The 9-position layout with crimp contacts enables dense wiring without sacrificing reliability, reducing panel size and assembly time. This translates to higher channel density and faster harnessing, improving machine throughput and lowering labor costs in production lines. In addition, the push-pull coupling provides quick mating and repeatable connections, minimizing field downtimes and reducing torque load on the housing for longer component life and easier reconfigurations. The IP40 rating combined with a flame-retardant plastic shell enhances safety and enclosure integrity, supporting compliance and reducing the risk of arc-related incidents in industrial cabinets. With a free-hanging receptacle and no backshell option, installation is simplified in tight spaces while keeping total cost of ownership in check. Operating from -40 to 105 °C, the SMS9RD3 maintains performance across harsh environments, ensuring reliable automation in temperature-variant facilities. The lightweight plastic shell (6.34 g) contributes to easier handling and wiring pull during assembly and maintenance in high-murface-density panels.

FAQs
SMS9RD3 fits as a 9-position receptacle within the Souriau SMS series, using crimp contacts and a push-pull mating method for rapid field assembly. Its free-hanging receptacle design avoids backshell requirements, simplifying routing in tight enclosures. Ensure alignment with the 9-cavity layout, verify correct crimp tooling, and follow standard panel cutouts to preserve IP40 protection and mechanical stability.
SMS9RD3 provides nine crimp contacts in a 9-position layout with a compact footprint of 32.9 mm by 18.5 × 18.6 mm and a weight of 6.34 g. It is IP40-rated, operates from -40 °C to 105 °C, and is UL94 V0 flame-retardant with RoHS compliance. This combination supports reliable operation in demanding industrial environments while meeting regulatory requirements.
Yes. The SMS9RD3 is designed for control panels, robotics, and automation lines where space is at a premium and quick field mating is valuable. The 9-position configuration supports multiple signal and small power lines, while the push-pull coupling and free-hanging receptacle simplify reconfiguration and maintenance in dynamic manufacturing lines.
SMS9RD3 carries UL94 V0 flame retardancy and RoHS compliance, with fire & smoke performance noted in its environmental specifications. The IP40 rating provides basic ingress protection suitable for interior cabinet use, helping meet common industrial safety and environmental requirements across many automation environments.
Benefits include reduced downtime due to quick mating and straightforward removal for servicing, as well as lower labor costs from simplified installation. The crimp contacts and compact form factor facilitate rapid cable harnessing, while RoHS and RoHS-compliant materials minimize regulatory risk. Plan for periodic inspection of contact crimps and verify mating alignment to preserve longevity in high-cycle automation scenarios.
