FAQs
The SMS9RDH3 is part of the Eaton Souriau SMS series and is designed as a 9-position receptacle that mates with corresponding SMS9 plug components. It uses crimp contacts and a strain-relief backshell. For proper compatibility, pair with the matching SMS9 series plug and ensure mating alignment is preserved during assembly to maintain IP40 protection and reliable crimp connections.
The SMS9RDH3 provides 9 crimp contacts in a free-hanging receptacle configuration. It operates from -40 °C to 105 °C, with an IP40 rating for basic dust protection and incidental contact. It adheres to RoHS and REACH requirements and features UL94 V0 flame resistance, making it suitable for demanding industrial environments.
This connector is tailored for industrial automation and machine wiring, including control panels, conveyors, and robotics. While robust for factory floors, it is not a watertight solution. Use in indoor or sheltered outdoor environments where IP40 protection and a 9-pin, quick-mating arrangement meet your installation and maintenance needs.
SMS9RDH3 carries RoHS and REACH compliance, with a UL94 V0 flame rating. These certifications ensure material safety, environmental compliance, and flame resistance for use in controlled industrial installations and assemblies that require regulatory adherence.
Key ROI drivers include the integrated strain-relief hood that reduces cable stress and extends harness life, plus a push-pull quick-mating system that speeds assembly and reduces downtime. Its compact footprint and 9-contact configuration support dense harnessing, lowering cabinet space requirements and simplifying field upgrades or repairs.
