Eaton SMS4P1 Quick Mating Plastic Connector - IP30
Part Number: SMS4P1
Quick Summary
SMS4P1 is a quick mating plastic connector designed for reliable harness interconnects in industrial automation. Engineers often face slow mating and mismatched parts in tight control panels, which drives costly downtime. It delivers RoHS and REACH compliance, UL94 V0 flame rating, and IP30 protection to meet safety and regulatory requirements. Placed in the Souriau SMS series family, it supports standard crimp contacts and modular mating with minimal assembly steps. The result is faster deployments, predictable maintenance, and lower total cost of ownership for panel wiring and robotic integrations.

The SMS4P1 uses a compact 4-position layout with a 32.9 mm length, 23.7 mm width, and 17.8 mm height, yielding a lightweight 4.1 g housing that minimizes panel footprint and wiring complexity. This translates to easier routing in crowded control cabinets and reduced weight on high-speed machinery, improving reliability in dynamic environments. The Push-Pull coupling delivers fast, secure mating with robust retention, which cuts installation time and minimizes vibration-induced disconnects in robotic arms and conveyors. Crimp contacts are compatible, offering a flexible supply chain, though contact delivery is not included, so plan to source matching 4-position crimp fittings to ensure precise, repeatable terminations. Environmental resilience is guaranteed by IP30 protection and an operating range from -55 °C to 125 °C, plus UL94 V0, RoHS, and REACH compliance, enabling safer operation in diverse industrial settings. The plastic shell reduces weight further and supports non-backshell configurations, aligning with streamlined harness designs for control panels and machine-to-machine interfaces. Overall, SMS4P1 delivers a low total cost of ownership by combining lightweight construction, fast mating, and regulatory compliance within the compact SMS series ecosystem.

FAQs
SMS4P1 uses crimp contacts and a straight plug with a push‑pull coupling; contact delivery is not provided, so you must source compatible 4‑position crimp contacts that fit the SMS4P1 cavities. Verify tooling and crimp specifications, ensure proper polarization, and follow established mating procedures to prevent misalignment or poor contact retention in vibration-prone environments.
SMS4P1 operates from -55 °C to 125 °C and carries an IP30 protection rating. It is certified with UL94 V0 flammability and RoHS/REACH compliance, providing suitable safety margins for indoor industrial environments and standard regulatory expectations for electrical connectors used in control panels and machinery.
Yes. The 4-position, straight plug design with Push-Pull coupling and low weight (4.1 g) makes it ideal for robotics harnesses and compact control panels. Its compact footprint and reliable crimp connections support quick, repeatable assemblies in space-constrained enclosures, while meeting industry standards for safety and environmental compliance.
SMS4P1 is RoHS and REACH compliant, features UL94 V0 flame rating, and offers IP30 protection. These certifications ensure regulatory compliance for safe, durable operation in electrical cabinets, machine wiring, and industrial automation applications.
The design minimizes panel space and weight, enabling easier routing and faster assembly. Push-Pull mating reduces downtime during maintenance, and the absence of an integrated backshell simplifies part counts in streamlined harnesses. While contacts must be sourced separately, standard crimp fittings provide flexibility and long-term cost efficiency for maintenance and field upgrades.
