Eaton SMS3PH3TR29 SMS Series Connector - IP30
Part Number: SMS3PH3TR29
Quick Summary
SMS3PH3TR29 is a compact quick-mating plastic rectangular connector designed for rugged industrial panel and board mounting. In environments where space is at a premium, engineers often battle bulky, hard-to-mate solutions that slow assembly and risk misalignment. This device addresses those challenges with a tight footprint and reliable mating action. It carries critical certifications such as UL94 V0 flammability, REACH compliance, and IP30 protection, supporting safety, regulatory, and environmental requirements. Built as a front-mount panel receptacle with a 3-pin PCB-ready contact layout, it delivers straightforward installation and long-term reliability. The combination of Tin pre-plated contacts, push-pull coupling, and a plastic shell supports fast field maintenance, cost control, and scalable deployment across applications.

FAQs
Install SMS3PH3TR29 as a front-mount panel receptacle by aligning the 3 PCB contacts with the board pads and seating the connector into the panel opening. Solder or press-fit the PCB contacts as per your assembly method, then mate with the corresponding plug using the push-pull action. Ensure correct orientation and verify full engagement before powering the system.
The SMS3PH3TR29 combines IP30 protection with UL94 V0 flammability rating and REACH compliance, delivering safe operation and regulatory peace of mind. Its tin pre-plated contacts resist corrosion, and the plastic shell accommodates broad operating temperatures from -55 °C to 125 °C, making it reliable in factory floors, machinery cabinets, and robotics.
Key certifications include UL94 V0 flammability, IP30 protection, and REACH compliance. UL94 V0 ensures flame retardancy for safety in electrical components, IP30 provides protective performance against solid objects, and REACH ensures materials meet environmental and health standards—critical for automotive, machinery, and automation applications.
SMS3PH3TR29 is designed as part of the SMS series with front-mount panel receptacle characteristics and push-pull mating. The connector accessory option specifies no backshell possibility, so compatibility with backshells is not supported. For multi-part assemblies, ensure mating connectors come from the SMS family and match the 3-contact, PCB-ready configuration.
ROI benefits stem from faster mating cycles due to push-pull coupling, reduced assembly time with a compact front-mount design, and fewer maintenance events thanks to robust IP30 protection and tin-plated contacts. In high-mix, high-volume automation lines, these factors translate to lower labor costs, shorter downtimes, and improved overall equipment efficiency.
