Maximise uptime, safeguard machine operators, and secure your guard door with the 440N-G02118 Ferrogard GD2 Non-Contact Safety Interlock Switch by Allen Bradley Guardmaster. This switch offers superior security and stability as it combines the reliability of non-contact switches with a high tolerance to door misalignment.

The 440N-G02118 Ferrogard safety switch has a 3m cable, 1NC Safety Contact, 1 NO Auxiliary Contact. The safety contact switching capability is 24V DC, 1 A max. The operating distance for this switch is 12mm (make), 23mm (break). It has resilient stainless-steel FRS2 GD2 housing to protect against impacts. It also has an environmental protection rating of IP68 (NEMA 6P). This means that it is dust-tight, and durable against temporary immersion in water. This versatile Ferrogard interlock switch has a wide operating temperature range of -25 to +125° (-13…+257°), for greater application flexibility.

How it works: The magnetic actuator is withdrawn from the switch when the safety barrier is released.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.

• Internal non-resettable overload protection on the safety contact
• High tolerance to misalignment due to large sensing field
• Excellent IP68 protection rating – perfectly suited for use in wet environments
• Non-contact actuation which ensures long service life due to less wear-and-tear
• Enhanced durability due to stainless steel housing, which protects against inadvertent impacts, housing is slim for application flexibility

Note: This device can be used with Guardlink, a new safety linking technology from Allen Bradley GuardMaster. Guardlink simplifies and reduces the connection time of the system, whilst providing real-time diagnostic information over an Ethernet IP. This makes it simple to identify the location of the device that has tripped the safety system, thus reducing downtime and improving the machines overall efficiency.

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.

Non-contact safety switches are low-maintenance and endure less wear-and-tear. They are also resistant to shocks and vibrations, and they cannot be easily tampered with or manipulated. This makes them highly durable and reliable. They are a cost-effective, ideal safety solution for machine guard doors and gates, allowing you to restrict access to hazardous areas where machinery may be in motion. For this reason they are often used in industrial environments.
