgrades, while RoHS/REACH compliance and UL94 V0 reduce regulatory risk and potential field failures, delivering lower maintenance costs over the system lifecycle.
Mechanical drawings and documentation are available through Eaton's resources; refer to the SMS series draw file BSA20040500201.pdf for detailed dimensions and mating information. This ensures accurate installation, compatibility checks, and correct harness design prior to procurement.
