Eaton SMS3RE4TR29 Quick Mating Connector - IP30
Part Number: SMS3RE4TR29
Quick Summary
The Eaton Souriau SMS3RE4TR29 quick mating plastic rectangular connector enables fast PCB-to-board connections in compact enclosures. Engineers often contend with misalignment, lengthy mating cycles, and limited space that slow deployment. The design carries IP30 protection with UL94 V0 flammability and REACH compliance, supporting robust, regulator-ready operation. Its front-mount receptacle for three PCB contacts reduces wiring complexity, while tin-plated contacts improve longevity. Together with push-pull coupling and compact dimensions, it supports efficient manufacturing and reliable service in automation and controls. For procurement teams, the consistent 3-contact configuration and loaded contact delivery streamline stocking and reduce spare-part variety. In practice, engineers value the material compatibility and predictable performance across -55 to 125 °C environments.

FAQs
SMS3RE4TR29 is a three-contact, front-mount panel receptacle from the Eaton Souriau SMS series designed for quick mating in compact assemblies. The unit features a 3-contact PCB interface with loaded contacts, push-pull coupling, and tin-plated finishes on the PCB side. It is intended for PCB-to-panel interconnects in control cabinets, machine enclosures, and sensor modules where space is limited and reliability is critical.
Key specs include 3 contacts across 3 cavities, a front-mount panel receptacle, 13.4 mm length, 16.2 mm height, 5.9 mm width, and a weight of 2.7 g. The contact is tin pre-plated for durability, and the device uses a push-pull coupling with IP30 protection. Operating temperature ranges from -55 °C to 125 °C, with plastic shell material.
Yes, SMS3RE4TR29 carries IP30 protection, indicating protection against solid objects larger than 2.5 mm but no protection against liquids. This makes it suitable for internal uses inside equipment enclosures and control panels where environmental exposure is limited. For installation, plan for panel cutouts that accommodate the 16.2 mm height and 5.9 mm width, and note that no backshell accessory is available.
Consider that SMS3RE4TR29 is a front-mount panel receptacle with straight boardmount contacts and loaded delivery. There is no backshell accessory, which simplifies BOMs but limits added protection against dust or mechanical wear. Ensure correct panel thickness and cutout alignment to maintain IP30 integrity, and use matching mating connectors in the SMS family to guarantee continuity and performance in automated sequences.
Ideal for industrial automation, control panels, robotics interfaces, and sensor modules, the SMS3RE4TR29 enables faster assembly, reduced error rates, and easier field maintenance due to its pull-coupled mating and loaded contacts. The durable tin plating and temperature range support longer service life, lowering spare-part costs. In high-mix environments, the standardized SMS series reduces parts variety while improving supplier consolidation and procurement efficiency.
