The SMS9R3 features a nine-position, 25 mm deep rectangular connector design that maximizes circuit density while minimizing panel footprint, enabling cleaner harness routing in crowded control cabinets. This translates to faster assembly, reduced risk of miswiring, and easier field maintenance in high-mix production lines. The push-pull coupling provides quick mating with consistent retention, lowering commissioning time and boosting uptime in automated systems. Its flame-retardant plastic shell, UL94 V0 rating, and RoHS compliance deliver safety and regulatory assurance across global deployments, supporting quality programs and reducing compliance-related rework. With a front-mount panel receptacle and crimp contacts, installation is straightforward and vibration-resistant, ideal for machines with frequent panel access or modular cabinet designs. The no-backshell option simplifies procurement and inventory management while still delivering robust protection, and the IP40 rating offers reliable basic ingress protection in indoor industrial environments. Operating from -40 °C to 105 °C, the SMS9R3 maintains performance in extreme conditions typical of manufacturing floors and outdoor enclosures. The compact 9-contact layout supports scalable interconnects for evolving machinery and allows consistent cross-model compatibility within the SMS family, which helps engineers standardize components across projects and reduce training time for technicians.

FAQs
Yes, the SMS9R3 uses crimp contact delivery and is designed for straightforward crimp-terminals within a 9-position layout. There is no backshell option available for this model, as specified by the product data. To protect the connection, use proper strain relief on the harness and ensure correct mating alignment during panel installation.
The SMS9R3 is IP40 rated, has UL94 V0 flame retardancy, and complies with RoHS and REACH. It operates reliably from -40 °C to 105 °C, making it suitable for harsh industrial environments and global deployment in automation, packaging, and robotics applications.
A nine-position, 25 mm depth design concentrates nine circuits in a compact footprint, freeing panel space and simplifying cable routing. This enables higher channel density in control cabinets and supports scalable wiring schemes for evolving automation projects, reducing enclosure size without sacrificing interconnect reliability.
Plan for a front-mount panel receptacle with crimp contacts and no backshell, as indicated. Ensure correct crimp terminals are used, verify alignment before mating, and allow for appropriate strain relief and cable management. Consider enclosure ingress protection needs and operating temperature ranges when selecting mounting locations inside equipment cabinets.
Industries such as industrial automation, machine building, packaging, and robotics benefit from the SMS9R3 due to its compact 9-position design, reliable push-pull mating, and robust safety certifications. It supports dense interconnects in control panels, improves installation efficiency, and helps standardize connectors across projects for easier maintenance and faster ROI.
