The Pilz PNOZ MSI B4 Box (Part Number: 773845) is a robust and reliable housing unit designed to protect and support PNOZmulti Classic safety system components. Engineered to combine durability with compliance to safety standards, this protective box ensures that the modules it contains operate securely and reliably in industrial environments.

Constructed from galvanised steel, the MSI B4 Box provides excellent mechanical strength and corrosion resistance, making it ideal for use in environments where reliability and longevity are critical. The galvanised finish enhances durability, ensuring resistance against wear and exposure to typical industrial atmospheres, which might otherwise compromise less robust materials.

With its IP20 protection rating as per EN 60529, the box is designed to prevent accidental contact with live or moving parts while still allowing for efficient heat dissipation within control cabinets. This makes it especially suited for mounting in enclosed panels or protected industrial spaces, where additional dust or liquid protection is not required. The housing safeguards sensitive safety relays and modules from mechanical impacts, ensuring consistent functionality of the PNOZmulti Classic system.

The operating temperature range of 0 °C to +60 °C provides versatility for use across a wide range of industries. Whether in standard factory environments, assembly lines, or automated machinery installations, the PNOZ MSI B4 Box ensures the protection and secure operation of safety modules without risk of overheating or damage due to ambient temperature fluctuations.

The box is designed to accommodate PNOZmulti Classic modules, which are widely used for implementing configurable safety functions such as emergency stop monitoring, guard door control, two-hand operation, and light curtain integration. By housing these modules within the MSI B4 Box, system builders can ensure compliance with international safety regulations while maintaining a clean and organised control cabinet layout.

Installation is straightforward, with the box engineered for compatibility with standard industrial mounting practices. Its compact form factor ensures it does not consume excessive cabinet space, while its solid construction provides long-term confidence in system integrity.

Industries that benefit from the PNOZ MSI B4 Box include automotive manufacturing, robotics, packaging, logistics, and general automation, where protecting safety modules is essential to maintaining productivity and operator safety.

In summary, the Pilz PNOZ MSI B4 Box (773845) is a purpose-built housing solution for the PNOZmulti Classic system, offering galvanised steel construction, IP20 protection, reliable temperature performance, and secure module integration. It is a durable, practical, and safety-compliant enclosure that ensures the long-term performance and protection of safety system components in demanding industrial environments.
