Eaton SMS3RE4S6 Plastic Rectangular Connector - IP30
Part Number: SMS3RE4S6
Quick Summary
Eaton SMS3RE4S6 is a plastic rectangular connector for quick mating on PCB-mounted control panels. In dense panel layouts, misalignment and slow mating can derail schedules; this design minimizes those risks by providing a reliable, easy-to-connect interface. It carries RoHS and REACH compliance, UL94 V-0 flammability, and IP30 protection, helping you meet regulatory and safety requirements. Tied to the Souriau SMS series, it supports front-mount panel receptacles, tin-plated PCB contacts, and a compact 3-contact layout for cost-efficient automation. This combination delivers predictable mating performance and reduced field service costs in industrial automation and control equipment.

FAQs
To install the SMS3RE4S6, align the 3-contact PCB receptacle with the panel cutout designed for the SMS series, insert it straight, and push until the push-pull coupling closes with a distinct mate feel. Verify the mating alignment, ensure the panel interface is clean, and confirm the IP30 seals engage properly. No backshell accessory is included, so plan cable routing accordingly.
Key specs to verify include IP30 protection, operating temperature range from -55 to 125 °C, RoHS and REACH compliance, and UL94 V-0 flammability. Confirm the connector is loaded with PCB contacts and that the front-mount panel receptacle geometry matches your panel cutout and cavity layout (3 cavities in this model).
The SMS3RE4S6 is designed as a 3-contact front-mount receptacle within the Souriau SMS series. Compatibility is best confirmed by cross-referencing the catalog number SMS3RE4S6 with your SMS mating partners in the same series. For detailed mating diagrams, refer to the accompanying BSA20306600200.pdf drawings linked in the Eaton resources.
No, the SMS3RE4S6 specification notes no backshell possibility. If shielding or a backshell is required for additional cable protection or EMI considerations, evaluate a different SMS variant or consider an external shielding solution that accommodates your enclosure design and routing constraints.
By delivering quick mating with a compact 3-contact layout, the SMS3RE4S6 reduces assembly and maintenance time, lowering labor costs in panel builds. Its IP30 rating and RoHS/REACH compliance support regulatory adherence, while tin-plated contacts offer long-term reliability, potentially decreasing field failures and service intervals in repetitive automation applications.
