Product Description:

The Rockwell Guardmaster 440N Non-Contact Switch is a magnetic proximity sensor designed for industrial safety applications. It uses Reed contact technology to detect the position and alignment of moving parts, such as safety doors, covers or flaps. The device operates without physical contact, which reduces mechanical wear and ensures a long operating life.

The sensor has a single safety output and a status output, both activated by the magnetic field of the drive. The IP67 protection rating makes it suitable for harsh environments, including dust and moisture.

Usage:

• Industrial Safety Applications: Used to monitor the opening and closing of doors, covers or safety barriers in industrial environments, ensuring operator safety.
• Automation and Control: Ideal for industrial automation systems that require feedback on the position of moving parts without direct contact.
• Machinery and Equipment: Integration with machinery requiring certified safety devices to prevent dangerous operations.

Advantages:

• High reliability: Non-contact technology reduces mechanical wear, improving durability and reducing maintenance.
• Harsh Environment Resistance: IP67 rated for protection against dust and temporary immersion in water.
• Safety Compatibility: Compliant with EN ISO 13849-1, level d, suitable for safety critical applications.

Notes:

• Installation: The sensor must be installed following the manufacturer's guidelines to ensure proper and safe operation.
• Positioning: Must be positioned correctly relative to the magnetic drive to ensure reliable detection.
• Maintenance: Periodically check the correct alignment of the sensor and the magnetic drive to avoid malfunctions.
