Eaton SMS4RDH1 Receptacle - Plastic Push-Pull IP30
Part Number: SMS4RDH1
Quick Summary
SMS4RDH1 is a quick‑mating plastic rectangular connector for industrial control panels and cable assemblies. When panel space is tight or vibration is present, engineers need reliable mating without complex setup. It carries IP30 protection, UL94 V0 flammability, and RoHS/REACH compliance for safe, compliant installations. The design combines a compact 4‑cavity footprint with Push‑Pull coupling and integrated strain relief, delivering faster assembly, reduced maintenance, and lower downtime for high‑demand automation applications.

FAQs
SMS4RDH1 uses crimp contact delivery and supports four contacts within a 4‑cavity layout. It is designed to work with standard Souriau SMS crimp terminals, enabling consistent termination and reliable strain relief. When selecting mating components, verify cable gauge and crimp tooling to ensure proper compression and long‑term retention in the free hanging receptacle.
Install SMS4RDH1 as a free hanging receptacle with the integrated strain relief hood engaged. Use the Push-Pull coupling for mating and unmate quickly during maintenance. Since contact delivery is not included, source the compatible crimp contacts separately and ensure correct crimp height and conductor insulation fit to preserve IP30 rating and mechanical integrity.
SMS4RDH1 operates from -55 °C to 125 °C, suitable for harsh industrial environments. It holds UL94 V0 flammability rating and complies with RoHS and REACH directives, supporting safe operation with restricted substances and regulatory compliance in many automation applications.
Yes. The Push-Pull coupling provides secure mating, and the integrated strain relief helps absorb cable movement, reducing contact wear. With IP30 protection and a compact 4‑cavity footprint, it maintains reliable connections in vibrating machinery and automated lines.
