With a 4-pole configuration, the SMS4H1 enables multiple circuits in a single plug, reducing harness complexity and panel space. This consolidation lowers part counts and simplifies inventory, delivering cost savings and quicker field deployments in automation projects. The strain-relief backshell protects cables from bending at the interface, lowering wear, extending connector life, and reducing downtime during service. The plastic shell keeps the assembly lightweight and cost-effective while providing reliable electrical insulation in standard industrial settings, supporting safer and easier installation in control cabinets and equipment housings. Operating from -55 °C to 125 °C ensures consistent performance across cold starts and hot factory floors, minimizing rework in temperature-variant environments and enabling robust robotics and process control connections. Quick-mating design reduces assembly time on production lines, improving throughput and reducing commissioning delays, which is especially valuable for high-mix production or OEM harness builds. Compatibility with the SMS series streamlines procurement, testing, and maintenance, while the included Eaton Souriau drawings SE75800 provide exact mating and installation guidance, improving first-time fit and system integration.
