Eaton SMS4R1 Receptacle - IP30
Part Number: SMS4R1
Quick Summary
The Eaton SMS4R1 receptacle delivers quick mating for compact panel-mounted connections in industrial automation. Engineers often struggle with space constraints, wiring reliability, and tool-free mating in harsh environments. This design meets RoHS and REACH expectations and offers UL94 V0 flame rating with IP30 protection. By combining a lightweight plastic shell with a 4‑cavity push‑pull interface, it translates to faster assembly, lower maintenance, and reliable performance in control panels and automation gear. As a result, procurement gains predictable lead times and reduced total cost of ownership. This makes SMS4R1 a compelling choice for space-constrained control cabinets, sensor networks, and automation enclosures. With robust RoHS and REACH compliance, it helps meet sustainability goals too.

SMS4R1 is a front-mount panel receptacle from Eaton's Souriau SMS series, designed for four-position quick mating in compact spaces. Feature: four crimp contacts and four cavities reduce wiring complexity and harnessing time, delivering tangible efficiency gains on assembly lines and in control cabinets. Business impact: shorter commissioning times and fewer harness-related faults. Application: ideal for space‑constrained automation panels where reliability and speed matter. Feature: push-pull coupling enables tool-free mating with positive retention. Business impact: reduces maintenance downtime and simplifies field service. Application: machine enclosures and sensor housings requiring fast field connections. Feature: lightweight plastic shell (approx. 3 g) and compact footprint (25 mm length, 21.2 mm width, 15.2 mm height). Business impact: lowers panel weight, enables higher-density mounting, and frees cabinet space. Application: dense control panels and compact automation modules. Feature: IP30 protection and operating range from -55 °C to 125 °C. Business impact: predictable performance in harsh environments and broad industrial deployments. Application: machinery operating in temperature extremes. Feature: RoHS, REACH, and UL94 V0 compliance. Business impact: simplifies regulatory approvals and sustainability reporting. Application: industrial and automotive-grade installations. Feature: no backshell option; front-mount panel design simplifies integration. Business impact: reduces accessory inventory and simplifies installation planning. Application: panels where backshell customization is not required. Feature: contact delivery not included; crimp contacts must be sourced separately. Business impact: enables flexible procurement and tailored terminal selection. Application: systems demanding specific crimp terminals and supply chain control.

FAQs
SMS4R1 is a front-mount receptacle with four cavities and four crimp contacts. Its compact 25 mm depth and overall small footprint simplify panel routing and harness design, while the absence of a backshell option requires planning for direct-panel mating. Ensure mating alignment with the panel cutout and verify crimp terminal compatibility for reliable electrical connections.
The SMS4R1 operates from -55 °C to 125 °C and carries IP30 enclosure protection. It is RoHS and REACH compliant with UL94 V0 flame rating, making it suitable for broad industrial environments and equipment requiring regulatory compliance and flame resistance in plastic housings.
Yes, SMS4R1 uses crimp contact delivery. Terminals must be sourced separately and matched to the four cavities. Use proper crimp tooling and inspection to ensure reliable contact retention and electrical performance, minimizing the risk of poor termination in high-vibration environments.
SMS4R1 suits space-constrained control cabinets, sensor networks, and automation enclosures where four signal or small power lines can be routed through a panel mount receptacle. Its push-pull coupling accelerates mating, while the IP30 rating and RoHS/REACH compliance support durable, regulatory-aligned installations in industrial environments.
SMS4R1 carries RoHS and REACH compliance and a UL94 V0 flammability rating, along with IP30 protection. These certifications help meet industry and regional regulatory requirements, simplify supplier qualifications, and support sustainability goals in automation projects.
