Keep your machine processes running seamlessly and ensure optimal protection for machine operators with the 440N-G02085 Ferrogard Non-Contact Safety Switch in Stainless Steel, 4m Cable, by Allen Bradley Guardmaster. This interlock switch is designed to be installed on a machine guard door. It provides greater security and stability as it has the reliability of non-contact switches and a high tolerance to door misalignment.

The 440N-G02085 Ferrogard Non-Contact Interlock Switch has 2NC safety contacts, rectangular FRS20 housing, and a 4m cable. It has a switching capability of 24 Vdc, 1A. This switch is ideal for use in wet environments as it has an environmental protection rating of IP67. The operating temperature range is -10 to +55 °C (+14…+131 °F) and the housing material is made of moulded ABS plastic in red. The operating distance for this switch is 12mm (make), 23mm (break). All Ferrogards have internal non-resettable overload protection on the safety contact.

How it works: The magnetic actuator is withdrawn from the switch when the safety barrier is released.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

• High tolerance to guard door misalignment
• M4 mountable in any position
• IP67 rated – Dust-tight and can withstand temporary immersion in water
• Non-contact actuation ensures less wear-and-tear and longer service life
• Externally fused non-resettable Safety Contacts

Note: This safety device can be used with Guardlink, a new safety linking technology from Allen Bradley Guardmaster. Guardlink simplifies and reduces the connection time of the safety 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 machine’s overall efficiency. For more details, please go to the Guardlink brochure.

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 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.
