Feature: Push-Pull coupling enables fast, secure mating with minimal torque and misalignment risk. Benefit: Reduces installation time and rework in panel assemblies, improving overall line throughput. Application: Ideal for control cabinets and automated machines where quick field mate/demate cycles are required and downtime must be minimized. Feature: Front-mount panel receptacle with a 3-position layout provides a compact footprint. Benefit: Saves panel space and simplifies routing in dense electrical enclosures, enhancing reliability in robotics and packaging lines. Application: Suited for PCB-to-panel transitions in space-constrained automation environments. Feature: Gold & Tin plated PCB contacts and a plastic shell keep weight low while maintaining corrosion resistance. Benefit: Extends component life in harsh environments and lowers total cost of ownership through fewer maintenance cycles. Application: Used in variable-speed drives, sensors, and I/O modules in industrial automation. Feature: Environmental and safety compliance include UL94 V0, RoHS, and REACH. Benefit: Helps you meet global regulatory requirements without extra certification costs. Application: Critical for machinery destined for regulated markets. Feature: No backshell option reduces parts count and simplifies sourcing. Benefit: Lowers assembly complexity and procurement lead times while maintaining core protection with IP30. Application: Suitable for controlled environments where external shielding is added separately.

FAQs
SMS3RE3S6 features a 3-contact PCB receptacle arrangement designed for straight board-mount applications with long PCB female contacts, enabling reliable electrical connections on standard PCBs. Its front-mount panel receptacle type simplifies integration into control panels, aligning with the Souriau SMS series. This combination supports quick field mating and a compact payload, making it suitable for tight automation enclosures and space-constrained instrumentation.
The connector carries a UL94 V0 flammability rating and is RoHS and REACH compliant, ensuring materials and finishes meet harsh industrial safety and environmental standards. IP30 protection indicates basic protection against solid contaminants. These certifications support compliance in a wide range of industrial environments, including robotics, packaging, and process automation.
No backshell option is listed for this model. The absence of a backshell reduces parts count and sourcing complexity, which can streamline installation in clean, open panels. If shielding or additional protection is required, it must be provided externally or through enclosure design, while still leveraging the connector's front-mount receptacle interface and push-pull coupling for fast mating.
Push-Pull coupling offers rapid, tool-free mating with repeatable engagement, minimizing setup time during commissioning and maintenance. In automation environments, this translates to lower downtime, easier field servicing, and improved vibration resistance compared to snap-fit alternatives. It is particularly advantageous for modular panels, machine stops, and intermittent access points in conveyors and assembly lines.
Ensure alignment with the front-mount panel receptacle design and respect the 3-contact layout and 13.4 mm x 16.2 mm footprint. Maintain operating temperatures within -55 °C to 125 °C and avoid exposure beyond IP30 environments unless additional enclosure protection is provided. Use RoHS/REACH-compliant materials and verify mating cycles meet your equipment’s lifecycle expectations to maintain reliability in harsh industrial settings.
