Eaton SMS4PH4TR29 Receptacle - Push-Pull IP30
Part Number: SMS4PH4TR29
Quick Summary
SMS4PH4TR29 is a quick-mating plastic rectangular connector for board-mounted signals in automation panels. In tight cabinets, misalignment and tool-heavy assembly slow projects and inflate labor costs. This SMS series part complies with UL94 V0 flammability and REACH, delivering safe, flame-retardant performance, while IP30 protection helps guard against dust in controlled environments. By combining a front-mount panel receptacle with tin pre-plated PCB contacts, it reduces assembly steps and improves reliability. For engineers sourcing compact, standard solutions, the SMS4PH4TR29 offers predictable compatibility with 4-way layouts and easy field maintenance, enabling faster prototyping and more consistent production throughput. This makes it a reliable, low-risk choice for high-mix manufacturing and automation projects.

4-position, 4-cavity layout keeps wiring tidy and minimizes PCB footprint, delivering a compact 4x position solution for board-mounted I/O. This arrangement reduces panel depth and simplifies routing, enabling tighter enclosure designs and faster assembly in control cabinets. For OEMs and integrators, the predictable pinout minimizes design rework when expanding a machine's IO frontage. In practical terms, it supports multi-channel sensors, actuators, and power/signal distribution with a single, standard connector family, reducing procurement complexity and spare-part inventory across automation projects. Push-Pull coupling delivers fast, repeatable mating with secure retention even in high-vibration environments. This reduces tool time during line changeovers and simplifies automated seaming in machine assemblies. For service teams, the ability to partner this connector with standard automation modules accelerates maintenance and minimizes downtime during product updates, migrations, and field upgrades across multiple lines. Tinned pre-plated PCB contacts provide reliable solderability and corrosion resistance, extending connector life in damp or dusty factories. The tin finish improves contact continuity over thousands of mating cycles, lowering field repair rates. This compatibility with common PCB practices supports straightforward rework and prototyping in automation labs and production lines. Front-mount panel receptacle design and compatibility with straight pin headers simplify installation and alignment. Clear panel cutouts and standardized 4x contact positions reduce misalignment risk, enabling faster commissioning. The IP30 rating, UL94 V0 flammability, and REACH compliance give users confidence when integrating into cabinets and machinery that demand safety and environmental responsibility while keeping enclosure sizes compact. Operating range -55 to 125 °C ensures consistent performance across manufacturing environments. The plastic shell delivers weight savings and electrical insulation, while the 4-contact arrangement supports a balanced mix of signal and small-duty power paths. This combination suits control panels, robotics interfaces, and automation modules where reliability matters most.

FAQs
SMS4PH4TR29 is specified as a straight-pin, front-mount panel receptacle with 4 contacts. It is designed for use with standard PCB headers and does not offer backshell options. When planning a mating pair, select compatible 4-position PCB headers and ensure correct alignment with the 4-cavity configuration to maintain reliable mating and ease of assembly in automated lines.
The connector is rated for a wide industrial range from -55 °C to 125 °C, supporting both cold-start conditions and hot-running equipment. This makes it suitable for harsh manufacturing environments, including automotive, packaging, and robotics applications where thermal cycling is common.
Yes. SMS4PH4TR29 is a front-mount panel receptacle with four male contacts positioned for 4-wide PCB layouts. Its IP30 protection class and tin-plated PCB contacts provide dependable performance in panel-mounted assemblies, while the Push-Pull coupling offers rapid mating, making it ideal for quick-change automation modules and prototype-to-production transitions.
Key certifications include UL94 V0 flammability and REACH compliance, with an IP30 protection rating. These certifications support safe operation inside electrical enclosures and align with common industry safety and environmental requirements for automation equipment.
Install as a front-mount panel receptacle on a 4-contact PCB with a straight-pin header. Ensure correct panel cutout alignment for reliable mating, and note that there is no backshell option for this part. Verify operating temperature range and environmental ratings (UL94 V0, REACH, IP30) to ensure suitability for your enclosure and process conditions.
