FAQs
The SMS6SE4K9 uses a front-mount panel receptacle with a plug-and-mate approach. Align the 6-position PCB contacts with the mating pins on the board, then push the connector into the panel opening until the front face seats securely. Ensure the back housing is supported by the panel cutout and use appropriate strain relief to maintain insulation and vibration resistance. Pre-loaded contacts simplify initial assembly and reduce risk of misalignment.
This connector supports 6 PCB contacts with gold plating for low contact resistance and high corrosion resistance. It operates from -55 °C to 125 °C and carries IP30 protection. The RoHS-compliant plastic shell, plus UL94 V0 flammability rating, provides safety and regulatory compliance in harsh industrial environments, making it suitable for automated lines and control cabinets.
Yes. The Receptacle type with Front Mount Panel capability is specifically designed for compact control cabinets and panel assemblies. The 6-cavity layout and 6 contacts fit tight spaces while maintaining robust matings, and the push-pull coupling supports rapid, repeatable connections in high-cycle automation scenarios.
The connector is RoHS compliant and UL94 V0 rated for flame retardancy, with REACH considerations noted in its environmental specs. The IP30 rating provides a basic ingress protection level suitable for interior equipment. Together, these certifications support regulatory acceptance in many industrial sectors and ensure safer, compliant deployments.
The SMS6SE4K9’s gold-plated PCB contacts minimize contact resistance drift and corrosion over time, reducing maintenance intervals. Its quick mating and front-mount design speed assembly, lowering labor costs during initial wiring and field servicing. Overall, you gain improved reliability, lower downtime, and a shorter path to regulatory compliance in automation projects.
