SMC Housing – Key Advantage for Industrial Use
The enclosure is made of Sheet Molding Compound (SMC), a high-performance composite material widely used in heavy industrial applications.
Why SMC is superior:
- Non-corrosive and resistant to chemicals, salt, and moisture
- UV-stable – does not degrade under sunlight exposure
- High mechanical strength and impact resistance (IK10)
- Electrically insulated, improving safety in industrial environments
- Lightweight compared to metal, simplifying installation
This makes the LC506-KB ideal for coastal areas, chemical plants, offshore facilities, and high-humidity environments, where traditional metal enclosures may corrode over time.
