Feature is a quick-mating push-pull connector that accelerates assembly and reduces misalignment risk during panel wiring. Business impact is a measurable decrease in wiring time and improved production line throughput, especially in high-mix, low-volume environments where changeovers are frequent. Application: ideal for control panels and automation equipment that require rapid, secure PCB-to-cable connections without complex backshells. Feature is a 3-contact receptacle with front-mount panel integration and short PCB female contacts, enabling a compact footprint and straightforward PCB layout. Business impact includes simplified BOMs and predictable connector behavior across three signal paths, which translates to lower installation risk and faster debugging in industrial automation projects. Application: suitable for multi-signal boards and compact controller assemblies. Feature is tin pre-plated PCB contacts with push-pull coupling for reliable mating and corrosion resistance. Business impact includes long-term contact integrity and reduced maintenance costs over the life of the equipment. Application: common in harsh industrial environments where moisture and contaminants are present. Feature is IP30 protection with an operating range from -55 to 125 °C and a plastic shell, delivering lightweight, resilient performance. Business impact includes compliant operation under extreme temperatures and safe handling in automated systems. Application: critical for outdoor or heat-intensive control panels. Feature is a front-mount panel receptacle with a 3-layout, 3-contact configuration and no backshell option, simplifying installation and reducing accessory costs. Business impact includes lower inventory complexity and faster panel assembly. Application: compatible with streamlined automation harnesses and modular panel designs. Feature is a compact 13.4 mm depth, 16.2 mm height, and 5.9 mm width, totaling a 2.5 g weight, which supports space-constrained installations. Business impact includes weight reduction and easier routing in dense control enclosures. Application: well-suited for compact robot cells and machine control panels.

FAQs
SMS3SE3T is designed as a straight boardmount receptacle with short PCB female contacts in the 3-position SMS series. It fits front-mount panel configurations and pairs with standard 0.1 inch (2.54 mm) pitch style footprints on compatible PCBs. Its tin-plated PCB contacts ensure reliable solder joints, while the front-mount design keeps wiring simple and accessible during assembly and servicing.
The push-pull coupling on SMS3SE3T provides a fast, guided mating action that reduces misalignment and the need for aligning mechanical features during installation. This translates to faster connect/disconnect cycles, lower labor costs, and improved rework resistance in high-volume automation lines where quick panel changes are common.
Yes. SMS3SE3T is a front-mount panel receptacle with a compact footprint (13.4 mm depth, 16.2 mm height, 5.9 mm width) and a 3-contact layout. Its IP30 rating and tin-plated PCB contacts provide dependable operation in enclosed control cabinets, while the absence of a backshell option reduces accessory requirements and inventory impact.
SMS3SE3T supports a UL94 V0 flammability rating and IP30 protection, with REACH compliance for chemical safety. These specifications help ensure flame retardancy, basic ingress protection in non-dusty environments, and regulatory alignment for European and global deployments in automation equipment.
The combination of quick-mating action, front-mount panel compatibility, and three-contact PCB sockets reduces assembly time and field service complexity. Tin-plated contacts improve long-term reliability, while the lightweight plastic shell lowers harness weight. Collectively, these features can shorten installation cycles, reduce downtime, and lower total cost of ownership in mass-produced automation systems.
