Eaton SMS4SE3T Receptacle Connector - IP30 Push-Pull
Part Number: SMS4SE3T
Quick Summary
Eaton SMS4SE3T is a quick-mating receptacle connector for compact PCB and front-panel assemblies. In tight spaces, engineers confront misalignment, insertion effort, and repeated mating failures that slow production. The design integrates IP30 protection, UL94 V0 flammability, and REACH compliance to meet harsh industrial standards. With tin pre plated PCB contacts, a 4-contact layout, and a push-pull coupling option, it reduces assembly time, improves reliability, and lowers lifecycle costs. The compact footprint and front-mount panel receptacle design support scalable, cost-efficient deployments across control panels and automation equipment.

Feature → Business Impact → Application: 4-contact, front-mount panel receptacle with a 13.4 mm depth, 21.3 mm height, and 5.9 mm width delivers a compact footprint that minimizes harness length and system volume, reducing overall cabinet size and installation time. This translates to faster assembly, simpler cable routing, and lower labor costs in control panels and automated equipment that demand reliable signal integrity. The Push-Pull coupling provides one-handed mating and secure retention in vibration-prone environments, improving uptime and reducing maintenance interruptions in manufacturing lines and packaging systems. Tin pre plated PCB contacts offer corrosion resistance and stable electrical performance, extending connector life in harsh environments while supporting consistent solderability and reworkability during assembly. IP30 protection, UL94 V0 rating, and REACH compliance reinforce regulatory confidence for industrial applications, ensuring safe operation across machinery and robotics workplaces. End-user benefits include predictable mating cycles, reduced field service calls, and streamlined BOMs due to standardized SMS series components, enabling faster time-to-value for machine builders and system integrators.

FAQs
The SMS4SE3T is a 4-contact front-mount panel receptacle designed for PCB integration. Begin by aligning the receptacle with the panel cutout, ensuring the 4 contacts align with the PCB traces. Insert the connector firmly until the front face seats against the panel, then engage the Push-Pull coupling to secure mating. The no backshell configuration simplifies installation, reduces BOM complexity, and speeds field servicing while maintaining IP30-rated protection and reliable contact performance for 4-circuit wiring.
Tin pre plated PCB contacts provide reliable solderability and corrosion resistance, essential for long-term signal integrity in industrial environments. The SMS4SE3T’s 4-contact layout with tin-plated sockets ensures consistent contact pressure and repeatable mating, which translates to predictable electrical performance and reduced maintenance. This is particularly important in tight control panels where vibration and temperature cycling can challenge connector reliability.
Yes. The SMS4SE3T meets IP30 protection, offering enclosure protection against solid objects while limiting exposure to liquids, and it carries UL94 V0 flammability rating for plastics, along with REACH compliance. These certifications support safe operation in industrial settings, enable compliance with internal standards, and simplify risk assessment for control cabinets, robotics, and automation assemblies.
Absolutely. The SMS4SE3T is explicitly a front Mount Panel receptacle with a 4-contact (4-cavity) configuration. Its Push-Pull coupling supports quick and reliable mating in panel-mounted deployments, while tin pre plated contacts and plastic shell optimize weight and routing in compact control panels used in machines, conveyors, and packaging lines.
Adopting the SMS4SE3T can reduce cycle time through faster mating thanks to Push-Pull coupling, decrease maintenance calls due to reliable IP30-rated protection and corrosion-resistant tin contacts, and simplify BOMs with a standardized 4-cavity SMS series part. In high-mix automation environments, these advantages translate to lower labor costs, reduced downtime, and faster time-to-value on new line installations and retrofits.
