Wide Operating Temperature: Functions reliably from -30?C to +80?C in extreme industrial conditions
Slot Sealing Plugs Included: Model 1476 plugs protect unused actuator slots from dirt ingress with simple clip-in installation
Padlockable Design: Key can be locked out during maintenance for enhanced lockout/tagout compliance
Double-Insulated Construction: Enhanced electrical safety in industrial environments
Compact Footprint: Space-saving 52mm x 75mm x 30mm dimensions enable installation in confined spaces
Applications: Essential for machine guarding safety in Virtus Equipment and ZERMA America shredders and granulators. Critical for preventing machine operation when access guards or safety doors are open, protecting operators from rotating knives, moving parts, and hazardous materials during processing operations. Ideal for recycling facilities, manufacturing plants, and waste management operations requiring compliance with OSHA machine guarding standards and EN safety directives. Perfect for applications requiring lockout/tagout capability during maintenance, high-vibration environments where standard switches may fail, and washdown areas where IP67 protection is essential. Suitable for explosive atmosphere environments with ATEX certification, food processing facilities requiring chemical resistance, and automated systems where positive safety interlocking prevents unauthorized access to hazardous machinery zones. Enables integration into safety PLCs and control systems for comprehensive machine safety architecture meeting Performance Level requirements.
