Eaton SMS9H1 SMS Series Plastic Connector - 9-pole
Part Number: SMS9H1
Quick Summary
SMS9H1 is a 9-pole, quick-mating plastic rectangular connector designed for rugged industrial wiring in automation panels and machinery. Engineers often struggle with reliable mating and strain relief in tight harness layouts, leading to intermittent signals and cable damage. While certification details are not listed for this model, buyers typically verify CE marking, IP ratings, and SIL-related assurances for safety-critical installations with their Eaton supplier. By delivering a compact backshell strain-relief solution, SMS9H1 helps reduce assembly time, improve cabling integrity, and lower field maintenance costs, while supporting broad compatibility with SMS family components and existing panel hardware.

The 9-pole quick-mating design accelerates assembly and reduces downtime in production lines, delivering tangible efficiency gains as technicians can connect and disconnect harnesses rapidly without sacrificing reliability. The plastic shell keeps weight down and simplifies routing in crowded control panels, while maintaining necessary robustness for typical industrial environments. The strain relief backshell protects conductors from movement-induced wear and accidental pull-out, improving long-term reliability in vibration-prone machinery and mobile equipment. The SMS9H1 supports standard SMS family mating interfaces, enabling straightforward upgrades and spares consolidation, which lowers inventory costs and simplifies maintenance. The operating temperature range of -55 °C to 125 °C broadens applicability across cold rooms, hot cabinets, and outdoor enclosures, reducing the need for alternate housing. Installation benefits include available reference drawings (SE75800.pdf) to guide consistent, compliant mounting and wiring practices, and easy field serviceability when component wear occurs. In practice, these features translate to fewer field faults, faster repairs, and a lower total cost of ownership for automation panels and robotic workcells.

FAQs
SMS9H1 is designed to mate with other SMS family components, enabling seamless upgrades or repairs within SMS-based harnesses. Verify connector series, pin count, and keying to ensure full compatibility, and refer to the SE75800 drawings for mounting and routing guidance to prevent mis-mating or cable damage during installation.
The 9-pole arrangement supports multiple signals within a compact footprint, reducing harness length and simplifying routing in panels. To preserve signal integrity, keep conductors within recommended gauge, separate power and data lines where possible, and use the strain-relief backshell to minimize conductor movement during vibration or frequent disconnect/reconnect cycles.
Yes. With a -55 °C to 125 °C operating range and a plastic shell that keeps weight down, SMS9H1 is well-suited for demanding automation environments. The strain-relief backshell protects cables from wear in vibratory machinery, while the quick-mating design supports rapid field assembly and routine maintenance in control cabinets and robotic applications.
Certification details are not listed for SMS9H1; verify with Eaton for your region and application. When sourcing for regulated environments, confirm CE marking, IP-rated variants, and any SIL-related safety assurances from the supplier to ensure compliance in your specific installation.
Benefits accrue from faster mating, reduced maintenance due to strain-relief protection, and easier spare-part planning within the SMS family. In high-volume deployments, the ability to quickly assemble or service harnesses lowers labor costs, minimizes downtime, and simplifies inventory management by leveraging a common connector family across panels and machines.
