Allen Bradley Guardmaster 440N-G02028 Ferrogard Non-Contact Safety Interlock Switch

Maximise protection for personnel around dangerous machinery by securing your machine guard with the Ferrogard Non-Contact Safety Switch in ABS plastic, 4m Cable, by Allen Bradley Guardmaster. The Ferrogard range offers enhanced security and stability as they combine the reliability of non-contact switches with a high tolerance to door misalignment, giving you safe-access and ultimate peace-of-mind.

The 440N-G02028 Ferrogard magnetically actuated switch has a supply voltage of 250 V ac at 2A current, 1NC Safety Contact, and a 4m Cable. It features slim FRS6 rectangular housing made of red moulded ABS plastic, which suits narrow mounting areas for greater application flexibility. The operating distance is: make 12 mm, break 23 mm. It is designed to be installed on machine guards and doors and has 2 active sensing faces. This interlock switch is sealed to IP67 (NEMA 6P), making it well suited for use in wet environments as it can withstand temporary immersion in water, and it is also dust-tight. All Ferrogard safety switches have internal non-resettable overload protection on the safety contact and protected contacts to help ensure that they do not fail to danger, unlike some magnetic switches. The operating temperature ranges between -10°C and 65°C.

How it works: The magnetic actuator is withdrawn from the switch when the safety barrier is released. This opens the NC safety contact which then isolates power to the machine. This ensures that machinery cannot run while the guard is open, ensuring that personnel cannot access a hazardous area.

Features and Benefits:

• Two sensing faces
• High switching current
• High tolerance to misalignment due to large sensing field
• Non-contact actuation which ensures long service life due to less wear-and-tear, also allows simple set-up and the guard door can be opened immediately
• Sealed to IP67 (NEMA 6P) – fully protected against dust ingress and can withstand temporary immersion in water

Rockwell Automation is a global leader in industrial automation and digital transformation, and brings smart manufacturing to life. With a long legacy of creating Allen-Bradley® integrated control and information solutions, we help make you as productive as possible. Our portfolio of sensing, safety and motor control products can support your move towards smart machine applications. Allen-Bradley® IO-Link sensors are data-enabled and communicate with all field buses, providing diagnostic and health information about the device before a machine stops, and enabling quick production changeovers through fast parameter downloads from PLCs into the device. This reduces machine downtime and increases manufacturing OEE. For safety components, products with built-in diagnostics simplify the set-up of the smart device, and reduce maintenance, leading to a more efficient, machine data-driven approach.

What are the advantages of non-contact safety switches?

Non-contact safety switches are highly reliable and durable. They take less wear and tear and are low-maintenance, as well as resistant to shocks and vibrations. They cannot be easily manipulated or tampered with and are ideal for use with machine guards and doors to restrict access to unsafe areas. They are often used in industrial environments, such as in factory production lines. Allen Bradley Guardmaster, Rockwell Automation, are experts in machine safety devices and have an exceptional range to help you find your ideal solution.
