Bsumwell RA Series IP65 Waterproof Plastic Junction Box: A Flexible and Reliable Protective Housing for Electronic Equipment

This product is the Bsumwell brand RA Series multifunctional waterproof junction box, manufactured from high-strength ABS engineering plastic. It offers eight standard size options ranging from 50x50mm to 200x100x70mm and comes standard with an IP65 protection rating, effectively preventing dust ingress and low-pressure water jets. It provides reliable, ready-to-use protection for electronic instruments, sensors, controllers, and wiring connections in outdoor and industrial environments.

Product Core Features

  • Flexible Multi-Size Selection: We offer eight compact standard sizes. You can select the most suitable model based on the size and quantity of internal components, optimizing space utilization to meet diverse needs from micro sensors to small controller modules.

  • Excellent Sealing Protection: The enclosure boasts an IP65 protection rating. Combined with the polyurethane (PU) material waterproof sealing gasket, it offers superior sealing performance and longer service life, effectively resisting damp, dusty, and corrosive outdoor environments.

  • Convenient Integrated Installation: The internal design prioritizes installation ease. Pre-drilled mounting holes allow for easy addition of standard DIN rails (35mm) to secure components like circuit breakers and terminal blocks. Pre-formed knockouts on the sides or base, fitted with 25mm/36mm rubber sealing plugs, facilitate cable entry while maintaining waterproof integrity. Custom drilling is also supported.

  • Sturdy & Durable Material: The housing is made of ABS engineering plastic, possessing excellent impact resistance, corrosion resistance, and electrical insulation properties, ensuring long-term stable performance in complex working conditions.
