Standard painted steel enclosures are not an option for outdoor applications. They will inevitably rust, allowing gaskets to fail and water to destroy your expensive PLCs, VFDs, and power supplies. Plastic enclosures, on the other hand, can crack and degrade under years of harsh UV exposure. This creates a massive reliability risk for any critical automation or control system.

MechStream now offers the ultimate solution: a professional Outdoor 304 Stainless Steel PLC Control Cabinet drawing. This is not a generic box plan. It is a fabrication-ready blueprint for a truly weatherproof, industrial-grade enclosure engineered to protect your most valuable components from the elements.

This design is centered on 304 Stainless Steel for its superior corrosion resistance, making it the perfect choice for rain, sleet, snow, and high-humidity environments. More importantly, our schematic details the critical sealing features, including a “knife-edge” return flange on the body and a groove for a foamed-in-place door gasket. This combination is engineered to meet a NEMA 4X / IP66 rating, making it completely dust-tight and resistant to powerful water jets.

By downloading our free CAD and PDF files, you get the plans to build a cabinet that will last for decades, ensuring your automation system remains safe, dry, and operational, no matter the weather.

Caractéristiques principales :

  • NEMA 4X / IP66 Design: Engineered with a knife-edge return flange and a deep gasket channel for a superior, long-lasting waterproof and dust-tight seal.
  • 304-Grade Stainless Steel: Specifies 304-SS (A2) construction for exceptional corrosion and rust resistance in outdoor and washdown applications.
  • Internal Mounting Plate: Includes a full-size, removable galvanized back-pan for the flexible layout of PLCs, DIN rails, terminals, and power supplies.
  • Secure Multi-Point Latching: Features a heavy-duty, multi-point locking system to ensure the door gasket compresses evenly and stays secure against tampering.
  • Rain Hood (Drip Shield): The design incorporates an integrated, sloped top (rain hood) to shed water and prevent pooling on the door gasket.
