FAQs
The SMS4RE3TR29 is a front-mount panel receptacle in the Souriau SMS series designed for PCB interconnects. It features four tin-plated PCB contacts, a push-pull coupling, and a compact 13.4 mm depth with a 5.9 mm width and 21.3 mm height. It is intended for front-panel mounting in protected enclosures and is compatible with standard board-mounted assemblies.
SMS4RE3TR29 provides four PCB contacts loaded for immediate use, tin-plated for solderability and corrosion resistance. It carries an IP30 protection rating, operates from -55 °C to 125 °C, and uses a plastic shell with UL94 V0 flammability and REACH compliance. These specs support reliable performance in controlled industrial environments and align with typical control-panel requirements.
Yes. The SMS4RE3TR29 is a front-mount panel receptacle designed for control cabinets and similar enclosures. Its front-mount panel receptacle type, compact 4-position layout, and push-pull mating streamline assembly and service. With IP30 protection and tin-plated PCB contacts, it tolerates vibration and temperature swings common in industrial settings while keeping wiring tidy and accessible.
SMS4RE3TR29 carries UL94 V0 flammability, REACH compliance, and IP30 protection, with a design that supports safe operation in hazardous or controlled environments. These certifications help meet safety and environmental requirements for food-and-beverage, machine-building, and automation projects, reducing risk during audits and enabling faster product acceptance by systems integrators.
To maximize ROI, plan for front-mount panels to simplify field servicing and reduce downtime. Use the loaded contacts to speed wiring, ensure proper mating with push-pull coupling, and account for the lack of a backshell by routing cables to protect against debris. Consider inventorying the four-contact module as a standard SKU to streamline replacements.
