Eaton SMS3RE3TR29 SMS Series Connector - UL94 V0
Part Number: SMS3RE3TR29
Quick Summary
Eaton SMS3RE3TR29 is a compact PCB-mate receptacle for quick-mating connections in the Souriau SMS series. In tight panels, engineers struggle with space constraints, mating reliability, and long assembly times. Its IP30 protection, UL94 V0 flammability rating, and REACH compliance help meet safety, environmental, and regulatory requirements across industrial environments. This front-mount panel solution uses tin-plated PCB contacts and a durable plastic shell to reduce weight and cost. The design supports fast, error-free installations in automation cabinets, control panels, and equipment in energy, water, and factory automation sectors.

Feature → Business Impact → Application: Three-position, front-mount panel receptacle consolidates three electrical contacts into a compact footprint, reducing panel depth and wiring complexity. The result is a lighter, more efficient assembly with fewer part counts, ideal for dense control cabinets and equipment where space is at a premium. Feature → Business Impact → Application: Push-Pull coupling enables quick mating and unmating, minimizing maintenance downtime and mis-mating risk. In production lines, technicians connect or service channels rapidly without tools, supporting faster changeovers in packaging lines and robotics cells. Feature → Business Impact → Application: Tin pre-plated PCB contacts provide reliable electrical performance and corrosion resistance, extending service life in humid or dusty environments, which lowers maintenance costs and downtime in harsh manufacturing floors. Feature → Business Impact → Application: Operating temperature range of -55 to 125 °C and IP30 protection ensure dependable operation in challenging environments, reducing enclosure needs and replacements in automotive, energy, and process automation. Feature → Business Impact → Application: Lightweight plastic shell and compact dimensions (13.4 mm length, 16.2 mm height, 5.9 mm width) simplify cable routing and panel aesthetics, enabling more compact equipment and easier installation in space-constrained control panels.

FAQs
To install the SMS3RE3TR29 in a panel, verify the front-mount panel cutout matches the 16.2 mm height and 13.4 mm depth, then align the receptacle with the PCB and insert until seated. The push-pull coupling enables rapid mating and unmating, reducing time on maintenance or field changes. After seating, confirm IP30 protection is maintained and the 3 PCB contacts are engaged.
SMS3RE3TR29 uses PCB contacts in a three-position receptacle designed for direct PCB termination. Tin pre-plated contacts provide reliable, corrosion-resistant connections, while the front-mount design and 13.4 mm depth support compact PCB layouts. Its 3-contact configuration is ideal for compact automation modules, instrumentation panels, and space-constrained control systems.
The SMS3RE3TR29 is designed for industrial environments with IP30 protection and UL94 V0 flammability rating, ensuring safe operation in dusty or conductive settings. It operates from -55 °C to 125 °C, and complies with REACH. These certifications and operating ranges help you meet regulatory requirements while maintaining performance in harsh manufacturing or energy applications.
SMS3RE3TR29 is a front-mount panel receptacle within the SMS series and is designed to mate with corresponding SMS plug assemblies that share identical contact layouts and coupling mechanisms. Always verify mating interface compatibility and avoid using non-compatible backshells, as this model explicitly indicates no backshell option is available.
Choosing SMS3RE3TR29 delivers a lower total cost of ownership through reduced panel footprint, lightweight plastic housing, and 3-contact efficiency that minimizes wiring complexity. The push-pull coupling reduces maintenance time, while tin-plated PCB contacts improve longevity in demanding environments. Together, these factors translate to faster assemblies, less downtime, and predictable performance in space-constrained automation projects.
