FAQs
The SMS6R3 is a front-mount panel receptacle with a 6-position arrangement, designed for compact control panels. Its push-pull coupling and crimp contacts simplify wiring harness assemblies, reduce panel space usage, and speed installation in automated machines, conveyors, and robotic interfaces.
Rated from -40 °C to 105 °C, the SMS6R3 maintains electrical integrity across thermal cycling common in manufacturing environments. The plastic shell is flame-retardant (UL94 V0) and RoHS/REACH compliant, supporting reliable operation in high-temperature manufacturing zones and automatic machinery.
Yes. The SMS6R3 is part of the Eaton Souriau SMS series and features a standard 6-position layout with a front-mount receptacle. It uses crimp contacts and a push-pull coupling, aligning with common Souriau family dimensions and installation practices while allowing straightforward harness integration.
The SMS6R3 includes RoHS and REACH compliance, along with UL94 V0 flame retardant rating. These certifications support regulatory alignment for worldwide deployments, reducing compliance risk in global supply chains and helping meet safety and environmental standards in industrial equipment.
The SMS6R3 delivers faster assembly due to quick-mating crimp connections and a compact 25 mm length, which reduces panel space and wiring complexity. Lightweight design lowers overall harness weight, contributing to energy efficiency and serviceable lifecycle improvements, with potential reductions in labor time and maintenance downtime.
